No ip com input. Create your own permanent IP address


Video surveillance via the Internet is becoming more popular and accessible every day, but not everyone has the opportunity to use a dynamic IP address or resort to services. An alternative option for connecting CCTV cameras to the Internet and then viewing the image on any device with Internet access is to set up DDNS, or assign each IP camera or DVR a separate permanent domain name.

DDNS stands for Dynamic Domain Name System, and can convert your dynamic IP address into a domain name, which you can then simply type into the address bar of your browser from any device connected to the Internet and access the camera image.

Step 1: register on the NO-IP service

One of the services that provides the opportunity to create a domain name for an IP address for free is Noip.com. We follow the link to the site, and in the first line you are immediately asked to enter the desired domain name. Enter any name that comes to mind and click on the green button.

You will now be redirected to the registration page. We enter a username and password, and also indicate an email address to which you must have access, since a link to activate your account will be sent to it. After all the data has been entered, click on the “Create My Free Account” button.

After registration, you will have your own free domain (for example, nabludaykin.hopto.org), now NO-IP will offer you a small guide on the necessary steps:

  • Step 1 - Create a hostname. (This step has already been completed);
  • Step 2 – Download the Dynamic Update Client (DUC). DUC stores your hostname, and is updated with the current IP address. (You don't need to download this tool as IP cameras and DVRs have built-in DUC);
  • Step 3 – Forward the router ports. We will dwell on this point in more detail.

Step 2: Router Port Forwarding

Now let's move on to the router settings. Port forwarding is the process of setting up a router to gain access to the DVR, cameras or any other network device from computers and other gadgets located outside the local network. Port forwarding allows you to assign an IP address and port number for routing network requests to specific devices.

You need to do port forwarding for the IP address of the NVR or . For example, the local IP address of the DVR is 192.168.0.188, then you need to go to the router port settings (usually located in the “virtual server” tab) and add port forwarding rules. Below are the interfaces of the 4 most popular manufacturers. Keep in mind that your router may display a different interface, but the logical structure in almost all devices is that the path to the virtual server settings is intuitive.

Step 3: set up DDNS on the DVR

After entering the settings of your DVR, go to Settings > Network > DDNS Setting, check the “Enable DDNS” checkbox, then select “No-IP” in the “server type” line. For each equipment manufacturer, the names of the items may differ slightly, but the principle remains the same.

Fill in your No-IP service account information:

  • Server type: No-IP
  • Server name: dynupdate.no-ip.com
  • Port: 80
  • Username: admin@site
  • Password: ******
  • Confirmation: ******
  • Domain: nabludaykin.hopto.org

Then log into your DVR's web interface, go to Network Settings > DDNS Settings, check the "enable DDNS" box, and then select "No-IP" from the list provided. Fill out the form with your available domain name, and then enter your account login and password.

After completing the above steps, you can visit your NVR with a free domain from any device by going to the address you provided, in our case nabludaykin.hopto.org.

Step 4: connect cameras

To properly configure DDNS for video surveillance, you need to make sure that the IP cameras and the DVR are connected to the same router and are also located on the same local network. To do this, you need to check the network settings of each device. We enter the IP address of each camera in the address bar of the browser, and we get to the network interface of the device. Here we need to tidy up the IP addresses of each camera and place them in the same subnet with the DVR.

If we configured the DVR as follows:

  • IP address: 192.168.0.188;
  • Subnet mask: 255.255.255.0;

Then the IP camera parameters should look something like this:

  • IP address: 192.168.0.21;
  • Subnet mask: 255.255.255.0;
  • Default gateway: 192.168.0.1.

Other dynamic IP address services

ChangeIP.com. Another reliable DDNS service. Today, the service offers free assignment of a domain name to a dynamic IP address; you can get up to 7 free sub-domains.

DNSExit.com. This service offers free DNS hosting for your own domains. If you don't have your own domain, you can also use their free DNS service with domains like publicvm.com and linkpc.net, after registering you can get two free sub-domains.

DNSExit is a professional DNS service provider. The company offers a free dynamic DNS service to users all over the world, and you can register your domain for free, or use a free second-level domain (sub-domain). A free second-level domain allows you to create a host name and specify a dynamic or static IP address.

Afraid.org. Quite an old provider of free DDNS - the company has been providing free dynamic DNS registration since 2001. Until now, their website is still open for free DDNS registration.

No-IP is a best-in-class application that is also capable of working with dynamic IP addresses. In fact, it doesn’t matter what kind of Internet connection you use and what your address is, as well as what subnet it is from. With this program, users can easily visit the server installed on your computer because... Instead of four sets of numbers, you can be found by an easy-to-remember domain name.

Get a name for your computer that is very easy to remember.

Typically, IP addresses that are assigned to a computer are very difficult to remember. You don’t type the address “66.218.71.113” in your browser in order to get to the page of one of the most popular search engines, which is available for viewing at yahoo.com? With this program, your computer will have a name, not just a numeric address. Using this software, you can have servers on your computer that will be as accessible as the largest sites on the Internet.

Make your location permanent

If every time you connect to the Internet your computer is assigned a dynamic IP address, then by installing this program you can solve this problem. But that's not all, regardless of where, when, to which provider and using what type of connection (Dial-up, DSL, high-speed cable connection or wireless connection) you connect, you will always have the same address in in the form of your chosen name.

Ability to shorten your favorite URLs

If you want, you can shorten and simplify links to your favorite Internet pages. For example, the link "www.someisp.com/subscribers/j/s/~jsmith" can be turned into a simpler version like "jsmith.hopto.org" for free.

Key Features and Functions

  • the ability to automatically configure the network, which makes the installation process much faster;
  • ease of use. The client downloads everything from the hosts that are associated with your account. Just check the ones you want to update;
  • ability to use encrypted data. When updating, requests are encrypted to ensure data integrity;
  • can work as an NT service. You do not need to launch the client every time you restart your computer.

Special Requirements

  • processor: 266 MHz or better;
  • RAM: 64 MB;
  • free hard disk space: 5 MB;
  • Internet connection.

Note: No-IP is free for personal use only. If you expect high traffic or commercial use, then check out the No-IP Enhanced or No-IP Plus programs.

Good afternoon. Dynamic DNS server services are increasingly gaining popularity, as they allow you to bind a domain name to any computer, which greatly facilitates access to or. A long time ago I wrote the first instructions on this topic, but it was dedicated to, in it I described a way to bypass the mandatory paid subscription on the server by registering on an affiliate service from D-Link, but recently this hole was patched with a banal method, now regular confirmation is required that you have D-Link network equipment. I have a TP-Link router, so my account has already been deleted, so now I finally got around to writing about the neighboring project No-IP.com, which provides up to 3 third-level domain names for free.

Step-by-step instruction

  1. So, the first thing you need to do is register. Therefore, follow the link and fill in your data: www.noip.com. After filling in all the data, click on the button Free Sign Up.
  2. After completing all stages of registration, go to your personal account and go to the tab Manage Hosts. Click the orange button here Add a host.
  3. We come up with and write down the host name in the field hostname, then select a second-level domain. We also write down our current IP address (). Press the button Add Host
  4. That's it, now all that remains is to make sure that our current IP is automatically updated on the service. There are two options for this: specify your credentials in the router menu or install a no-ip client. The latest version of the client can always be downloaded at www.noip.com/download; you are unlikely to have any problems setting it up. I prefer to configure it in the router menu and for me it looks like this:

Linking a domain name to your computer

As I wrote earlier, if you have a domain name, you can link it to your computer. To do this, you need to register a CNAME record in the DNS editor of your registrar with the value of your domain received on dyn.com. For example, I made an ftp subdomain.. And in the Yandex DNS editor interface it looks like this.

I am rather paranoid and until now I have kept all access to the local area from the Internet closed. Although, on the other hand, even a physical shutdown does not provide a full guarantee, as removable media remains. And if transmission, bttorrentsync, etc. works... In general, several applications have been invented that require external access to the local area - owncloud, remote backup via the Internet, etc. Let's start with DDNS

Let me warn you right away that Captain Obvious is with me. Just for a beginner, I’ll try to put it in simple words.

Let's start with a simplified theories. On the global network, the right to use an IPv4 address (for example 95.24.156.147) can be obtained from the authority, IANA. Total addresses 2^32 (~ 4 billion), part given for special purposes - not enough for everyone. This is partly why an isolated home network usually uses addresses like 192.168.0.0/16, which are the same in all such networks. This allows you to save address space. But as a result inside the home network and outside the addresses are different. Your network receives one external address, from the provider (to whom you pay for the Internet). And they give him away for rent for a while, and can be changed at any time. Therefore, it is somewhat difficult to reach your home network via IP. There are two main ways - rent a permanent (static address) from your provider. For example, with my provider it costs 130 rubles/month. This is worth doing if you have important applications, such as client-bank, because... a static address has a positive effect on security. But in most cases, the second method is easier - DDNS.

The essence DDNS is that you assign someone (the DNS server) to track changes in your real, dynamic, IP address and associate this address with a permanent name, for example vasia_pupkin.ddns.com. In order for the DNS server to know about the changes, someone from your network must periodically connect to this DNS server, log in and report their current IP. Usually this work is performed by the router.

The good news is that in its simplest, home-friendly form, DDNS services can be found for free. Choosing a provider DDNS- the topic is long, start with the list that your router supports. Google yours, many routers can do this. If it doesn’t, nas4free can take over this role, Services|Dynamic DNS (I didn’t set it up, but everything is similar there). , for example, suggests the following

As seen, I chose no-ip. Simply because it works. Let's set it up.

1) Register at https://www.noip.com/newUser.php, this is a free option. Many places will offer paid upgrades, this is not required for the home.
As always, you will need your email address. It’s bad that mail.ru won’t work. yandex.com and google.com - accepts.

2) Go in and get to the graphic menu


Select "Add Host"

3) We get into the dialogue below (you can also get into it through the menu - Add Host)


There are a lot of fields, there are more below. But in the simplest case, you only need to fill in two
Hostname- choose something instead of vasia_pupkin
And from the long list to the right you need to select a second-level domain. no-ip.info good for free service. Most of the rest are offered for the opportunity to ask you for money.
There is no need to fill in the IP address - the system determines it itself. But if you fill it out, nothing will change.
Click the orange Add Host button below - you're done.
Note - the functionality of the service is broader - it may come in handy later.

4. Now all that remains is to configure the router (or NAS) to knock on no-ip and report your address. Using my router as an example, yours (and nas4free) are all the same.

Follow the checkboxes - enable the DDNS service, select the no-ip provider from the list, provide the name of the created host, login and password for connecting to no-ip, and apply.

5. Communication check. All that remains is to check. The natural instinct is to type vasia_pupkin.no-ip.info in your browser's address bar (do this)
Oops! We are asked to log into the router's webgui! So, now any kulkhatskher will come to visit me as if it were his own home?!!
The answer is both yes and no. That is, the robots will break in and, if you later open the channel, they can pick up or even eavesdrop on your passwords.
No, because you haven't discovered anything yet. You simply led those who knew your domain name vasia_pupkin.no-ip.info to the router door that was closed from the outside. By the way, this is a reason not to highlight your chosen domain name in vain.

And you see an invitation to enter the router login password because you approached the same door from INSIDE, from the trusted zone.
You can verify its functionality by pinging your domain from the command line
ping vasia_pupkin.no-ip.info
If it works you will get something like
PING vasia_pupkin.no-ip.info (96.28.157.147) from 192.168.1.34: 56 data bytes
64 bytes from 95.27.155.134: icmp_seq=0 ttl=64 time=0.283 ms
64 bytes from 95.27.155.134: icmp_seq=1 ttl=64 time=0.292 ms
64 bytes from 95.27.155.134: icmp_seq=2 ttl=64 time=0.198 ms

Here you can see that (1) the name (vasia_pupkin.no-ip.info) is resolved to the external IP (96.28.157.147) - which means the service is working and
(2) that the transit time is very short, fractions of a millisecond, that is, the packets travel locally.

6. To get outside, you need to go outside :). It's not so easy at home. You either need to go to work, visit a neighbor or friend, or connect to another provider from home. The average user can do the latter by connecting via mobile communications. For example, I plugged a 3G modem into my laptop.
Let's ping again. As a result, the name should still be resolved to the same IP, but if you have a normal router, there should be no ping. If your router is already pinging from the network, this may not be so scary, but it’s a bad sign and a reason to think about replacing it. My option, let me remind you, asus
