Very often, many users unfamiliar with the intricacies of setting up Internet access are faced with a reduction such as DDNS. What is it, some just do not imagine. Meanwhile, there is nothing unusual in understanding this term. Next, brief information will be given regarding what it generally is, how it all works, and why it is needed.
Let's figure it out: DDNS - what is it?
The concept of DDNS as one of the varieties of DNS servers has appeared by modern standards relatively recently. As you know, a regular DNS server is in some way an interpreter for translating a domain name into an IP address. Previously, when there were not as many computers connected to the Internet as they are now, it was somehow still possible to remember the addresses of machines or sites in digital terms. But over time, permanent (static) addresses for all devices, including both computers and mobile systems, were simply not enough.
It was then that DDNS technologies were introduced. What it is? In simple terms, these are servers (services) that provide computers with dynamic external IP addresses, but monitor the binding of the domain name to such changes.
Dynamic DNS: how it works
Suppose a user has created his site and placed it on some kind of hosting. Well, if he himself comes to other resources from his terminal, but feedback should be provided, and other people should visit the created site. But how to do this if the address of the computer is constantly changing?
This is where the DNS server helps, which constantly monitors the IP change and associates it with the domain name. Roughly speaking, if a user named his resource vasya.com and set a dynamic IP for him, any other person, when entering such an address in the browser, will be directed to the attached user terminal or Vasin’s website without any problems. The DDNS server or Dynamic DNS is responsible for this.
Most Popular DDNS Services
These are, in general terms, DDNS mechanisms. What is it, I think, is already becoming clearer. Serving a dynamic address is not at all complicated. To do this, you should use special services that provide such services. Needless to say, they can be both paid and free.
But the following services are recognized as the most popular, the addresses of which are given below:
- dyns.cx;
- dhs.org;
- 3322.org;
- update.ods.org;
- no-ip.com;
- dyndns.org.
The last resource is the most popular, and all settings are most often made specifically for it. Further, the parameters set on the routers will be given specifically for him.
Preliminary Actions
Before you deal directly with the settings, you must register in the service. This can be done directly on the official resource, after which the domain name will be tested for uniqueness, and then the user will receive it at his disposal (it will be used in further settings).
Among the data entered, you will need to indicate the first name, surname, region of residence, email address, etc. This is necessary to create the so-called user card. After completing the registration, a domain name (for example, vasya.dydns.org) and an account for direct account management will be created.
Customization
Now let's see how DDNS configuration on the router goes:
- First, we go through the browser to the settings of the router by entering 192.168.0.1 or 1.1 in the address bar.
- In the options menu or advanced settings we find the DDNS section.
- After that, we select the service in which the registration was made, and enter the data in all the fields to be filled.
- If there is an activation field in the settings, enable the checkbox on the Enable parameter.
- Next, just save the settings.
Possible problems
Sometimes, but very infrequently, you can meet a situation where all the parameters seem to be set correctly, and the service is activated, and access by domain name is still impossible. Alternatively, you can use the entrance to your account card, where you just need to specify the domain name received. If this does not work, you can enter a valid address assigned to the WAN port. IP should appear in the settings. After that, access to the router will appear.
However, do not neglect communication failures, the basic settings of the router or the network protocol used to connect . If something goes wrong, you can use the diagnostic tool that is available on every Windows system to identify errors.
Conclusion
It remains to be added that the use of dynamic IP addresses is quite a promising direction today, even though Microsoft is everywhere trying to implement the sixth version of the IP protocol, which involves the allocation of a lot more static (permanent) addresses than the fourth.
The setup, as you can already see, is very simple. The only and most important condition is registration in the service itself, which provides such services. What to choose from all this? Most choose DynDNS, although other Internet resources are no worse. But here you already have to dig a little yourself and evaluate the advantages and disadvantages of a particular service.
