DDNS is the Dynamic DNS term. This technology resolves the problem of changing dynamic IPs in connection with domains. In the world of the Web, there is a need for a proprietary and proprietary IP to pay high fees to service providers or ISPs.
Also, since domains are only capable of having an IP, you will need to use dedicated IPs. This means that the dynamic IPs you receive from your ISPs will not be able to connect to the application domain.
This problem of dynamic dynamic IPs is address by using DDNS. By deploying DDNS, you can connect your personal domain to the dynamic IP of the ISP and automatically update the IP to update the new domain name.
Before beginning to provide explanations about the nature of DDNS and its uses in the web, we first need to briefly discuss the overall DNS topic. DDNS is actually technology that extends beyond the DNS service platform without that meaning.
The DNS, the Domain Name System, is a service that connects domains to IP addresses over the Internet. In fact, it’s the DNS that has been built with multiple Internet servers as you know it.
The problem with DNS is that you can only have a fixed IP address (Static IP).
As noted above, DDNS is designed to resolve this DNS constraint and enables you to use dynamic IPs to connect to domains without the need for a fixed IP (which usually costs it high). Get yourself
DDNS is a good choice for home systems, which is generally assigned an IP address via DHCP.
How does DDNS work?
You might be wondering how Dynamic DNS works. The DDNS monitors the changes occurring in the IP address. When the address is change, your DDNS service will update the DNS Zone domain with the new IP address.
Dynamic DNS can be useful for people who want to access their networked CCTV cameras from their home computer, or access their own application and website.
The reason for the usefulness of DDNS is the low cost of a public IP (Dynamic), which you can have at no extra charge with your Internet connection. With the launch of Dynamic DNS, you no longer need to manually update and update your DNS Zone domain.
This technology is of paramount importance when some ISPs do not generally provide IP static based on their internal policies.
Dynamic DNS is a flexible solution. DDNS allows Internet connected devices to receive new information after changing DNS servers, and there is no need to change IP addresses by network administrators.
Benefits of DDNS
As explained and seen above, Dynamic DNS is a simple and practical solution that has several different points that we will look at the most important ones.
Access – You can access your website or server easily and without any worries. The IP may change, but with DDNS it will not affect the performance of your service.
Applicable – By deploying this technology you no longer need to have a network administrator because there is virtually no need for this person to update and change the network.
Economics – DDNS eliminates the surplus costs of dedicated IPs and you can pay for your network without paying your own Internet costs.
There are many other uses for this technology, and of course you already have a few of them.
Using this service is very easy. Just create a free account at one of the DDNS provider companies and put your domain DNS on the values they provide.
You need 2 other services to run DDNS along with your servers and devices. In fact, the two services mentioned above are the technical prerequisites for DDNS.
1) Valid Domain – You need to register domain to connect to your dynamic IP with the help of a hosting company.
2) DDNS service – You will need to provide this service from a third party to use this service.
Dynamic DNS Means Anytime, Anywhere Network Access
Because ISPs don’t assign static IP addresses, accessing devices your network remotely is tricky. One way around changing IP addresses is to use a Dynamic DNS service, which automatically tracks the changes to your network’s public IP address.
You pobably use your broadband connections for all kinds of things when you’re at home, but you can also take advantage of that connection to access devices on your network even while you’re away. For example, you might want to view a Webcam, grab files off an FTP server, use a remote access utility like Windows’ Remote Desktop [define], or even access the router itself to administer it from afar.
These sorts of things would normally be made possible by a router’s port forwarding feature [define] combined with knowing the public, or global, IP address assigned to your network by your ISP. The problem is that for most accounts, that public address isn’t permanent and will change from time to time.
It may not change very often — maybe every few days or perhaps even less frequently than that — but once it does, the address you’ve become accustomed to using won’t work anymore.
While you can always find the new IP address and begin using it instead, you can’t look it up while away from home. Even if you could, the address will eventually change again.
