Dynamic Domain

Do you know what a dynamic domain name service is?. It is a method of keeping a site name joined to a changing IP address as not all computers use static IP addresses. Usually, when a user connects to the internet, the ISP of the user assigns an unused IP address from a pool of IP addresses. And this address is employed just for the period of that specific connection.

Unlike DNS that only works with static IP addresses; DDNS is meant to also support dynamic IP addresses; like those allotted by a DHCP server. that creates DDNS a good fit for home networks; which regularly receive dynamic public IP addresses from their internet provider that often modification.

Having a Dynamically assigned  IP addresses is a lot like having to alter your number once each day. If others need to connect with your computer they’d have no means of knowing your current number. The necessity for a static IP address comes from those users who want to run server software system like internet Servers, FTP Servers, Game Servers, Email Servers or run business related services such as VPN’s , Remote Access software. There are several different needs for Static IP addresses as well.dynamic domain name service

Dynamic DNS comes into play when a web user either cannot afford a static IP address. Or obtain a static IP address from there ISP. Operating very similar to an old style phone operator. Dynamic DNS allows a user to update a DNS server automatically each time there IP changes. Thus anyone who needs to attach to the users computer will always reach his server by getting into the users domain name. The entire method works despite the changing IP addresses.

In order to have dynamic DNS service work for you there are two things you have to do:
  • Set your name up to use dynamic DNS service on easy DNS.
  • Download and setup a dynamic DNS customer on your computer.

To use DDNS, you just need to signs up with a DDNS provider and installs network software on their host to observe its IP address. For example, dyndns.com offers a free dynamic DDNS service via software that may run on Linux, Windows or Mac computers. Compared to normal DNS; the disadvantage of DDNS is that extra host software, a new potential failure point on the network; should be maintained.

Now looking closer at internal networks, larger ones are usually divided into different DNS zones. There are many other ways that this will be organized with regard to DNS configuration. Once planning any name resolution service it’s necessary to take into consideration what would happen if a DNS server were to fail. If that server fails, the users won’t be ready to access any internal resources unless they understand the IP address of the resource that they’re attempting to access
