Dynamic Domain System is a process of keeping a domain name linked to a shifting IP address as not every computer out there uses a fixed IP address. Usually, when a person connects to the Internet, the person’s internet service provider assigns a brand new IP address from a group of IP addresses, and this address is used only for the duration of that specific connection. This manner of dynamically assigning addresses broadens the usable group of available IP addresses. A dynamic domain name system provider uses a particular program that runs on the user’s computer, contacting the domain system service each time the IP address provided by the internet service provider changes and subsequently updating the domain system database to imitate the change in IP address. In this way, even though a domain’s IP address will change often, other users do not have to know the changed IP address in order to connect with the other computer.
When any domain name system server resolves your domains information it will store it so the next time it can react faster. Occasionally it may store the data for several days. If anyone searches your domain and gets old or stored information they will not be able to reach your services until their DNS server has the new information. If our company hosts your domain we specify a low time to live on all searches. This tells all other DNS servers on the web to only store your records for a short amount of time and to come back and re-search for new data after that. This results in faster duplication of your new IP address throughout the web. Dynamic DNS is not just for users with dynamic IP addresses. Dynamic domain system can also be used for fixed IP addresses that need to be changed every so often, for example when you change web-hosting providers, move from one internet service provider to another, etc. This diminishes or removes the downtime between the switch from one IP to another.
