What is DNS?

DNS stands for Domain Name System. DNS is the method of searching for IP addresses in a huge collective database that contains domain names. Since computers and electronic devices operate on the Internet Protocol, or "IP", browsers translate domain names to IP addresses.

How does DNS Work?

When you enter a domain name into your browser ,such as www.findmyip.co, a request is made to your Internet Service Provider (ISP) by your network. Usually, this request comes from your cable modem or DSL modem, which comes from your router and ultimately from your device. The ISP checks to see if it has the IP address of the domain. If the ISP doesn't have the IP, it forwards your request to multiple other ISP's to see if they have the address. Once the IP address is found, the ISP returns the information to your modem/router, which send the IP address to your computer.

Once your computer has the IP address, it can then request the web page information directly from the web server. The web server stores all the information for the website.

What is Dynamic DNS?

IP addresses come in two forms: static IP addresses and dynamic IP addresses. Most home Internet users have dynamic IP addresses that are assigned by the ISP. Dynamic IP addresses change while static IP addresses NEVER change. Internet Service Providers change IP address assignment because of a world-wide shortage of IP addresses using IPv4.

Some Internet users need to update their domain name servers automatically. Usually, updating DNS manually is not practical. Since dynamic IP addresses can change frequently and without your knowing, failure to update DNS can result in errors.
