What is DNS?

Without this, the internet would be all about numbers and unmemorable things.

By Joao Lima

DNS stands for domain name system. This is what controls websites’ names and associate emails if there are any.

The DNS is what controls which server is used when users visit a website.

One of the biggest advantages of DNS is its capability to hide IP addresses behind a more memorable name. For example, instead of coming up as 193.109.254.26, a DNS allows CBR to be simply presented as www.cbronline.com.

DNS is part of the Internet Protocol Suite, a model and comms protocols used on the internet and other computer networks.

Different elements control different areas of the domain name. Find out more on the next page.

Within the DNS ecosystem there are different elements that have been created to control different aspects of the domain.

These include the nameserver, zone file, a record, domain name aliases or canonical name reacord (CNAME), and MX records.

The DNS also stores all internet domains in a database and corresponding IP addressed so it can match websites’ URLs to IP addresses.
