The Domain Name System (DNS) works like the yellow pages of the Internet. When you type a domain name such as public-internet.co.uk or google.com into your web browser, a DNS server is responsible for looking up the IP address for the website. Your browser then uses the IP address to contact the right server to retrieve the website you have requested.
Recursive DNS servers are normally configured in your router and allow your device to lookup an IP address when you try to access a website. If you are using a broadband service these will normally be configured automatically however if you need to set them manually you can use the settings below.
Authoritative DNS servers hold the DNS records for your domain name and provide answers to other DNS servers when someone tries to connect to your website. If you have registered your domain name with us you can set the authoritative DNS servers through our customer portal. If you have registered your domain name with another provider and want to point your domain name to a DNS service provided by us, you should use the settings below.
