How are DNS records laid out?

If you're never setup a DNS record before it can look intimidating but it's actually fairly straightforward.

  • Type (Record Type)
    If you're not sure what this is see our guide on types of DNS record.
  • Key (Host Name)
    This is the bit you want, the prefix, before your domain name. The most common is of course 'www' but there are others. You'll notice we use 'business' for There are 2 main special ones. The first '@' is known as the blank record and is used for situations without any prefix, for example, The second is '*' and will take effect for any prefixes you haven't added. This can be very useful to direct someone to your site even if they mistype the prefix (e.g.
  • Value (Address)
    Most commonly this will be the address of your web server or email server.
