DNS records are edited from the control panel, under Domains.

## The records most people need

– `A` points a name at an IPv4 address.
– `CNAME` points a name at another name.
– `MX` says which server takes mail for the domain.
– `TXT` carries verification strings and mail policy.

## Time to live

The TTL is how long other servers are allowed to remember the answer. Lower it to 300 seconds the day before a planned change, then put it back afterwards.

## Nothing happens straight away

A record you have just changed may be served from a cache elsewhere for as long as the old TTL. That is normal and is not a fault with the record.
