Addresses and reverse DNS
See every address on your server, set the reverse DNS name for each, rename the server, and ask for another address.
Every address is on the server's Networking tab, under Addresses. You need the netmask and gateway if you set the network up by hand.

- 2Edit Opens a box to type the reverse DNS name, for example
mail.example.com, then Save. - 3Set by us This address's reverse DNS can't be changed here. Open a ticket if you need it changed.
Reverse DNS is the name an address looks up to, which mail servers in particular check. Other servers see a new name as their caches catch up, which can take a while.
Rename the server#
Press Rename beside the name at the top of the page, type the new one and press Save. It changes the name in the portal and the one the next install is given, not the hostname inside the running system.
Another address#
- 1Ask for one Opens a ticket for an extra IPv4 address. We add it and tell you when it's ready.
- 2Talk to us Opens a ticket about more memory, disks or a bigger machine. We'll quote it.
