Network and reverse DNS

IP address

Every virtual server gets its own static public IPv4 address. It is routed straight to the server, with no address translation (NAT). The server's Network tab shows the address, along with the netmask, the gateway and the DNS resolvers where those are set.

  • The address is kept when you reinstall.
  • The network is configured statically when the server is built. Do not change it to another address: only traffic leaving from the server's own address is let out, and packets with any other source address are dropped.
  • IPv6 is not currently provided for virtual servers.

To point a domain at the server, add an A record for the server's IP address in the domain's DNS.

Reverse DNS (PTR record)

Reverse DNS says which name belongs to an IP address. It matters most for a mail server: many receiving servers treat mail as suspicious when the sending IP address has no matching name.

  1. First, add an A record for the name you want (for example mail.example.com) pointing at the server's IP address.
  2. On the Network tab, click Request reverse DNS and enter the full host name.
  3. One of our staff approves and sets it. Its state is shown in the same place: waiting for approval, set or refused.

One request can wait for approval at a time; you can withdraw a pending request.

Traffic

If your plan includes a monthly traffic allowance, the Overview tab shows how much of it you have used. The allowance applies to outbound traffic and is counted per calendar month.
