==4. Generic Per-IP Block==

Support staff can add a name on a per-IP block basis and we'll automatically create reverse records, e.g., if your block is <code>81.187.81.0/29</code> and we add the name <code>hosts.testing.me.uk</code>, then we'll create reverse records such as:

<code>0.hosts.testing.me.uk</code>

<code>1.hosts.testing.me.uk</code>

<code>2.hosts.testing.me.uk</code>

etc.…

Contact support staff for this.

=b. Delegating reverse DNS to your own nameservers=

Line 66:

Line 57:

We have two main ways of setting up the delegation of reverse DNS to your own nameservers, and you can select which you prefer using the control pages. In both cases the task is to set a reference on our system to the name servers that you manage and that will give the answers for reverse DNS queries. The reverse DNS name server boxes on the control pages let you specify one to six name servers (by name, not by IP address) for your name server(s). Don't put a dot on the end of the name though.

This setting is found on the control pages under the link to your Login. This will apply to IPv4 and [[IPv6]].
