==What if I run a DNS server on purpose?==

It is quite legitimate for people to run DNS servers on their network - in these cases access to them should be restricted or limited.

It is quite legitimate for people to run DNS servers on their network, and we are happy for them to do so - in these cases access to them should be restricted or limited.

If you run an authoritative DNS server, configure it only to return records for your domain.

Line 42:

There is a page on the AAISP control pages that lists your IPs that have an open DNS server running, and can also re-scan your IP blocks (IPv4). AAISP will re-scan automatically every so often and will alert customers by email if an open DNS resolver is found. Sorry, but we don't have enough time to scan IPv6 addresses.

Log in to the [https://~~clueless~~.aa.net.uk/ Control Pages], and then either click on one of your IPv4 addresses or a broadband line. On these pages you'll see a link to the open DNS page.
