>>> I would be asking operators of primary-dns.co.uk why they are actively cache poisioning. >>> They have not been delegated aaisp.net.uk so they should not be serving aaisp.net.uk. >>> Mark This is where my knowledge of DNS-configuration and RFCs starts to reach its limits, and I welcome your thoughts But I can certainly help provide a bit of background information. See: http://aaisp.net.uk/kb-broadband-serverlist.html And: http://aaisp.net.uk/support.html AAISP are a UK-based ISP, and pride themselves on being technically-friendly and I'm sure that if your are able to help identify a problem in their confirguration, they would welcome your input. >From what I understand, they run both an "authoratitive DNS server" (for domains that they host) and also a "customer-facing caching-resolver" ... They also fully support IPv6 and have done some extra DNS-server coding to integrate with an internal clustered mail-system... I believe that one of their two systems runs {Unbound DNS - http://www.unbound.net/) and the other runs Bind, but I'm not certain of this. --- I also just noticed the following (not sure if this is any help to you) C:\>nslookup -q=ns wilmot.me.uk Non-authoritative answer: wilmot.me.uk nameserver = primary-dns.co.uk wilmot.me.uk nameserver = secondary-dns.co.uk C:\>nslookup -q=ns aaisp.net.uk aaisp.net.uk nameserver = auth.primary-dns.co.uk aaisp.net.uk nameserver = auth.secondary-dns.co.uk --- Steven _______________________________________________ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
