When I use DNSCheck to look up the A-record for the domain "demon-gw.ide.co.uk" I receive over 13Mb of HTML!
This highlights a configuration problem with zone ide.co.uk, which I fully understand, but am unfortunately powerless to correct. However, it is unfortunate that dnscheck produces such a large result (and a sizeable hit on the various servers involved).
FYI - the registration authority for co.uk (NOMINET) will not assign a tag to ide.co.uk as its registration ownership is unclear. It is in the odd state of having NS records for four servers, three of which are in the ide.co.uk domain itself, but no corresponding glue A records.
