I've a sneaking suspicion that will cease to happen once chenks76's rDNS has been corrected.

My sneaking suspicion appears to be wrong
Very odd indeed. The SOA record points to centralnic.net who are returning valid A/MX records etc. despite the domain not being registered

[#3]

205.164.14.88 is not my IP address though

[#4]

No it's not, it's just peculiar that agcomputers.uk.com has a forward DNS entry when it's not even a registered domain. It's nothing you need to be worried about.

[#5]

It's not agcomputers.uk.com that has a forward entry, it's EVERYTHING .uk.com because Centralnic have set up a forward entry with an asterisk "*.uk.com" to catch-all currently unregistered .uk.com subdomains and put up ads. This is precisely the kind of thing Verisign did with .com many years ago that caused awkward diagnostic problems like this until they were forced to remove it. Unfortunately Centralnic is not breaking any rule here, they are free to do anything with uk.com as they see fit as it's their domain, they sell subdomains. Personally I think this wildcard is inappropriate as it means that technically every possible entry 'exists' even though it shouldn't, with no error. *shrugs*.

[#6]

So they do!

C:\Users\John>nslookup centralnic_suck.uk.com 212.159.6.9
Server:  cdns01.plus.net
Address:  212.159.6.9
Non-authoritative answer:
Name:    centralnic_suck.uk.com

So they have! Could probably have worked that out if I'd actually tried browsing to the domain
Thanks for the explanation.

Well after changing to my new static IP, my reverse DNS has changed back to default again!
Come on PlusNET, sort this out please! 

[#9]

I've changed your rDNS back, please allow 24 hours for it to take effect.

Hi,
I've just noticed this has happened to my IP address. I think it's only happened in the last week or so. My rDNS had been changed to x-x-x-x.plus.com but now it's back to username.plus.com.

Hi Andy,
I've changed it back for you.

Thanks Bob
