Inexplicable DNS

Can anyone see where my problem is coming from?

I have a nameserver configured at ns1.trampolining.net (212.19.91.250) and
interrogating that IP address gives the correct IP. However, use any other
nameserver on the internet and you get ns1.trampolining.net resolving to
62.232.33.138!!!!!

The whole caboodle is copied to a backup server, ns1.secondary.com

Can anyone see my mistake as I can't find any mention of the mystery
62.232.33.138 anywhere!!!!

Help!

Well other people aren't going to know to look at 212.19.91.250 to find
the A record for ns1.trampolining.net. They are going to start at the root
and then work their way down to one of the .net servers and get the
following information:
dnsq ns trampolining.net a.gtld-servers.net
2 trampolining.net:
149 bytes, 1+3+0+3 records, response, noerror
query: 2 trampolining.net
answer: trampolining.net 172800 NS ns1.secondary.com
answer: trampolining.net 172800 NS ns2.secondary.com
answer: trampolining.net 172800 NS ns1.trampolining.net
additional: ns1.secondary.com 172800 A 198.133.199.3
additional: ns2.secondary.com 172800 A 198.133.199.4
additional: ns1.trampolining.net 172800 A 62.232.33.138

And since the .net dns server says that the IP address for ns1.trampolining.net
is 62.232.33.138 that is where they will look (or possibly at one of the
other addresses given).

Thanks for your help. It turns out that while with Dotster you give the
NAME of your nameserver rather than name and IP, there is a page you use to
register the IP of the nameserver. It was this page I missed out when
changing the IP on the Linux box.

So I was searching desperately for an error in the Linux config that wasn't
there!

Cheers!

It works from here. Perhaps you just needed to wait for the TTL to
expire on the servers you were checking.

bobh@nuthatch:~$ host ns1.trampolining.net
ns1.trampolining.net A 212.19.91.250
