I get a response from that IP as well, however from mine, I don't, I
suspect that's the server cache.
Is this IP range still delegated to you?

Querying your server gets a response, but like mine, none others seem
to, what changes have you made recently?
a Te$ltra server I query also knows it, but my secondary DNS (located
in California) does not either, nor does ns1.exetel
so somethings changed
None of the servers listed other than my local caching lookup server
belong to us / are maintained by us. The 47.30.22.203 is a customer of
ours who's email into our domain is being rejected due to reverse lookup
failing in our local caching nameserver, the other dns mentioned is one
belonging to a hosting provider of ours where we host external websites,
so the query currently fails from our local caching server (127.0.0.1)
but not on 82.138.243.4 and 82.138.243.24 (our hosting providers dns
servers - will attempt to find our from them what they are running might
shed some light on things).
