Hi!
I have a server with a fixed IP adress in colo. It's through my job so I have full control of the dns-servers as well.
I recently bought a domain, so I could have a cool hostname on irc. But for some reason it won't work
At my domain provider I have these DNS records:
subdomain IN A 1.2.3.4
and on the DNS server responsible for the adress I have:
4.3.2.1.in-addr.arpa. IN PTR subdomain.domain.com
Am I missing something?

Try dig -x +trace ip.

Ok, here's the answer I got:
dig -x +trace 62.109.46.152
; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2 <<>> -x +trace 62.109.46.152

I'll include the output from nslookup at my adress as well:
nslookup 62.109.46.152
Server: 212.112.166.18
Address: 212.112.166.18#53
Non-authoritative answer:
152.46.109.62.in-addr.arpa name = is.a.hax0r.se.
Authoritative answers can be found from:
46.109.62.in-addr.arpa nameserver = b.ns.ip-only.net.
46.109.62.in-addr.arpa nameserver = a.ns.ip-only.net.
46.109.62.in-addr.arpa nameserver = c.ns.ip-only.net.
a.ns.ip-only.net internet address = 212.112.160.42
b.ns.ip-only.net internet address = 212.112.163.90
c.ns.ip-only.net internet address = 212.112.165.178

Well... that's really odd. It seems to work. Yet; no cool hostname in irc
It just shows my IP-adress as hostname:
/who dunz0r
dunz0r@62.109.46.152

RDNS is cached just like normal DNS. Wait for tomorrow.

You forward dns should match reverse dns. Some server may reject if not.
My dig show no result for hax0r.se yet.

Same here, reverse lookup ok but no forward. Double check your A records.
