This is basically publishing an SRV record saying where the WHOIS
server is. E.g:
wkumari-macbookpro1:tmp wkumari$ dig SRV _nicname._tcp.nz

; <<>> DiG 9.9.4rc2 <<>> SRV _nicname._tcp.nz

There are a number of ccTLDs that publish these (37).
Unfortunately new gTLDs are prohibited from doing this, for a bunch of
silly policy reasons (I tried to get this changed, but there was
enough stupid here that I gave up).
