I have been investigating Fast-Flux service for a while, and sometimes I
need to retrieve WHOIS data from different TLDs.

Today, I was looking for .CO.NZ data, however every query I sent, I got
permission denied. I am not sure if this block is based on my IP current
geolocation (Brazil), but when I ask from different locations such as US
and UK, I can have this data.

I tried different sources in Brazil, São Paulo and Rio de Janeiro, for

Is there any RFC or other documentation that says that a TLD (whois in this
case) can deny requests based on IP Geolocation?
