To check your current DNS Nameserver Settings please visit the following website and enter your domain name
On the results page right at the top you should see text similar to the following:
|Nameserver records returned by the parent servers are:|
|ns1.techservers.net. ['184.108.40.206'] [TTL=172800]|
|ns2.techservers.net. ['220.127.116.11'] [TTL=172800]|
If the nameservers returned mention '*.techservers.net', '*.kiwihosting.net.nz', '*.kiwigeeks.nz' (where the * will be something like ns1, ns2 etc) then your DNS is being hosted by KiwiGeeks, if none of these are present then your DNS is being hosted externally by a 3rd party.
