Hi,
I've not really looked in to OpenDNS. I don't use it but was using a host that uses OpenDNS servers.
If you are using OpenDNS then doing an nslookup for an no existent host returns a valid IP address.
Example:-
$ nslookup zzpluralalpha.co.uk
Server: 208.67.222.222
Address: 208.67.222.222#53
Non-authoritative answer:
Name: zzpluralalpha.co.uk
Address: 67.215.65.132
If I use the google nameserver I get
$ nslookup zzpluralalpha.co.uk. 8.8.8.8
Server: 8.8.8.8
Address: 8.8.8.8#53
** server can't find zzpluralalpha.co.uk.: NXDOMAIN
What is the general consensus on OpenDNS?
Tom.
