[sclug] Odd behaviour from OpenDNS?

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.
