I am pretty sure that I mentioned that... :(
If you don't create an account, just using their DNS server alone is the 'no frills' version...is it not?
AFAIK, what you get with the "no account" IP addresses defaults to "error correcting redirection"; i.e., you type in 'microsoft.con' and you don't get a 'server doesn't exist' error.
Compare:
C:\Documents and Settings\User>nslookup microsoft.con 208.67.222.222
Server: resolver1.opendns.com
Address: 208.67.222.222
Non-authoritative answer:
Name: microsoft.con.aosake.net
Address: 208.67.219.130
With:
C:\Documents and Settings\User>nslookup microsoft.con dnsr1.sbcglobal.net
Server: dnsr1.sbcglobal.net
Address: 68.94.156.1
*** dnsr1.sbcglobal.net can't find microsoft.con: Non-existent domain
The last one is "no frills".
