Name Servers/IP Addresses

Hi,

Removing the IP address for nameservers in whois 
should not be a problem, as anyone who needs it
can obtain an accurate IP address for that zone
by doing a DNS lookup.  That's a much better method
as the IP address in DNS is what is actually used,
not whois.

The order of nameservers in the whois database should
also not be important, strictly speaking.  In DNS,
an NS record is an NS record.  There is no distintion
regarding NS records between master and slave name servers.
