That's great!  But what exactly does that mean... (C8

[rls@server]% nslookup www001.id.net
       Name:  www001.id.net
    Address:  199.125.2.11

[rls@server]% nslookup 199.125.2.11
       Name:    www001.id.net
    Address:  199.125.2.11

Forward/Reverse look right...  The 2.24 address is a virtual host on this
machine..  How exactly would I *fix* this DNS misconfiguration, and what
is misconfigured? :)
