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? :)
