[Personal Opinion Mode ON]
I would find it rude, especially given the expertise required to set up NAT
on a demand-dial Firewall, a reason like "I can't post the IP address"
stretches the limit of credibility, when one-command ("ifconfig ppp0 | mail
[EMAIL PROTECTED]") in your demand-dial script file should do the trick...
If someone gave me *that* excuse for scanning 4 class C's... :-)
But I do get your example though. I'm sure that somewhere out there is an
application, which hasn't heard of the concept of directory services, which
needs to scan a collective subnet for a response (not counting broadcasts a
la NetBIOS/XDMCP). I just can't really think of one. Oh wait,
BackOrifice2000... :-)
No snarkiness intended...
