RE: [UUG/MLUG] dynamic IP script

["Buford, Rick" <EMAIL:PROTECTED>]

I had problems with this when I was trying to run my box on DHCP...I know
that the IP was still "leased" to me, because doing an nslookup gave me the
same info, but my machine wouldn't get the same IP back if I shut it down
for anything. I gave up and went back to static IP and am trying to find
someone who can sneak a DNS entry in for me =)

   |Actually, I believe (or at least I've heard) that DHCP will 
   |try to give
   |you the same IP address you had previously when your lease 
   |runs out.  If
   |it CAN give it back to you, it will.  If not, you'll get a 
   |new one.  The
   |only way it's a big issue is if you are disconnected from 
   |the network for
   |an extended period of time.  Please correct me if I'm wrong.
