RE: [UUG/MLUG] dynamic IP script

["Routier, Daniel J." <EMAIL:PROTECTED>]

Well, the ISP tracks your lease and tries to renew it on your computer every
(lease expire time)/2 or somewhere thereabouts, it's in the man.  So as long
as your computer stays online during ISP attempts to renew your lease, you
keep your IP (even if you shut off your computer between lease renewal
attempts).

Your ISP can also map your network address to receive a specific IP,
although that won't be terribly useful if you're dialling in and catching a
different modem each time, most likely.  A lot of ISP sell you static ip
option for some few bucks though, if you went to the trouble to get (pay
for?) a domain name then getting a static IP shouldn't be that tough?

My guess is what you want isn't quite possible.  I'm not sure, but I
_BELIEVE_ DHCP works by giving you an IP at "random".  Once you have it,
though, you usually keep it as long as your machine is up.  You could then
lose it when you took the interface down or shut the machine down.  I
think #2 isn't an issue.

If the reason you want a static IP is you want a domain name for it just
go to dyndns.org or any of the other free providers, they'll map a name to
your IP and at least dyndns.org offers clients that will automatically
update the hostname / ip pair whenever your address changes.
