Hi, OK, here's a follow-up: in fact I was wrong. Maybe it took a couple
of logins to "stabilize" or perhaps the observations I made were
distorted by haste, fatigue, etc. -- all those factors that come into
play when struggling with myriad unfamiliar issues on a new OS
installation -- but in any case, my Adelphia ip assignment (under DHCP)
has "stabilized" and is now the same each time, as the M$Doze client
experiences -- although it is of course NOT the same ip I got when
starting the M$Doze environment.
Thanks much for your response, Andrew, it was helpful in that it nudged
me to look differently at the problem; but as an observation I'll
observe that there isn't any user command / flag / option that controls
whether dhclient "asks" for the same ip back again; unless it has
something to do with the complex options pertaining to DHCP lease expiry
duration or some such. dhclient just (now) seems to "do the right thing"
and asks for the same ip it had (== tries to use the last lease it had).
All is well, happy happy.
