This DHCP is too dynamic

[Adam Myrow]

As I understand it, PPPOE works much like dial-up.  That is, it requires a
username and password before connecting you.  It then gets a dynamic IP
address and stays with that address until you disconnect.  I'm wondering
if perhaps the user of PPPOE is disconnecting every few minutes or if the
ISP is kicking him off?  As long as he's connected, he should not change
IP addresses.  As an aside, I use DHCP with my Roadrunner cable and have
been getting the same IP address since day 1.  DHCP, at least under Linux,
stores your previous IP address and requests it the next time you connect.
If it is available, it is used.  Otherwise, you get a new one.  Thus, DHCP
tends to be very stable if you leave your computer on for long periods as
I do.
