Can you elaborate a bit more on this issue? What is the difference between a low pool for PPPoE and DHCP?
That may be implementation specific, or a reference to high IP rotation rates (which I like). PPPoE doesn't change it's IP as long as a connection is established. DHCP can change at the half life of the lease time. In my case, end systems which are currently busy will hold their lease in 10 minute intervals (I think it's 10) until that transmission is complete, and then it will renew to the new IP. There were a few legacy systems which didn't like changing IPs with 1 hour leases, but those are now obsolete and I haven't heard of a problem in years.
I expect new IPv6 support on CPEs to return to the old days of being horribly broken and have to work their way up to sanely handling renumbering (especially with DHCPv6-PD).
