Unfortunately, there is no PON vendor in my area, so I live with com cast business (on a dynamic IP because I refuse to pay their absurd mark-up on IP addresses). Given a PON vendor in my neighborhood, I'd drop Comcast in a heartbeat.

The whole idea that DHCP should only be used for (and is absolute proof
of the status of) despised-class customers is just nuts.

When I was a network administrator we were working to convert all hosts
to DHCP to improve the service to everybody.

There were some hosts that were not bright enough to use DHCP (I don't
remember an example, but I do remember there were some), it seems like
there were some where we decided it was a Bad Idea (see parenthetical
material above), and some that were not under our administrative control
who believed that to use DHCP was an admission of inferior status.

We had a lot of hosts that got their "permanently assigned", "static"
address via DHCP.

The big benefits came from being able to change name-server addresses,
default-gateway addresses (and even netmask settings although that
turned out not to work as well as we had hoped due to poor planning on
our part).

And of course, shortening the lease-life when changes were pending was
useful in the same way that changing DNS TTL is.
