You remember correctly. How cable companies "enforced" this particular
ToS clause would very, but one tactic was to have short DHCP leases, and
guaranteee that the IP address would change at lease "renewal". To
counter, we got third-party Dynamic DNS service which would allow a
cable customer to periodically update the IP address of a domain, with a
short TTL so that a change would take effect immediately.
The other side of this: cable DNS servers would, on its own dime, cache
DNS lookups with week-long TTLs to thwart Dynamic DNS. It was quite a
war there for a while.
(N.B.: "we forced long TTLs to reduce the traffic necessary across our
peering points." At one point, the cable people said they had one,
count 'em one, peering link at 44 megabits/s, to serve all cable
companies [with their own internal network]. I still don't know whether
to buy that or not, and now it's moot.)
How did I know about the DNS server manipulation? I worked for a Web
hosting company with about 3,000 domains being served. Whenever the
company renumbered (until it finally got its own IP allocation in order
to multi-home) we would have to service the old addresses and new
addresses for a week. When the cable DNS servers finally aged out the
old addresses, we could shut down the old ones. Royal admin pain in the
Dunno if this is still true anymore.
