If that was

	89ab.567.4.3.7.1.0.4321.something

it would look okay, but as above it's definitely too lengthy.

I agree with many of the points John Klensin has mentionned.

For "addresses will frequently change", however, I guess (without
much in-depth knowledge) that while some addresses will indeed
change very frequently, others might me much more stable and
long-term, especially for example the addresses of some DNS
servers,... And it's these that have the greatest chance of
being used in URLs.
