comcast dhcp leases

[me at mattgillen.net (Matthew Gillen)]

Has anyone else noticed that Comcast's lease times for dhcp addresses has
gone down significantly?  The lease time used to be on the order of days at
a time.  I was able to keep the same IP address for 2 years, even with
several extended downtimes for upgrades to my server box.

Recently, the lease time is less than an hour.  Anyone have ideas on why
they would do that?

Or is it just me?

Matt
