I should have asked explicitly: given my MAC address, how do I
determine the associated hostname? Can I ping it? Is there still a
fixed associated hostname on Comcast? A Google search yielded posts
that suggests Comcast might be changing their practices on that.

IIANM, your MAC address is only good for internal/local networks and
for comcast to identify your account. You are _not_ identified on the
net by your mac address. Your host/domain address resolves to a dotted
quad ###.###.###.### and this is used to identify you on the net/web.
The word names are a handy way of remembering place-names instead of
learning/remembering a string of disassociated numbers.
If you do not have a static address, your address changes periodically,
although it may not appear to. My address has been the
same for nearly two years, and I would prefer that it never changes.

Unlike what appears to be happening on ADSL, cable modem users tend to have long term dhcp leases.
