Hostnaming is not always straightforward, as there are variations of
commercial service (some with static IPs, others with dynamic, some
enterprise, branch office, SMB, etc.).

FWIW:
24.7.48.153	c-24-7-48-153.hsd1.ca.comcast.net
	24.10.217.142	c-24-10-217-142.hsd1.ut.comcast.net
	24.129.85.220	c-24-129-85-220.hsd1.fl.comcast.net


Are all SMB customers.
