I think these are all residential customers, as business customers
appear to use different subdomains and/or host naming conventions, e.g.:

	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
vs.
	70.88.25.201	70-88-25-201-chesterfield-va.hfc.comcastbusiness.net
	70.90.158.37	70-90-158-37-knoxville.hfc.comcastbusiness.net
	70.91.133.105	70-91-133-105-ma-ne.hfc.comcastbusiness.net

Or:
	23.240.176.98	cpe-23-240-176-98.socal.res.rr.com
	24.25.253.81	cpe-24-25-253-81.hawaii.res.rr.com
	24.27.121.156	cpe-24-27-121-156.tx.res.rr.com
vs.
	24.106.98.106	rrcs-24-106-98-106.central.biz.rr.com
	24.142.142.169	rrcs-24-142-142-169.central.biz.rr.com
	24.173.100.134	rrcs-24-173-100-134.sw.biz.rr.com

Those are all (very recent) direct-to-MX on port 25 spam sources, but it
looks to me like the first group in each set is residential and the second
group is business.  But perhaps I'm misinterpreting the naming.
