One reason I've avoided this solution is that I was told that the 
assigned IPAs where in the same ranges as the dynamic Comcast 
residential ranges, and thus get blocked by all kinds of blacklists. 
Not true?  Or now changed?

Another reason is that last time I checked, it was $100+/mo. for the 
biz. service.  That's more than double what I'm paying for residential 
DHCP.  Can you elaborate on this?

If I have residential Comcast Internet, with my own old but still works 
RCA cable modem, what's involved in switching?  I'd need 2 IPAs, one for 
the mail/DNS/web/etc. server and one for whatever else I was doing at 
the moment.

And yet another reason I haven't tried this is that Comcast has 
historically been totally unable to create or manage a robust DNS 
infrastructure.  To a large extent that doesn't matter, you simply use 
OpenDNS or someone else.  Any issues here?

Interestingly, we had this discussion a little over a year ago:, 
with at least one pretty negative comment: 
Have things really improved that much?  (Perhaps competition is a 
wonderful thing? :-)
