While I believe people SHOULD be providing INADDR service, the people hurt 
by refusing connections are rarely the ones who have any influence. Just as 
Network Address Translation is not a security solution, neither is checking 
INADDR. Now if you check INADDR over Secure DNS, you might start having 
some level of information to trust.

Well, this engineer also has customers to take care of. Those customers 
cannot easily influence ATT Broadband or ATT Wireless to do things "right". 
So, I choose to keep having customers rather than closing down my business 
over others not having INADDR.

Please explain how a customer changes to another broadband vendor, or 
another CDPD vendor. Despite your company's presence in a limited number of 
markets, there are MANY people out there with only one choice (if they're 
lucky) for broadband. I'd be more likely to lose a customer than get them 
to change ISPs.
