I kicked verizon and its 50+ year old buried cable to the back fence and 
went to the local cable for both phone and net 15+ years ago, Shentel 
assigns ipv4's acc the mac of the router requesting a connection, so 
I've been cloning router mac's for at least that long, and so dependably 
that the link in my sig is in the middle of its 4th renewal at namecheap.

Cheers, Gene Heskett.
