DNS ISP Host List Available

[Marc Perkel]

I've also created a DNS based list of domains that provide consumer 
dynamic IP address space. I'm using this list internally but thought I'd 
make it public in case others can use it.

Trying to inspire innovation.
Example:

dig comcast.com.isphosts.junkemailfilter.com

This list was created by grabbing the registry barrier part of the 
domain name of IPs from other DNS lists that list the IPs as dynamic.
