I see a lot of information on reverse DNS, but I need an explanation of a definition.
Who is my ISP if...
I own a Web / Email server (apache2 / postfix / dovecot)
on a static IP (through comcast)
with DNS managed by GoDaddy (not BIND on the server)

In the situation you describe, your ISP is Comcast.
If you need a Reverse DNS entry, Comcast are the ones you need to contact.

Thank you. I have found no clarity on this at all with many hours and many times looking. I appreciate your patience and tolerance, sometimes a clear, straightforward definition is needed, and users like you (answering, rather than down-voting with no explanation) make this site great. – James Bailey Mar 14 '17 at 19:22
