This was discussed in detail recently on the list, while you were posting
about BlenderCad, so I assumed you saw it?  You can go back in the archives
and see everyone's statements related to their Acceptable Use policy and
home servers if you like:

Cox does not allow incoming port 80 connections; you must use a URI
forwarder like DYNDNS.org or publish your URL via
http://$dynamicip:8008/index.html using the unique port of 8008 for
instance.  Apache or any web server can be configured to run on a
non-standard port.

Of particular note, Cox also does not, by their Acceptable Use agreement,
that we all contracted to abide by, allow "servers".  If they notice you
have a great many inbound packets for servers, they will set the dhcp lease
at one day.  Be warned, you are treading a grey--> red line here.

software clients exist for dynamic dns that will automatically update your
dns record when the lease expires and the ip changes.

FreeDNS, UltraDNS, dyndns.org all can do this, for varying fees in various
ways.
