pkg will communicate with a repository over a network using one or more
of a number of different protocols, depending on how it is configured.
Those protocols include:

   HTTPS
   HTTP
   FTP
   FTPS
   SSH
   NFS

Each of these have well-known port numbers, but, again, depending on
configuration some of these can be overridden to arbitrary port numbers
if required.

Hint: use 'pkg -vv' and look for the 'url' field in the repo.conf

If the URL scheme is 'pkg+something' that indicates a SRV-style lookup,
which can override the normal port numbers, as can an explicitly given
port in a http://example.com:8080/ style URL.

However, if you're using the default /etc/pkg/FreeBSD.conf, then the
communication protocol is HTTP over port 80.
