Both TCP and UDP use an unsigned 16-bit integer to designate port number. I don't imagine any implementation in any operating system is going to be able to open more than 65535 sockets per bound address at best.

If that is the case, it would be a Windows network architecture limit instead of a soft, configurable limit.
