I am using python WSGI module for servicing IPv4 http requests. Does WGSI support IPv6 requests? Can it listen to IPv6 IP port combination?
WSGI is completely unconcerned with IP versions; it is a specification for communication between a webserver and Python code. It is up to your server - Apache, nginx, gunicorn, uwsgi, whatever - to listen to the port.
Does python WSGI supports IPv6?
