Windows IPv6 network no longer works

[Suall1969]

e1ed0c4 introduced a regression which prevents Windows nodes from joining IPv6 networks:

{"level":"info","addr":"wss://weron.up.railway.app/","time":"2024-09-04T12:36:21-07:00","message":"Connecting to signaler"}
{"level":"info","id":"[\"2001:db8::1/32\"]","time":"2024-09-04T12:36:27-07:00","message":"Connected to signaler"}
Error: Provided network(2001:db8::1/32) is not a valid IPv4 address

It appears to originate from the underlying TUN/TAP library.
