There are two caveats to be aware of which are documented in this
commit:
- Because the system will likely assign different ports when binding
several times to different address families, it is recommended to
only use a single address family, otherwise other nodes will only
get one port among the several that were assigned, possibly breaking
communication.
- AutoConnect won't work in this scenario, because it relies on the UDP
port being the same as the TCP port, which is not the case when using
system-assigned ports.
