t | ƒ f S( s Interpret a string as a host:port pair.
An IPv6 address MUST be escaped if accompanied by a port,
because otherwise ambiguity ensues: 2001:db8:85a3::8a2e:370:7334
means both [2001:db8:85a3::8a2e:370:7334] and
[2001:db8:85a3::8a2e:370]:7334.

This code figures out what source address would be used if some traffic
were to be sent out to some well known address on the Internet. In this
case, IP from RFC5737 is used, but the specific address does not
matter much. No traffic is actually sent.
