def _resolveIPv6(ip, port): (source)

Resolve an IPv6 literal into an IPv6 address.

This is necessary to resolve any embedded scope identifiers to the relevant sin6_scope_id for use with socket.connect(), socket.listen(), or socket.bind(); see RFC 3493 for more information.

Parameters	ip	An IPv6 address literal. (type: `str`)
	port	A port number. (type: `int`)
Returns	a 4-tuple of `(host, port, flow, scope)`, suitable for use as an IPv6 address.
Raises	socket.gaierror	if either the IP or port is not numeric as it should be.
