# port The port number in host byte order. ``` var port: UInt16 { get } ``` ## Discussion Inspects the underlying storage’s `ss_family` and reads `sin_port` or `sin6_port` accordingly, converting from network byte order (big-endian) back to host byte order. Returns `0` if the address family is neither `AF_INET` nor `AF_INET6` — a defensive fallback that should not occur for addresses produced by this API.
