ipsocket.peeraddr([reverse_lookup]) => [address_family, port, hostname, numeric_address] Instance Public methods Returns the remote address as an array which contains address_family, port, hostname and numeric_address. It is defined for connection oriented socket such as TCPSocket. If reverse_lookup is true or :hostname, hostname is obtained from numeric_address using reverse lookup. Or if it is false, or :numeric, hostname is same as numeric_address. Or if it is nil or ommitte
