What's this?

getpeername() public

Returns the remote address of the socket as a sockaddr string.

TCPServer.open("127.0.0.1", 1440) {|serv|
  c = TCPSocket.new("127.0.0.1", 1440)
  s = serv.accept
  p s.getpeername #=> "\x02\x00\x82u\x7F\x00\x00\x01\x00\x00\x00\x00\x00\x00\x00\x00"
}

If Addrinfo object is preferred over the binary string, use BasicSocket#remote_address.
