The most useful Go package for creating TCP/IP applications is the net Go standard package. The net.Dial() function is used for connecting to a network as a client, and the net.Listen() function is used for accepting connections as a server. The first parameter of both functions is the network type, but this is where the similarities end.
For the net.Dial() function, the network type can be one of tcp, tcp4 (IPv4-only), tcp6 (IPv6-only), udp, udp4 (IPv4-only), udp6 (IPv6-only), ip, ip4 (IPv4-only), ip6 (IPv6-only), Unix, Unixgram, or Unixpacket. For the net.Listen() function, the first parameter can be one of tcp, tcp4, tcp6, Unix, or Unixpacket.
The return value of the net.Dial() function is of the net.Conn interface type, which implements the io.Reader and io.Writer interfaces! This means that you already know how to access the variables of the net...
