Update network.go by revisiting #5134

Browse Source 
From the go source code on potential conflicts in IP Addressing schemes: https://cs.opensource.google/go/go/+/master:src/net/rawconn_unix_test.go
			// There's no guarantee that IP-level socket
			// options work well with dual stack sockets.
			// A simple solution would be to take a look
			// at the bound address to the raw connection
			// and to classify the address family of the
			// underlying socket by the bound address:
			//
			// - When IP.To16() != nil and IP.To4() == nil,
			//   we can assume that the raw connection
			//   consists of an IPv6 socket using only
			//   IPv6 addresses.
			//
			// - When IP.To16() == nil and IP.To4() != nil,
			//   the raw connection consists of an IPv4
			//   socket using only IPv4 addresses.
			//
			// - Otherwise, the raw connection is a dual
			//   stack socket, an IPv6 socket using IPv6
			//   addresses including IPv4-mapped or
			//   IPv4-embedded IPv6 addresses.
