/**
 * Normally, addresses have been represented using string addresses, like:

	tcp4://127.0.0.1:1234
	udp4://10.20.30.40:5060
	ws://1.2.3.4:5678
	tcp6://[1fff:0:a88:85a3::ac1f]:8001
	This isn't optimal. Instead, addresses should be formatted so:

	Binary format:

	(varint proto><n byte addr>)+
	<1 byte ipv4 code><4 byte ipv4 addr><1 byte udp code><2 byte udp port>
	<1 byte ipv6 code><16 byte ipv6 addr><1 byte tcp code><2 byte tcp port>

	String format:

	(/<addr str code>/<addr str rep>)+
	/ip4/<ipv4 str addr>/udp/<udp int port>
	/ip6/<ipv6 str addr>/tcp/<tcp int port>
 */
