2.2.1. Preferred
x:x:x:x:x:x:x:x, where the 'x's are the hexadecimal values of the eight 16-bit pieces of the address.
Examples:
	FEDC:BA98:7654:3210:FEDC:BA98:7654:3210
	1080:0:0:0:8:800:200C:417A
Note that it is not necessary to write the leading zeros in an
individual field, but there must be at least one numeral in every
field (except for the case described in 2.2.2.).

2.2.2. Compressed
The use of "::" indicates multiple groups of 16-bits of zeros.
The "::" can only appear once in an address.  The "::" can also be
used to compress the leading and/or trailing zeros in an address.
	1080:0:0:0:8:800:200C:417A --> 1080::8:800:200C:417A
	FF01:0:0:0:0:0:0:101 --> FF01::101
	0:0:0:0:0:0:0:1 --> ::1
	0:0:0:0:0:0:0:0 --> ::

2.5.4 IPv6 Addresses with Embedded IPv4 Addresses
	IPv4-compatible IPv6 address (tunnel IPv6 packets over IPv4 routing infrastructures)
	::0:129.144.52.38
	IPv4-mapped IPv6 address (represent the addresses of IPv4-only nodes as IPv6 addresses)
