IPv6 notation
- Leading zeros in each 16-bit group can be removed:
2001:0db8becomes2001:db8. - One run of zero groups can be replaced with
::. The longest run is preferred; ties go to the first run. - An IPv4-mapped address such as
::ffff:192.0.2.1is converted to hexadecimal groups for calculations. - The reverse-DNS name is built from the 32 hexadecimal nibbles in reverse order under
ip6.arpa.
