Addressing - Basics
128-bit identifier for interfaces or sets of interfaces
Addresses are assigned to interfaces, not nodes
Text representation of IPv6 addresses
- x:x:x:x:x:x:x:x where x is hex value of 16-bit piece of address
- fedc:ba98:7654:3210:fedc:ab98:7654:3210
- may compress strings of zeroes
- abcd:0:0:0:0:0:0:1234 == abcd::1234
- :: is the unspecified address (all zeroes)
- ::1 is the loopback address
Text representation of Address Prefixes
- IPv6-address/prefix-length
- fe80::/10
- fedc:ba98:7654:3210::/64
