  • ::/128Unspecified, 0.0.0.0
  • ::1/128 Loopback, 127.0.0.1
  • ::ffff/96 IPv4 mapped, e.g. ::ffff:192.0.2.47
  • fc00::/7 Unique Local Addresses (ULAs), RFC 4193, home or enterprise local, not routed over public internet, IPv4 equivalent of private or RFC 1918 address space, such as 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16
  • fe80::/10 Link-local Addresses, like 169.254.0.0/16
  • 2001:0000::/32 Teredo, IPv6 tunneling over IPv4 NATs
  • 2001:0002::/48 Benchmarking, reserved for use in documentation, should not be used, equivalent 192.18.0.0/15
  • 2001:0010::/28 Orchid, fixed-term experiment, only end to end basis routers should not see packets with these
  • 2002::/16 - 6to4 gw adds its IPv4 prefix to this range, creating a unique /48 prefix
  • 2001:db8::/32 - Documentation, examples, like 192.0.2.0/24, 198.51.100.0/24, 203.0.113.0/24
  • 2000::/3 - Global Unicast
  • ff00::/8 - Multicast, always as destination, never as source, like 224.0.0.0/24
