IPv6
Martian IPv6 packets include bogons and those having source or destination addresses with the following special-use prefixes:
-
Address Block Present Use ::/128 Node-scoped unicast unspecified address ::1/128 Node-scoped unicast loopback address ::ffff:0:0/96 IPv4-mapped addresses ::/96 IPv4-compatible addresses 2001:10::/28 Overlay Routable Cryptographic Hash IDentifiers (ORCHID) 2001:db8::/32 Documentation prefix fc00::/7 Unique-local addresses (ULA) fe80::/10 Link-local unicast fec0::/10 Site-local Unicast (deprecated) ff00::/8 Multicast
6to4 is an IPv6 transition technology where the IPv6 address encodes the originating IPv4 address such that every IPv4 /32 has a corresponding, unique IPv6 /48 prefix. Because 6to4 relays use the encoded value for determining the end site of the 6to4 tunnel, 6to4 addresses corresponding to IPv4 martians are not routable and should never appear on the public internet. The 6to4 martians are as follows:
-
IPv4 Martian 6to4 Prefix 0.0.0.0/8 2002::/24 10.0.0.0/8 2002:a00::/24 127.0.0.0/8 2002:7f00::/24 169.254.0.0/16 2002:a9fe::/32 172.16.0.0/12 2002:ac10::/28 192.0.0.0/24 2002:c000::/40 192.0.2.0/24 2002:c000:200::/40 192.168.0.0/16 2002:c0a8::/32 198.18.0.0/15 2002:c612::/31 198.51.100.0/24 2002:c633:6400::/40 203.0.113.0/24 2002:cb00:7100::/40 224.0.0.0/4 2002:e000::/20 240.0.0.0/4 2002:f000::/20 255.255.255.255/32 2002:ffff:ffff::/48
Teredo is another IPv6 transition technology that encodes the originating IPv4 address in the IPv6 address. However, the encoding format encodes the Teredo server address and tunnel information before the IPv4 client address. Thus there is no definable set of prefixes more specific than 2001:0::/32 for Teredo packets with martian end-site addresses. It is, however, possible to spoof Teredo packets with the Teredo server IPv4 address set to a martian. The list of martian Teredo server address prefixes is as follows:
-
IPv4 Martian Teredo Server Address Prefix 0.0.0.0/8 2001::/40 10.0.0.0/8 2001:0:a00::/40 127.0.0.0/8 2001:0:7f00::/40 169.254.0.0/16 2001:0:a9fe::/48 172.16.0.0/12 2001:0:ac10::/44 192.0.0.0/24 2001:0:c000::/56 192.0.2.0/24 2001:0:c000:200::/56 192.168.0.0/16 2001:0:c0a8::/48 198.18.0.0/15 2001:0:c612::/47 198.51.100.0/24 2001:0:c633:6400::/56 203.0.113.0/24 2001:0:cb00:7100::/56 224.0.0.0/4 2001:0:e000::/36 240.0.0.0/4 2001:0:f000::/36 255.255.255.255/32 2001:0:ffff:ffff::/64
