Hello, I'm not sure if people are using the fltr-martian-v6 filter set maintained by Job Snijders: filter-set: fltr-martian-v6 descr: Current IPv6 martians mp-filter: { 0000::/8^+, # loopback, unspecified, v4-mapped 0200::/7^+, # Reserved by IETF [RFC4048] 2001::/32^-, # Teredo prefix [RFC4380] 2001:db8::/32^+, # NON-ROUTABLE range to be used for documentation purpose [RFC3849] 2002::/16^-, # 6to4 prefix [RFC3068] 3ffe::/16^+, # used for the 6bone but was returned [RFC5156] 5f00::/8^+, # used for the 6bone but was returned [RFC5156] fc00::/7^+, # Unique Local Unicast [RFC4193] fe80::/10^+, # Link Local Unicast [RFC4291] fec0::/10^+, # Reserved by IETF [RFC3879] ff00::/8^+ # Multicast [RFC4291] } I'm trying to figure out why prefixes like 0200::/7 or 0400::/6 are not included in this list Any ideas? cheers, Yannis
