I like the function avoid_martians(), and use it (mine's even been expanded a bit). I'd like to implement something similar for IPv6.
here you go:
function avoid_martians() prefix set martians; { martians = [ 0000::/8{8,128}, 0200::/7{7,128}, 2001::/32{32,128}, 2001:db8::/32{32,128}, 2002::/16{16,128}, 3ffe::/16{16,128}, 5f00::/8{8,128}, fc00::/7{7,128}, fe80::/10{10,128}, fec0::/10{10,128}, ff00::/8{8,128} ]; if net ~ martians then return true; return false; }
The above is not complete, but you get the gist of it, here is a more current overview in BIRD format: 0000::/8{8,128}, # loopback, unspecified, v4-mapped 0064:ff9b::/96{96,128}, # IPv4-IPv6 Translat.
