You should move 192.88.99.0/24 from SPECIAL to YES (although you
shouldn't see source addresses from that prefix, no matter what the
folks at bit.nl think). 169.254.0.0/16 should be NO (otherwise it
wouldn't be link-local).
to make the list more future-proof, listing 128.0.0.0/16,
191.255.0.0/16, 192.0.0.0/24 and 223.255.255.0/24 as YES might be a
good idea. I'm not sure what to do with 39/8.
I haven't looked at RFC 3330, but another RFC reserves 192.0.2.0/24
for examples in documentation. In practice, this prefix is used for
distributing fake null routes over BGP, so it's a rather strong NO.
