For those doing similar exercise, you might want to look at rephrased
version of rfc330 listed blocks:
You should move 18.104.22.168/24 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 22.214.171.124/16,
126.96.36.199/16, 192.0.0.0/24 and 188.8.131.52/24 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.
