Re: do bogon filters still help?
* william elan net: > For those doing similar exercise, you might want to look at rephrased > version of rfc330 listed blocks: > http://www.completewhois.com/iana-ipv4-specialuse.txt You should move 22.214.171.124/24 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 126.96.36.199/16, 188.8.131.52/16, 192.0.0.0/24 and 184.108.40.206/24 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.
