Hi, Karsten. ] I think, having the bogon list as route-set in any of the IRR ] databases, say whois.radb.net would be very helpful to process ] this list with peval. Funny you should mention that! :D The fine folks at Merit donated a maintainer object, MAINT-BOGON-FILTERS, to me for this very purpose. I have created three filter-sets that are in BETA status until I have a few more folks review them. They are: fltr-unallocated - The unallocated (by IANA) IPv4 prefixes. fltr-martian - The special use and reserved IPv4 prefixes. fltr-bogons - fltr-unallocated + fltr-martian. These filter-sets will be updated as regularly and as quickly as my other bogon monitoring and templates. I will PGP sign them so that folks can verify the updates (my key is available on my web site and on the MIT key server). Please take a look and let me know what you think. Feedback and suggestions are very welcome! Thanks! Rob. -- Rob Thomas http://www.cymru.com ASSERT(coffee != empty);
