Well we as root-server operator will have to take the costs of upgrading to handle the total query volume....10-15% is then quite a lot. > > > | I read a report that only 2% of the hits on the root servers is both > | legitimate and useful anyway. > > ~From the presentation I refer to which unfortunately is in Swedish but > you can probably read the numbers anyway... : > > http://www.iis.se/Internetdagarna/2003/23-robust-dns/id03-23-lars- > johanliman.pdf > > this is clearly not the case.

The 2% figure I think was from an analysis of f.root-servers.net. i.root-servers.net seems to be seeing more "valid" queries than f. I guess these figures are different from each server. I think Liman said that we where seeing 25% garbage in total. I think queries from and about RFC1918 addresses was around 20% of those. It would be fun to see what percentage of the Ipv6 related queries that are for site-local addresses... - - kurtis - -----BEGIN PGP SIGNATURE----- Version: PGP 8.0.2 iQA/AwUBP4f0L6arNKXTPFCVEQLr0wCfQ98s0IuFlle09q5Ceu41dzxY0ncAoMde WOPfR47J5gKXQbD85232h5YK =uMUn -----END PGP SIGNATURE-----
