i can show the auth data I have, the (to me) data from large caches is suggested in places like OARC and elsewhere that suggest caching is a huge factor is the scaling of the DNS. I've been flogging the idea that it would be an excellent idea to correlate data flows between stub/cache/auth servers and maybe have a couple of interested parties. if your doing similar work, we should talk in a more restricted setting. > >> oh... leakage into the public DNS means that the root nameservers have >> to be >> over-provisioned by a couple orders of magnitude to deal with the crap >> that should >> be in private space but leaked out and can't be resolved. > > I thought the (vast) over-provisioning of the root servers was to cope with > DDoS attacks. this (leaking) is a DDoS... :) -- bill > > Regards, > -drc > _______________________________________________ Ietf mailing list Ietf@ietf.org https://www.ietf.org/mailman/listinfo/ietf
