Description
Thirteen years ago Verisign renumbered j.root-servers.net so that it could be anycasted. Since that time, we have been continuing to answer queries sent to the old IP address. We have also been collecting some data on queries to old J-root.
In this presentation we will explore such questions as: what do we know about the clients of old J-root? Do they overlap with clients of the real J-root? Are there noticeable differences in traffic characteristics (e.g., EDNS, DNSSEC, query types) between the two? Does old J-root traffic fluctuate in the same way as real traffic? When real J-root gets attacked, does old J-root also get attacked? If so, can this be used to identify attacks coming through recursive name servers?
