ebersman> IPv4 reachable traditional DNS servers for some tiny group of ebersman> antique folks will be needed for years, even if we get 99+% of ebersman> the world to some new system.
mallman> I wonder if we're ever allowed to just decide this sort of mallman> thing is ridiculous old shit and for lots of reasons we can and mallman> should just garbage collect it away. We aren't allowed as IETF/engineers. The world sort of is. ;) Eventually, someone wonders why they're burning money on something they don't see a need for any more. Sadly, based on the number of IBM AS400s in service, the COBOL programs with no source still being used, SNA, X.25 and all sorts of other stuff that you'd think would have been dead decades ago, I'm not betting on this happening any time soon. mallman> To me, this whole notion is that we can in fact get rid of this mallman> giant network service. If we don't get rid of it then what is mallman> the incentive to move one's own resolver away from using the mallman> root nameservers? But what would we replace it with? Who would run it? How would we get uniqueness, data integrity, high availability, decent coherence? How would we get something the entire world would use? Part of why DNS is so abused and misused is that it's already here and it mostly scales/works. We did it before the world knew about the internet. Now there's way more attention, money, and politics that get in the way of truly massive changes. If DNS started from scratch today, it's not clear it would happen. Not saying it's impossible but it will be a daunting task and will have to be really really compelling (or be the next user loved shiny-ball/Pokemon). Look at how much fun and progress there is moving from IPv4 to IPv6. mallman> Maybe 99% lets us draw down the size of the root mallman> infrastructure...I dunno. But, if we don't say something like mallman> "it's going to go away" then I am not sure resolvers will move mallman> away from it. The problem/load isn't the folks that would upgrade. It's crap broken code/devices that are in many cases forgotten in closets or under desks. The magic blue smoke will have to pour out the back before they stop sending useless crap to the root servers. A6 records were never officially "blessed". We went with AAAA. We were all pretty sure they would never be used. But last I heard, the root servers still see A6 queries. Google for Geoff Huston's zombie DNS preso for more scary/bad stories. Love to see your proposal for a replacement. Just be prepared to have to support whatever that is and DNS both for a very long time. _______________________________________________ dns-operations mailing list dns-operations@lists.dns-oarc.net https://lists.dns-oarc.net/mailman/listinfo/dns-operations
