BUTT, root servers are NOT recursive or caching, they serve a very small limitited set of data that changes at low frequency (I am not sure of the current rate of updates, but it use to be only once daily.) Anyone can bring up there own replicate of a root server locally, I do, and have for 2 decades, its a rather trivial thing to setup and maintain. But unlike a root, I also turn on recursision and caching. Again IMHO, a caching recursive any cast server ala 8.8.8.8 would be far more useful than just a stock "root server." > -- > AMA March 31: https://www.broadband.io/c/broadband-grant-events/dave-taht > Dave T?ht CEO, TekLibre, LLC -- Rod Grimes [email protected] _______________________________________________ Starlink mailing list [email protected] https://lists.bufferbloat.net/listinfo/starlink
