This point is well taken, but sometimes the root zone is a useful test case for innovations that might be more generically useful later. It's relatively small, relatively static, *XFR accessible, signed but uses NSEC not NSEC3, etc. It's pleasantly free of annoyances. So, zone mirroring fell out of 7706, and I suspect it will eventually have broader applications than just local root cache. I think some of the early work on aggressive negative caching was root-specific as well. I wouldn't assume an idea is bad just because it's currently focused on the root, it might not always be. -- Evan Hunt -- [email protected] Internet Systems Consortium, Inc. _______________________________________________ DNSOP mailing list [email protected] https://www.ietf.org/mailman/listinfo/dnsop
