because IPv6 literals wouldn't work for the vast majority of users today? I do see links to URLs with IPv4 address literals. sometimes they're a good choice. but you're really missing the point, which is that DNS fails a lot. note that DNS failures aren't all with the authoritative servers - they're often with caches, resolver configuration, etc. Keith _______________________________________________ Ietf mailing list [email protected] https://www.ietf.org/mailman/listinfo/ietf
