Interesting. They might have applied my idea draft of which was available in May. Or, they reached the same solution independently. Anyway, routing tricks does not solve a failure of DNS server on a host with perfectly working routing system. Thus, we need multiple IP addresses of DNS servers to try. Their proposal still increase the chance of survivability if DNS server is unreachable becasue of routing problems,though. > Perhaps the general principle of local address announcements for DNS > servers is useful enough that both aspects can be considered at once? As a demonstration to BGP-related WG on a possiblity to how to use BGP wisely, maybe. But, it is a bad idea to put everything into a single draft. I even avoided to put things on gTLD servers.
