Comment 8 for bug 1090593

An SRU into existing releases makes good sense. The change is very minimal, with the biggest risk being that somepoint after the current operator of D stops using the IP address, said address gets assigned to someone who decides that giving out the wrong answers would be a thing to do. I don't see that as even remotely likely.

As for what the issue actually causes: it slows down lookups a very very small fraction of the time, since BIND does round-trip time tracking on requests, and prefers hosts that answer faster, and rarely queries the root nameservers (most TLDs are 2 day TTLs) in any case.
