[dns-operations] Inconsistent b.root-servers.net responses for 1.0.0.127.in-addr.arpa

[Noah Treuhaft]

B.root-servers.net's responses to 1.0.0.127.in-addr.arpa/PTR/IN
queries are a mixture of NXDOMAINs and this:

;; ANSWER SECTION:
1.0.0.127.in-addr.arpa. 99999999 IN     PTR     LOCALHOST.

;; AUTHORITY SECTION:
0.0.127.in-addr.arpa.   3600000 IN      NS      b.root-servers.net.

;; ADDITIONAL SECTION:
b.root-servers.net.     3600000 IN      A       192.228.79.201

That's not intentional, is it?
