NANOG23 DNS broken, again

Bah, why does this seem to happen at every NANOG conference?

Looks like someone has just put in the reverse DNS for the NANOG network
IP addresses, but not put in forward DNS. This breaks tcp_wrappers.

Can someone fix?

Looks okay to me, eg:

[philip@pfs-pc philip]$ dig -x 65.174.251.254

;; ANSWER SECTION:
254.251.174.65.in-addr.arpa. 86400 IN PTR infra-251-254.nanog23.merit.net.

[philip@pfs-pc philip]$ dig infra-251-254.nanog23.merit.net

;; ANSWER SECTION:
infra-251-254.nanog23.merit.net. 3600 IN A 65.174.251.254

Was there a particular example you have?
