Summary0000792: addition of non-routable IANA numbers as member domains
DescriptionA member can add a domain or, etc. These are reserved by IANA for local / non-routable purposes. Consequently, when doing a whois on these numbers, the results report IANA as the owner. When a ping check is launched, this results in a ticket in IANA's support system, which generates a standard response message back to support. Approximately one per month. Annoying to all.
Additional InformationIt is not entirely clear what the business case for delivering certs to local numbers is. They do provide some local security, but they are re-usable in other people's networks. Or, if being used, any other person can get one too by asking. So they are somewhat equivalent to self-signed certs.

There is a vociferous minority over at Mozilla that wants to ban them.

Proposed solution: disallow certs for IP addresses alltogether
