No more “Various Registries”

by Leo Vegoda on February 27, 2008

Last week we improved the format of the IANA IPv4 Address Space Registry. It is now much easier to see which address space is available for allocation to RIRs and which address space is reserved for Multicast and Future Use.

We made other changes, too. The IPv4 registry used to report that a lot of /8s were allocated to “Various Registries”. That wasn’t very helpful to anyone; it was a bit like saying “we don’t know”. In fact, the RIRs have been providing DNS and Whois services for addresses in these /8s but the IANA IPv4 registry didn’t indicate which RIR to consult because addresses in each of these /8s are often used by organisations in different RIR regions.

The RIRs and ICANN staff worked together to provide a more useful registry. Each of these /8s is now shown as “Administered by” one RIR. That RIR manages the reverse DNS for the /8 and provides a Whois service with a referral to the appropriate RIR when necessary.

We hope it’s much more useful and transparent than before.

Maybe you can do something about the legacy names in the list, like “AT&T Bell Laboratories” (that’s about 16 mergers and divestitures ago – who actually controls 012/8?), not to mention Digital Equipment Corp and “Bell-Northern Research”.

When you reported that a network that had been returned from BBN I asked them why they would do this and they insisted that it wasn’t theirs and they didn’t return it.

Larry,

That’s the next phase. We’re want to improve the registration records for the legacy former Class A assignments, too. I hope that we’ll be able to update those registrations soon, so that the information is more useful than it is right now.

I know that the IPv4 registry isn’t perfect yet but I hope it’s moving in the right direction.

Leo
