Re: heads up on 80/8 [actually operational, so don't read this!!!]
| Several weeks old info. I am suprised that ICANN and or RIPE haven't made | the operational announcement to the NANOG or other lists. Not to invite a flamewar or anything, but it's not really an operational issue until some operator tries to route whatever they are allocated by the IRRs (RIPE, ARIN, APNIC). None of the IRRs (or ICANN) can really make ANY promise whatsoever that their allocations are globally routable. (This will be particularly true of ever-longer prefixes as they are allocated by various IRRs. IOW, who cares if the IRRs hand out /32s or /128s - just so long as people understand that the odds of global reachability in both steady state and during convergence [*] decrease roughly proportionally to the length of the prefix). So, this could well have been the first time an operator has found an operational issue with 80/8 that is relevant to the NANOG audience. :-) | Thanks for posting it to NANOG You're very welcome - hey, first public-act-of-smd in many days.

While I could agree that its not a problem till someone tries to use it, I point out that ARIN does make an announcement when they are going to start issuing from a new IANA block. We, The Net Operators, should have this information so that we can update our filters, should we see fit to, and thus cause as little negative impact as possible. Several of the sample filters I have seen just drop anything that is currently NOT in the IRR space, otherwords the IANA reserved spaces, like 80/8 ******* In fact if I remember correctly from the recent RIPE-39 meeting, its 80/7 that they will be alloc'n from. ******* On Wed, May 16, 2001 at 08:15:45AM -0700, Sean M.

And I'll counter-point out that ARIN is notifying relevant groups in its Region. Why would you expect the RIPE NCC to formally notify a group (nanog) that is not in its region (Europe) ? To keep this operational, this lists the various /8s and who is (nominally) in charge of 'em; it may be of interest to people who haven't reviewed their filters in ages: http://www.iana.org/assignments/ipv4-address-space

no reason at all. after all, why would europeans want north americans to relax our filters so that routability to europe was maintained? randy
I can't for the life of me find anything on the web about RIPE recieving or allocating from 80/7 ... google has failed me. Can someone in RIPEland let some of us north americans know where announcements of new RIPE allocations are made? I'll happily forward any email notification to NANOG, as I'm sure many others would, but where does the initial announcement get sent? I'm sure many of us would like to update our prefix filters in a timely fashion. Cheers. -travis
