New IPv4 blocks allocated to RIPE NCC

11 May '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [Apologies for duplicate mails] Dear Colleagues, The RIPE NCC received the IPv4 address ranges 31/8 and 176/8 from the IANA in May 2010. We will begin allocating from these ranges in the near future. The minimum allocation size for these two /8s has been set at /21. You may wish to adjust any filters you have in place accordingly. More information on the IP space administered by the RIPE NCC can be found on our web site at: <https://www.ripe.net/ripe/docs/ripe-ncc-managed-address-space.html> Additionally, please note that three "pilot" prefixes will be announced from each /8. The prefixes are: 31.0.0.0/16 31.1.0.0/21 31.1.24.0/24 176.0.0.0/16 176.1.0.0/21 176.1.24.0/24 They all originate in AS12654.

IPv6 Routing Recommendations
by Rob Evans 03 May '10

03 May '10

Thanks for the discussion so far, there seem to be a number of suggestions from the emails. First are a couple of comments that we go ahead with the document largely as-is. Second is the suggestion that we should keep a figure, but try and base it on a bit more science than "/36 sounds better than /40." Third is that any specific figure should be removed as it won't cover all cases. The third way is easy, and if consensus went in that direction, I am happy to cut the /36 figure out of the document, but then I'm struggling to understand why we would need a separate document to RIPE-399, which recommends aggregation, but accepts there are reasons you may have to advertise more specific prefixes. Would a modification to RIPE-399 that just expands on the cursory mention of "this all applies to IPv6 too," e.g. by adding a few IPv6 examples in the text, be sufficient? The reason the document was originally written was that once the routing requirement was removed from the IPv6 address policy document, there was pressure for the group to come up with a number that people could put in filters that allowed some flexibility with announcements of more specific routes within their /32, with a fair chance of those prefixes getting propagated widely, but limited the potential for abuse. If there is still need for a document separate to RIPE-399 (and of course that question is still open, but there have been some strong suggestions on the list that there should be), that brings us back to the first and second options. The first is a simplification of the second, so lets think about the second. Studying the IPv4 routing table may lead us to a potential number of more specific routes, but would it lead us to any conclusions about their length? The Swiss example shows that the routes may not be subdivided from the most significant bits of the prefixes, so how do we do the analysis? Remember, if this is to be a WG document, I'd like to attempt to reach consensus in the group (and I suspected that would never be easy), so all input is welcome! Looking forward to an interesting 20 minute discussion in Prague, Rob
