The following bugs were fixed: * don't barf on pingable: and ping-hdl: attributes (RFC 5943). * don't barf on inet6num: assignment-size (RIPE policy proposal 2010-06). * RFC 5952 requires that ipv6 addresses be presented in lower case. * ipv6 addresses are now printed in optimised format. * added geoloc: and language: fields to both inetnum: and inet6num: objects. * compilation fixes for g++ 4.7 / debian wheeze. * stop talking asdot to IRRDBs. none of the IRRs supports asdot since ~2010. * silence a bunch of warnings for clang 3.0. * fix AS output for rpslcheck. Supported production targets for irrtoolset 5.0 include recent versions of: Debian / Ubuntu FreeBSD Solaris Mac OS/X The code will run on both 32 bit and 64 bit platforms. Please report any bugs to irrtoolset(a)lists.isc.org. Nick

Prefix Size Distribution in multiple flavors, on RIPEstat
by Vesna Manojlovic 07 Aug '12

07 Aug '12

Dear colleagues, thanks to the feedback we received after we've published the interactive widget for querying "RIR prefix size distribution" in RIPEstat, we created a follow-up: a dynamically updated web page that gives an overview of IPv4 address space prefix size distribution, per /8: https://stat.ripe.net/specials/registered-ipv4-prefix-size-distribution This page is updated once a day, and is based on statistics published by all 5 RIRs. Possible usage is general research about the distribution of address space, or prefix filtering based on minimum allocation size. If you want to query any other prefix size, and not only /8, or if you want to query for IPv6 space, here is the link to the widget: https://stat.ripe.net/widget/rir-prefix-size-distribution For the background, please find more information in RIPE Labs article about the widget: https://labs.ripe.net/Members/becha/rir-prefix-size-distribution-in-ripestat Looking forward to your comments or questions, regards, Vesna -- Vesna Manojlovic BECHA(a)ripe.net Senior Community Builder +31205354444 for Measurements Tools RIPE NCC http://ripe.net

IETF sidr meeting after RIPE65
by Rob Evans 03 Aug '12

03 Aug '12

Hi, If you haven't yet booked your return travel from Amsterdam for RIPE 65, and are interested in participating in such things, it may be worth noting that there will be an "interim" meeting of the IETF's sidr (Secure Inter-Domain Routing) working group at the same venue on September 29th, i.e. the day after the RIPE meeting finishes. This will be part of a Large Interim Meeting where several other working groups will also be present (although don't ask me which ones). Best regards, Rob
