The Department of Work and Pensions, UK has an entire /8
by Eugen Leitl 28 Sep '12

http://paritynews.com/network/item/325-department-of-work-and-pensions-uk-i… Department of Work and Pensions UK in Possession of 16.9 Million Unused IPv4 Addresses Written by Ravi Mandalia Department of Work and Pensions UK in Possession of 16.9 Million Unused IPv4 Addresses The Department of Work and Pensions, UK has an entire block of '/8' IPv4 addresses that is unused and an e-petition has been filed in this regards asking the DWP to sell it off thus easing off the RIPE IPv4 address space scarcity a little. John Graham-Cumming, who found this unused block, wrote in a blog post that the DWP was in possession of 51.0.0.0/8 IPv4 addresses. According to Cumming, these 16.9 million IP addresses are unused at the moment and he derived this conclusion by doing a check in the ASN database. “A check of the ASN database will show that there are no networks for that block of addresses,” he wrote. An e-petition has been filed in this regards. “It has recently come to light that the Department for Work and Pensions has its own allocated block of 16,777,216 addresses (commonly referred to as a /8), covering 51.0.0.0 to 51.255.255.255”, reads the petition. The UK government, if it sells off this /8 block, could end up getting £1 billion mark. “£1 billion of low-effort extra cash would be a very nice thing to throw at our deficit,” read the petition. Cumming ends his post with the remark, “So, Mr. Cameron, I'll accept a 10% finder's fee if you dispose of this asset :-)”.

Apologies, as this was discussed recently. There was an engineer from Charter Business who was setting up IPv6 trials for Charter Business customers recently. If he is still lurking the list, can I ask that you contact me off-list to discuss this? Thank You. Dale Elfes

Ethernet OAM BCPs Please are there any yet???
by Adam Vitkovsky 27 Sep '12

27 Sep '12

Hi Are there any best common practices for the CFM levels use Since my pure Ethernet aggregation layers are small I believe I only need two CFM levels I plan on using Level 5 between CPEs managed by us and Level 4 between Aggregation devices -that's where MPLS PWs kicks in So leaving Level 7 and Level 6 for customers and carrier-customers respectfully -would this be enough please? I'm also interested on what's the rule of thumb for CCMs Frequency, Number of Packets, Interpacket Interval, Packet Size and Lifetime for the particular operation Thanks a lot for any inputs adam

Re: is CERNET part of the Internet?

In 2001 I'd the pleasure of working with CNNIC in the IETF technical and ICANN policy areas. At the time a bug in the UTF8 processing in the then-prevelant version of IE yeilded packet sequences originating from the edge device, on a IP block in the PRC (and elsewhere resolution was attempted of labels in the Han Script input into in the IE navigation field) to IP addresses allocated to Microsoft, to IP addresses allocated to an "IDN Solutions Vendor" in Silicon Valley, and to IP addresses allocated to Verisign Registry. As there were a non-trivial number of instances of IE with this bug operating in the PRC in 2001, the aggregate of these several packets per string per IE instance had a non-trivial overseas bandwidth cost -- settled at the time in hard currency, USD -- a scarce resource at the time. I suggest that (a) substituting whatever one has as "the definition" of "the Internet" for settlement free peering is suspect, and (b) the cost of overseas bandwidth in the PRC is still non-negligible, and (c) the cost, when amortized over cache instances, may be less than the cost of cost recovery, and offered as "free", and (d) the cost of uncacheable traffic cannot be so amortized, and (e) while USD are not a scarce resource in the PRC at present, settlements may still be made in currency other then RMB.
