They floated the idea of a /8 dedicated to VPNs, but it didn't go anywhere (we at IANA told them to bring it up with the IETF -- not sure if they ever did). > now actively being allocated by LIRs in Europe.

You would think that after a number of years they could've come up with a better solution than to use different squat space. Given 25/8 is 'legacy' space, unencumbered by registration service agreements, I suspect folks using Hamachi for v4 VPNs will get another unpleasant surprise in the future. Regards, -drc
A Splendid Example Of A Renumbering Disaster
It's Friday. Time to plug IPv6 some more. :-) http://b.logme.in/2012/11/07/changes-to-hamachi-on-november-19th/ LogMeIn Hamachi is basically a NAT-traversing layer 2 VPN solution. They avoided conflicts with RFC 1918 space by hijacking IPv4 space in 5/8, now actively being allocated by LIRs in Europe. When that didn't work (see link above), they moved to 25/8, allocated to the UK MoD. While I'm almost sure that they haven't got it quite so wrong this time, following the comments says that the idea was not only a very bad one to start with, it's cost a lot of people a lot of grief that IPv6 was clearly going to mitigate in renumbering. Perhaps it is why they recommend it per default, if not for the number of applications that would be broken by it. By the way, is this an application that the new shared transition space might benefit? Cheers, Sabahattin
