Back when I was running IANA and we noticed this (back in 2006 or so -- don't remember the exact dates), we suggested to the folks at Hamachi that using squat space was perhaps not the best idea. 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. When that didn't work (see > link above), they moved to 25/8, allocated to the UK MoD. Sigh. 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
