HP did the same for 15.0.0.0/8 and 16.0.0.0/8 until the HP/HPE split at which point I think they couldn't figure out who should get the address space. As 2 x /8

HP did the same for 15.0.0.0/8 and 16.0.0.0/8 until the HP/HPE split at which point I think they couldn't figure out who should get the address space. As 2 x /8 is pretty valuable, they sold off chunks of it and are presumably still doing so. Ironically, having such addresses was sort of useful when companies got acquired and teams got shifted around. Starting to use an acquired company's network that was never designed with "what if we get acquired and have to play nice with others" in mind causes all sorts of routing pain.
