Why they couldn't just allocate a single block is beyond me. :(

Add that OVH with Datapipe (now owned by Rackspace Cloud Hosting, 66.70.0.0/17) we can get the entire /16:

66.70.0.0 - 66.70.255.255
66.70.0.0/16

Thanks, keyplyr! It could have taken me a long time to put that together, srsly.

@keyplyr

That /16 has been on a radar on a few sites as of 2 month now...
