I had the Perfect ranges tagged as VrtServer as of 2010. Thanks for the redesignation of ownership.
18.104.22.168/23 is part of Internap's /16 range but otherwise there were several Continuum ranges I didn't have.
The tzulo ranges seem to be designated "static" and to have individual rDNS per IP, which implies a static broadband.
