keyplr - as I recall they all seemed, at the time, to belong to the same organisation. Looking again I see that the first half is (now?) Digital Ocean, which includes a cloud range so ipso facto is evil. :)
The second half is petersburgh. If you check DNS for (say) 126.96.36.199 then it returns the full /19 for petersburghinternet despite various /24 ranges saying otherwise.
wilderness - I was missing one of those - thanks. I have the two 208.116 ranges in a single Fortressx range of 188.8.131.52 - 184.108.40.206.
