There's an old thread on this [webmasterworld.com] by keyplr Vivid Hosting VIVID-HOSTING-4 192.154.192.0 - 192.154.255.255 192.154.192.0/18 VIVID-HOSTING-2 192.158.224.0 - 192.158.239.255 192.158.224.0/20 VIVID-HOSTING-3 198.37.96.0 - 198.37.127.255 198.37.96.0/19 VIVID-HOSTING-1 198.177.120.0 - 198.177.127.255 198.177.120.0/21 VIVID-HOSTING 199.188.88.0 - 199.188.95.255 199.188.88.0/21 VIVID-HOSTING-NET 209.133.107.128 - 209.133.107.255 209.133.107.128/25 MZIMA07-CUST-VIVID02 68.64.128.0 - 68.64.129.255 68.64.128.0/23 MZIMA07-CUST-VIVID01 68.64.136.0 - 68.64.137.255 68.64.136.0/23

So it appears the range I identified in that old thread:

68.64.128.0 - 68.64.191.255
68.64.128.0/18

is now operated by PacketExchange

As is this one:

68.64.128.0 - 68.64.191.255
68.64.128.0/18

And this is AboveNet:

209.133.0.0 - 209.133.127.255
209.133.0.0/17
