I've gotten a lot of hacker wannabes and spammers using IPs associated with IPXO and have started blocking their IP ranges when I come across them.
Today I had a user that was unable to get to the site because she's using a VPN that apparently uses one of IPXO's ranges. Sure enough, I had the /16 block on my blacklist (lots of other bad actors in that range as well).
What's been your experiences with traffic from IPXO ranges?
