Hi all, Our network is suspected to be infected by malware by the detector in upline network. Turns out that some of our developers use 1.1.1.1 as a "pinging testing". Google comes to my knowledge that 1.1.1.1 is not a private IP anymore? Since when? Also Google says 1.1.1.1 is well-known to be used by botnet command and control host?? I've blocked it in the local gateway. Just curious......
