Hello, Thanks in advance for reading this.
I recently discovered OpenDNS and it's really amazing. One thing I'm still figuring out is how to block instance messaing app. it's simliar to Whatsap and my internal users are using it on both PC and Mobile and they seem to use many and different IP and ports to connect its server and I still don't know if it's possible to block it with OpenDNS.
