Has anyone come across massive outbound traffic from your users connecting to 192.175.48.1,192.175.48.42,192.175.48.6 via port 53?
Is it ok to block these traffic?
Pls advice.

These addresses are from prisoner.iana.org, which are somethin called as blackhole servers. you dont need access to these servers on port 53.. block them..
