I don't think so... Indeed, for our clients, i haven't configured 10.0.0.rev
zone in our DNS (i am using split view dns configuration and all our clients
queries are comming from: 10.0.x.0/24 subnets, where x = 1 up to 10),
but .... If you are right, why in the morning or in the afternoon, squid is
working ok?

no, we are in a vpn and for our internal IP address we are passing almost all
traffic... What's the name of squid directive which enable/disable ident

HOW CAN I TURN OFF DNS CHECKING IN SQUID ... log_fqdn directive is turned off
by default....
