Victor,

NAT translate the DNS A and PTR lookups

I haven’t seen a command that will disable just the DNS translation, but you might be able to achieve your goals by explicitly denying the DNS server address in your NAT access list.

Not applicable

I think there is a command that will disable DNS translation, that will be entered in global configuration mode ( no ip domain-lookup)
