The purpose of this article is to describe how the DNS process takes place in Explicit, Transparent and Reverse deployments

In Transparent deployments, the clients perform DNS lookups with their own configured DNS server/s in order to resolve the names into IPs before sending the requests to the proxy.

In Reverse deployments, lookups are performed under certain circumstances detailed in article TECH242768
