What’s “Prefer Hostname”?

There is an option in Rule -> Advance named Prefer Hostname. That’s allow the proxy to determine the IP instead of local result.

For example, when you want to access a.com, and it does not match any domain directives in the rules, it will be resolved by the local DNS. If the IP result matches an IP directive with the target set to PROXY, it will pass a.com to the proxy instead of using the locally resolved IP, provided that you have enabled this feature.
