IIS Question

By aspiring_one ·
Can someone explain to me how the reverse domain lookup works in IIS when you restrict access to sites by domains?

Also, why do you take a performance hit when you use it?

I try my best to answer.

When the client want to access particular website . IIS will check whether the IP address /the domain name (query the DNS server of ISP)is prohibited or not.

If yes. the website is access denied. If I wrong. Please point out

Domain lookup resolves domain names to IP addresses. Since your users supply an IP address, reverse domain lookup does the opposite, resolving their IP address to a domain name. If you have restricted XXX.COM from your site, each users IP address is checked to ensure that it is not registered to XXX.COM before allowing access to your site. The extra Internet communication required for your lookup accounts for the performance hit.
