Hello, I'm seeing high number of reverse lookups on my DNS server coming from ARR servers. Each reverse lookup corresponds to IP address of incoming client. I have no idea what might be on server calling all those but I assume it has something to do with ARR
since addresses which are being looked up are incoming IP of individual HTTP clients on internet. Any ideas? G
ARR is functioning as a reverse proxy, so backend server will receive requests only from your arr server. If you want to backend server logs client ip instead of arr server ip, you can install arr helper:
Any chance you have IP and domain name restrictions enabled in IIS ?
No, just basic IIS installation, also this seems to be done after request has already finished executing since there is no delay in response to clients.
Just a complete guess based on your statement that this happens after the request is served , but have you configured anything like Advanced logging to do any kind of lookups.

Does ARR makes reverse lookup on each incoming IP address?

Hi,
