Question:

When uploading a master list to a custom category, what is the IP Lookup option used for?

Reply:

If you select “Upload the file with IP Lookup”, then R3000 will query Internet domain name servers for each valid URL in your list. Basically it will run an nslookup query for each URL in your list and if it is able to resolve to an IP address, it will add that IP address to your custom category's Master List. The result of this will be filtering will take place by IP address as well. So if the custom category is set to a Block List, then IP addresses that correspond to URLs in the uploaded file will be blocked along with the URLs. Conversely, if the custom category is set to an Allow List, then IP addresses that correspond to URLs in the uploaded file will be allowed along with the URLs.
