Some Pointers, Please

As a new user, I would appreciate pointers to the following questions.

With all of the various devices in our lives and looking at the dashboard, top clients section, I am able to click on the IP and view what is blocked or whitelisted, is there a method to have that show the hostname instead of ip addres? Much easier to determine the source of the producer.

Is there another method to search for items of interest, ie: nrc.tapas.net, other than using a search engine, that ties directly to Pi Hole? As it stands now, how I attempt to figure out whats good/bad, I select the item, and search duckduckgo.

Thanks

The first question was answered via searching this site, I needed to use the DHCP server option, and now am able to see host names instead of ip addresses.

Still researching the second Q

Regarding the second question, use a WHOIS site such as https://whois.icann.org/en to learn more about who owns the domain.
