Just ran this command again and got different results than above:

C:\Windows\System32>nslookup -q=TXT mylocation.whois.dnscontest.cleanbrowsing.org 185.228.168.10
Server: adult-filter-dns.cleanbrowsing.org
Address: 185.228.168.10

DNS request timed out.
timeout was 2 seconds.
Non-authoritative answer:
mylocation.whois.dnscontest.cleanbrowsing.org text =

“CleanBrowsing: dns-edge-usa-east-chicago-c, 185.228.168.168”
