You prefix the IP address in reverse order to the domain. The query is e.g.

99.39.133.195.dnsbl-1.uceprotect.net. IN A

to look up 195.133.39.99

If listed. the A record would be 127.0.0.{1,2,3, ...}

And the meaning of the last octet is locally defined by the specific DNSBL.

You can often get additional details by also getting a TXT record.
