	DS-Query in the parent zone sends valid NSEC3 RR with the Hash "vprhdrfsgvoci6msqok112vtf4msq4k4" as Owner. That's the Hash of "bandstraat4.nl" with the NextHashedOwnerName "1vn8ueh4bnsrnl4o02m3cl0j4uvrjnfs". So that domain name is the Closest Encloser of "mqtt.bandstraat4.nl". Opt-Out: False.

	DS-Query in the parent zone sends valid NSEC3 RR with the Hash "ans0kntv377q0gteebq89s5d2obc6dar" as Owner. That's the Hash of "mqtt.bandstraat4.nl" with the NextHashedOwnerName "bm3fn0oqtnru2qf37pso0o45nt5j04tk". So that domain name is the Closest Encloser of "www.mqtt.bandstraat4.nl". Opt-Out: False.

	The ClosestEncloser says, that "*.mqtt.bandstraat4.nl" with the Hash "set6uevkiu2bl4agvhfhacl65412dv4o" is a possible Wildcard of the DS Query Name. But the DS-Query in the parent zone sends a valid NSEC3 RR With the owner "rpv3f30pdfvb3cdmbbdgn22r3odtl6mp" and the Next Owner "sps5sqhmbc7l85gv4n6hrqaja8o6th1v", so the Hash of the wildcard is between these hashes. So that NSEC3 proves the Not-existence of that wildcard expansion. Opt-Out: False.

	4. Content- and Performance-critical Checks
A	Good: Domainname is not on the "Specially Designated Nationals And Blocked Persons List" (SDN). That's an US-list of individuals and companies owned or controlled by, or acting for or on behalf of, targeted countries. It also lists individuals, groups, and entities, such as terrorists and narcotics traffickers designated under programs that are not country-specific. Collectively, such individuals and companies are called "Specially Designated Nationals" or "SDNs." Their assets are blocked and U.S. persons are generally prohibited from dealing with them. So if a domain name is on that list, it's impossible to create a Letsencrypt certificate with that domain name. Check the list manual - https://www.treasury.gov/resource-center/sanctions/sdn-list/pages/default.aspx
