0 DS RR in the parent zone found



DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "380omojjch9pn4jpsd6avvcaq2i44imi" between the hashed NSEC3-owner "37td01nt4dbvdaeqjs3vd74kuu5aj6ne" and the hashed NextOwner "380pu3aohr72djsuhg9e1aa4dl4qlii4". So the parent zone confirmes the not-existence of a DS RR.
Bitmap: NS, DS, RRSIG Validated: RRSIG-Owner 37td01nt4dbvdaeqjs3vd74kuu5aj6ne.club., Algorithm: 8, 2 Labels, original TTL: 60 sec, Signature-expiration: 12.06.2022, 15:14:32 +, Signature-Inception: 13.05.2022, 14:33:35 +, KeyTag 15345, Signer-Name: club



DS-Query in the parent zone sends valid NSEC3 RR with the Hash "mt2hj5eb1iiu4c2c0hjcm66gsljk3jif" as Owner. That's the Hash of "club" with the NextHashedOwnerName "mt3p5dl1i0k121li4fvq5nfldn532o8p". So that domain name is the Closest Encloser of "sim4n6.club". Opt-Out: True.

1. General Results, most used to calculate the result

Aname "sim4n6.club" is domain, public suffix is ".club", top-level-domain is ".club", top-level-domain-type is "generic", tld-manager is ".CLUB DOMAINS, LLC", num .club-domains preloaded: 273 (complete: 175327)
Agood: No asked Authoritative Name Server had a timeout
HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.

AGood: Only one SOA.Primary Name Server found.: ns1.dns.nic.club.

Warning: No CAA entry with issue/issuewild found, every CAA can create a certificate. Read https://en.wikipedia.org/wiki/DNS_Certification_Authority_Authorization to learn some basics about the idea of CAA. Your name server must support such an entry. Not all dns providers support CAA entries.

3. Content- and Performance-critical Checks

AGood: 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
