	DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "bjqemtbhqv2ttme27l9qr2rt58apdqa2" between the hashed NSEC3-owner "bjq1lntefck31g5701umff4bft98vjcr" and the hashed NextOwner "bjqh92i9gu5as4ejtrhk1u29j9nvihet". So the parent zone confirmes the not-existence of a DS RR. Bitmap: NS, DS, RRSIG Validated: RRSIG-Owner bjq1lntefck31g5701umff4bft98vjcr.online., Algorithm: 8, 2 Labels, original TTL: 900 sec, Signature-expiration: 30.08.2024, 17:09:44 +, Signature-Inception: 31.07.2024, 15:39:44 +, KeyTag 40750, Signer-Name: online


	DS-Query in the parent zone sends valid NSEC3 RR with the Hash "1ribnbjb5koke6vekotivtq00v2eqsdj" as Owner. That's the Hash of "online" with the NextHashedOwnerName "1riid8g9tuqkkq0g8doh8lu6fddm3pu9". So that domain name is the Closest Encloser of "stoff81.online". Opt-Out: True.

	The ClosestEncloser says, that "*.online" with the Hash "87bmdi0a1gjrjop3fv5010fhb8ondd76" 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 "87bijoaphtvh72qqvoejb6janhsel6h4" and the Next Owner "87clo070ng0hopsn534i6lc5rsijfong", so the Hash of the wildcard is between these hashes. So that NSEC3 proves the Not-existence of that wildcard expansion.

	1. General Results, most used to calculate the result
A	name "stoff81.online" is domain, public suffix is ".online", top-level-domain is ".online", top-level-domain-type is "generic", tld-manager is "DotOnline Inc.", num .online-domains preloaded: 604 (complete: 245733)
A	Good: No asked Authoritative Name Server had a timeout
A	DNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
	HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
B	No _mta-sts TXT record found (mta-sts: Mail Transfer Agent Strict Transport Security - see RFC 8461). Read the result of server-daten.de (Url-Checks, Comments, Connections and DomainServiceRecords) to see a complete definition. Domainname: _mta-sts.stoff81.online
	2. Header-Checks (Cross-Origin-* headers are alpha - started 2024-06-05)
U		No https result with http status 2 or 4 (standard-check) found, no header checked.

A	Good: Only one SOA.Primary Name Server found.: ns0.centralnic.net.

A	Good: Nameserver supports TCP connections: 4 good Nameserver
A	Good: Nameserver supports Echo Capitalization: 4 good Nameserver
A	Good: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 4 good Nameserver
A	Good: All SOA have the same Serial Number
	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.
	4. Content- and Performance-critical Checks
	Info: Creating a Letsencrypt certificate with that domain name isn't possible. To create a certificate you need a registered, worldwide unique domain name. The domain name ends with a public suffix, that's good (not Grade Z). But the domain isn't registered. If you want a certificate with that domain name, you have to proof that you are the domain owner. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
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
