CNAME-Query sends a valid NSEC3 RR as result with the hashed query name "b08luj3pbrhf4fi12huviuooi4cksalc" equal the hashed NSEC3-owner "b08luj3pbrhf4fi12huviuooi4cksalc" and the hashed NextOwner "fda41n157hnave62sqdk11tcad0m6k0j". So the zone confirmes the not-existence of that CNAME RR, but the existence of that query name (minimal one RR with that name exists).

AAAA-Query sends a valid NSEC3 RR as result with the hashed query name "b08luj3pbrhf4fi12huviuooi4cksalc" equal the hashed NSEC3-owner "b08luj3pbrhf4fi12huviuooi4cksalc" and the hashed NextOwner "fda41n157hnave62sqdk11tcad0m6k0j". So the zone confirmes the not-existence of that AAAA RR, but the existence of that query name (minimal one RR with that name exists).

TLSA-Query (_443._tcp.dunsel.dedyn.io) sends a valid NSEC3 RR as result with the hashed owner name "b08luj3pbrhf4fi12huviuooi4cksalc" (unhashed: dunsel.dedyn.io). So that's the Closest Encloser of the query name. TLSA-Query sends a valid NSEC3 RR as result and covers the hashed Wildcard expansion of the ClosestEncloser "dum6l4nk62uco7fi136hrefgn7vcvdtr" (unhashed: *.dunsel.dedyn.io) with the owner "b08luj3pbrhf4fi12huviuooi4cksalc" and the NextOwner "fda41n157hnave62sqdk11tcad0m6k0j". So that NSEC3 confirms the not-existence of the Wildcard expansion.

Status: Good. NXDomain-Proof required and found.






TLSA-Query sends a valid NSEC3 RR as result and covers the hashed Next Closer Name "1fai3aha8934utv9loaatnj1o0nfvbec" (unhashed: _tcp.dunsel.dedyn.io) with the owner "n6t4s5o5jokthdm52hpoksenkjsimaa7" and the NextOwner "b08luj3pbrhf4fi12huviuooi4cksalc". So that NSEC3 confirms the not-existence of the Next Closer Name. TLSA-Query (_443._tcp.dunsel.dedyn.io) sends a valid NSEC3 RR as result with the owner name "n6t4s5o5jokthdm52hpoksenkjsimaa7" greater the NextOwner-Name "b08luj3pbrhf4fi12huviuooi4cksalc", so the NSEC3 covers the end of the zone. The hashed query name "3ctvavk6hlrndo3vfreokthg6g3sroo9" comes before the hashed NextOwner, so the zone confirmes the not-existence of that TLSA RR.

0 DS RR in the parent zone found






DS-Query in the parent zone sends valid NSEC3 RR with the Hash "b08luj3pbrhf4fi12huviuooi4cksalc" as Owner. That's the Hash of "dunsel.dedyn.io" with the NextHashedOwnerName "fda41n157hnave62sqdk11tcad0m6k0j". So that domain name is the Closest Encloser of "www.dunsel.dedyn.io". Opt-Out: False.
Bitmap: A, NS, SOA, PTR, TXT, RRSIG, DNSKEY, NSEC3PARAM, CDS, CDNSKEY, CAA Validated: RRSIG-Owner b08luj3pbrhf4fi12huviuooi4cksalc.dunsel.dedyn.io., Algorithm: 13, 4 Labels, original TTL: 300 sec, Signature-expiration: 19.03.2026, 00:00:00 +, Signature-Inception: 26.02.2026, 00:00:00 +, KeyTag 11125, Signer-Name: dunsel.dedyn.io






The ClosestEncloser says, that "*.dunsel.dedyn.io" with the Hash "dum6l4nk62uco7fi136hrefgn7vcvdtr" 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 "b08luj3pbrhf4fi12huviuooi4cksalc" and the Next Owner "fda41n157hnave62sqdk11tcad0m6k0j", so the Hash of the wildcard is between these hashes. So that NSEC3 proves the Not-existence of that wildcard expansion. Opt-Out: False.

A

Good: default-src directive only with 'none' or 'self', additional sources are blocked.
A

Good: default-src without 'unsafe-inline' or 'unsave-eval'.
A

Good: form-action directive found. That reduces the risk sending data to unwanted domains. form-action is a navigation-directive, so default-src isn't used.
A

Good: frame-ancestors directive found. That limits pages who are allowed to use this page in a frame / iframe / object / embed / applet. frame-ancestors is a navigation-directive, so default-src isn't used.
A

Good: base-uri directive found. That limits the URLs which can be used in a document's <base> element. Because it's a document directive, default-src isn't used, so an own directive is required.
A

Good: No object-src found, but the default-src used as fallback is defined and restricted.
A

Good: No script-src found, but the default-src used as fallback is defined and restricted.
A

Good: frame-src without data: defined or frame-src missing and the default-src used as fallback not allows the data: schema. That blocks hidden code injection. Insert <iframe src="data:text/html;charset=utf-8;base64,PCFET0NUWVBFIGh0bWw+PGh0bWw+PGJvZHk+PHA+YmVmb3JlPHNjcmlwdCB0eXBlPSJ0ZXh0L2phdmFzY3JpcHQiPmFsZXJ0KCdYU1MnKTwvc2NyaXB0PjxwPmFmdGVyPC9ib2R5PjwvaHRtbD4="></iframe> in your page and see what happens.

4. Content- and Performance-critical Checks

AGood: All checks /.well-known/acme-challenge/random-filename without redirects answer with the expected http status 404 - Not Found. Creating a Letsencrypt certificate via http-01 challenge should work. If it doesn't work: Check your vHost configuration (apachectl -S, httpd -S, nginx -T). Every combination of port and ServerName / ServerAlias (Apache) or Server (Nginx) must be unique. Merge duplicated entries in one vHost. If you use an IIS, extensionless files must be allowed in the /.well-known/acme-challenge subdirectory. Create a web.config in that directory. Content: <configuration><system.webServer><staticContent><mimeMap fileExtension="." mimeType="text/plain" /></staticContent></system.webServer></configuration>. If you have a redirect http ⇒ https, that's ok, Letsencrypt follows such redirects to port 80 / 443 (same or other server). There must be a certificate. But the certificate may be expired, self signed or with a not matching domain name. Checking the validation file Letsencrypt ignores such certificate errors. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
AGood: No https + http status 200 with inline CSS / JavaScript found
https://dunsel.dedyn.io/ 73.164.216.153
200

Warning: Https result with status 200 found, Html-Content is too big. Should be max. 110 %. May contain inline CSS / JavaScript, too much comments or white space. Re-used ressources - create files with a long Cache-Control max-age header. Remove comments and white space.
AGood: Every https connection via port 443 supports the http/2 protocol via ALPN.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AInfo: No img element found, no alt attribute checked
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
