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 "6fabb6hcuj19tgg44lr37hr00rdj3gvl" between the hashed NSEC3-owner "6faatej6fp6286co1nsqe7oal2qlhff1" and the hashed NextOwner "6fadc05olapngl3af6sih8a1kujj0kae". So the parent zone confirmes the not-existence of a DS RR.

DS-Query in the parent zone sends valid NSEC3 RR with the Hash "gdtpongmpok61u9lvnipqor8lra9l4t0" as Owner. That's the Hash of "org" with the NextHashedOwnerName "gdtrea8kmj2rneqen4m2ogj26kfsukj7". So that domain name is the Closest Encloser of "duckdns.org". Opt-Out: True.

AGood: 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

ADuration: 415516 milliseconds, 415.516 seconds

 

8. Connections

No connection informations found. Perhaps only http - connections.

 

9. Certificates

No certificate informations found. Perhaps only http - connections.

 

10. Last Certificates - Certificate Transparency Log Check

1. Source CertSpotter - active certificates (one check per day)

No CertSpotter - CT-Log entries found

 

2. Source crt.sh - old and new certificates, sometimes very slow - only certificates with "not after" > of the last months are listed

No CRT - CT-Log entries found

 

11. Html-Content - Entries

No Html-Content entries found. Only checked if https + status 200/401/403/404

 

12. Html-Parsing via https://validator.nu/ / https://validator.w3.org/nu/ (started 2024-09-28, 09:00, alpha)

  Unfortunately, there are differences between the first used validator.nu and validator.w3.org/nu/ - switched to validator.w3.org/nu/. Looks like some error messages (link - fetchpriority attribute) of validator.nu are obsolete, not seen in the w3.org-version and not found in the current specification: link may have a fetchpriority attribute.

No https result http status 200 and Content-Type text/html or text/xml found, no Html-Parsing - Check
