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 "mc3vqcdpj0stmmp80ldno6ndk5ue06md" between the hashed NSEC3-owner "mc3veij9rvb4bhp84l0mvnbfv3v94hts" and the hashed NextOwner "mc3vtpmf13n8botbto9gn60s8gdjm4k1". 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 "a1rt98bs5qgc9nfi51s9hci47uljg6jh" as Owner. That's the Hash of "net" with the NextHashedOwnerName "a1rtlnpgulogn7b9a62shje1u3ttp8dr". So that domain name is the Closest Encloser of "vholst.net". Opt-Out: True.

7. Comments


1. General Results, most used to calculate the result

Aname "vholst.net" is domain, public suffix is ".net", top-level-domain is ".net", top-level-domain-type is "generic", tld-manager is "VeriSign Global Registry Services", num .net-domains preloaded: 6852 (complete: 168171)
AGood: All ip addresses are public addresses
Warning: Only one ip address found: vholst.net has only one ip address.
Warning: No ipv6 address found. Ipv6 is the future with a lot of new features. So every domain name should have an ipv6 address. See https://en.wikipedia.org/wiki/IPv6: vholst.net has no ipv6 address.
AGood: No asked Authoritative Name Server had a timeout
ADNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
AGood: destination is https
AGood - only one version with Http-Status 200
AGood: one preferred version: non-www is preferred
AGood: No cookie sent via http.
AGood: every https has a Strict Transport Security Header
AGood: HSTS max-age is long enough, 31536000 seconds = 365 days

Error - Certificate isn't trusted, RemoteCertificateNameMismatch
Info: Checking all ip addresses of that domain without sending the hostname only one certificate found. Checking all ip addresses and sending the hostname only one certificate found. Both certificates are the same. So that domain doesn't require Server Name Indication (SNI), it's the primary certificate of that set of ip addresses.: Domain vholst.net, 1 ip addresses, 1 different http results.

4. Content- and Performance-critical Checks

http://vholst.net/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 95.216.139.238
502

Fatal: Check of /.well-known/acme-challenge/random-filename has a http status 500 - 599, Server Error. Creating a Letsencrypt certificate via http-01 challenge can't work. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
AGood: No https + http status 200 with inline CSS / JavaScript found
AGood: Every https result with status 200 has a minified Html-Content with a quota lower then 110 %.
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

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.
