DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "jgu89cl55sbadrkkn8do8fnio2c9pkqu" between the hashed NSEC3-owner "jgu756upmofo8csg0daa6ipjlug3rrrl" and the hashed NextOwner "jgua6q767657ovsfeev67rdlj9h181u4". 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 "down.net". Opt-Out: True.

7. Comments


1. General Results, most used to calculate the result

Aname "crystal.degruiter.down.net" is subdomain, 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: 9200 (complete: 240622)
AGood: No asked Authoritative Name Server had a timeout
ADNS: "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.
BNo _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.crystal.degruiter.down.net

2. Header-Checks (Cross-Origin-* headers are alpha - started 2024-06-05)

No https result with http status 2** or 4** (standard-check) found, no header checked.

3. DNS- and NameServer - Checks

AInfo:: 2 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 2 Name Servers.
AInfo:: 2 Queries complete, 2 with IPv6, 0 with IPv4.
AGood: All DNS Queries done via IPv6.
AGood: Some ip addresses of name servers found with the minimum of two DNS Queries. One to find the TLD-Zone, one to ask the TLD-Zone.ns.webair.net (67.55.123.1), ns2.webair.net (199.193.75.1)
AGood (1 - 3.0):: An average of 1.0 queries per domain name server required to find all ip addresses of all name servers.
AInfo:: 2 different Name Servers found: ns.webair.net, ns2.webair.net, 2 Name Servers included in Delegation: ns.webair.net, ns2.webair.net, 2 Name Servers included in 1 Zone definitions: ns.webair.net, ns2.webair.net, 1 Name Servers listed in SOA.Primary: ns.webair.net.
AGood: Only one SOA.Primary Name Server found.: ns.webair.net.
AGood: SOA.Primary Name Server included in the delegation set.: ns.webair.net.
AGood: All Name Server Domain Names have a Public Suffix.
AGood: All Name Server Domain Names ending with a Public Suffix have minimal one IPv4- or IPv6 address.
AGood: All Name Server ip addresses are public.
AInfo: Ipv4-Subnet-list: 2 Name Servers, 2 different subnets (first Byte): 199., 67., 2 different subnets (first two Bytes): 199.193., 67.55., 2 different subnets (first three Bytes): 199.193.75., 67.55.123.
AExcellent: Every Name Server IPv4-address starts with an unique Byte.
Nameserver doesn't pass all EDNS-Checks: ns.webair.net: OP100: no result. FLAGS: no result. V1: no result. V1OP100: no result. V1FLAGS: no result. DNSSEC: no result. V1DNSSEC: no result. NSID: no result. COOKIE: no result. CLIENTSUBNET: no result.

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

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.
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

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.

Small Code update, wait one minute
