DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "ji4hnvcrh2ja1b9ban9dfo0e6rgs4f1s" between the hashed NSEC3-owner "jhv3g0cqcgdtbbsrqa1u8njvku9tmd8t" and the hashed NextOwner "ji5q8n28qp5m88dum16muor75osnuiuq".

7. Comments


1. General Results, most used to calculate the result

Aname "ardo.it" is domain, public suffix is "it", top-level-domain-type is "country-code", Country is Italy, tld-manager is "IIT - CNR"
AGood: All ip addresses are public addresses
AGood: No asked Authoritative Name Server had a timeout
Ahttps://ardo.it/ 18.197.184.161
301
https://ardo.it/it
Correct redirect https to https

301
https://ardo.it/it/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de
Correct redirect https to https
AGood: destination is https
AGood - only one version with Http-Status 200
AGood: one preferred version: non-www is preferred
AGood: every cookie sent via https is marked as secure
AGood: every https has a Strict Transport Security Header
AGood: HSTS max-age is long enough, 63072000 seconds = 730 days
AGood: HSTS has includeSubdomains - directive
AGood: HSTS has preload directive
Warning: HSTS preload sent, but not in Preload-List. Never send a preload directive if you don't know what preload means. Check https://hstspreload.org/ to learn the basics about the Google-Preload list. If you send a preload directive, you should **immediately** add your domain to the HSTS preload list via https://hstspreload.org/ . If Google accepts the domain, so the status is "pending": Note that new entries are hardcoded into the Chrome source code and can take several months before they reach the stable version. So you will see this message some months. If you don't want that or if you don't understand "preload", but if you send a preload directive and if you have correct A-redirects, everybody can add your domain to that list. Then you may have problems, it's not easy to undo that. So if you don't want your domain preloaded, remove the preload directive.
HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
AGood: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)
Ahttp://ardo.it/ 18.197.184.161
301
https://ardo.it/
Correct redirect http - https with the same domain name
Ahttp://www.ardo.it/ 18.197.184.161
301
https://www.ardo.it/
Correct redirect http - https with the same domain name

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


3. DNS- and NameServer - Checks

AGood: Consistency between delegation and zone. The set of NS records served by the authoritative name servers must match those proposed for the delegation in the parent zone. Ordered list of name servers: regulus.fastnet.it,rigel.fastnet.it
AGood: Nameserver supports TCP connections: 4 good Nameserver
AGood: Nameserver supports Echo Capitalization: 4 good Nameserver
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 4 good Nameserver
Nameserver doesn't pass all EDNS-Checks: regulus.fastnet.it: 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

https://ardo.it/it/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de
403

Fatal: Check of /.well-known/acme-challenge/random-filename has a http status 401 / 403 Not Allowed / Forbidden. A http status 404 - Not Found - is expected. Creating a Letsencrypt certificate via http-01 challenge may not work. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
AGood: Every https result with status 200 and greater 1024 Bytes is compressed (gzip, deflate, br checked).
https://ardo.it/it
200

Warning: Https + http status 200 + Inline CSS / JavaScript found. Don't use inline CSS / JavaScript. These are compiled and re-used ressources, save these with a long Cache-Control max-age - header.
https://ardo.it/it
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 CSS / JavaScript files are sent compressed (gzip, deflate, br checked). That reduces the content of the files. 7 external CSS / JavaScript files found
AGood: All CSS / JavaScript files are sent with a long Cache-Control header (minimum 7 days). So the browser can re-use these files, no download is required. 7 external CSS / JavaScript files with long Cache-Control max-age found
Warning: Images with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 1 image files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 0 with Cache-Control max-age too short (minimum 7 days), 16 with Cache-Control long enough, 17 complete.
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.
