DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "kii0q4s9q6sa0bgakhg72s7dokeik9eo" between the hashed NSEC3-owner "kihup7oslgb87jb64328adfd6788hl4q" and the hashed NextOwner "kii1pdgqvan9sc6ias8upvt5n9p1v7pb". 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 "tjlb7qbojvmlf1s6gdriru7vsms1lg16" as Owner. That's the Hash of "de" with the NextHashedOwnerName "tjld25ej1nkgcshq3om1j58dha96ulk7". So that domain name is the Closest Encloser of "ckc-it.de". Opt-Out: True.

7. Comments


1. General Results, most used to calculate the result

Aname "ckc-it.de" is domain, public suffix is ".de", top-level-domain is ".de", top-level-domain-type is "country-code", Country is Germany, tld-manager is "DENIC eG"
AGood: All ip addresses are public addresses
AGood: Minimal 2 ip addresses per domain name found: ckc-it.de has 2 different ip addresses (authoritative).
AGood: Minimal 2 ip addresses per domain name found: www.ckc-it.de has 2 different ip addresses (authoritative).
AGood: Ipv4 and Ipv6 addresses per domain name found: ckc-it.de has 1 ipv4, 1 ipv6 addresses
AGood: Ipv4 and Ipv6 addresses per domain name found: www.ckc-it.de has 1 ipv4, 1 ipv6 addresses
AGood: No asked Authoritative Name Server had a timeout
AGood: destination is https
AGood - only one version with Http-Status 200
AGood: one preferred version: www is preferred
AGood: every https has a Strict Transport Security Header
AGood: HSTS max-age is long enough, 31536000 seconds = 365 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)

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: Every https result with status 200 and greater 1024 Bytes is compressed (gzip, deflate, br checked).

Critical: Some script Elements (type text/javascript) with a src-Attribute don't have a defer / async - Attribute. Loading and executing these JavaScripts blocks parsing and rendering the Html-Output. That's bad if your site is large or the connection is slow / mobile usage. Use "async" if the js file has only functions (so nothing is executed after parsing the file) or is independend. Use "defer" if the order of the scripts is important. All "defer" scripts are executed before the DOMContentLoaded event is fired. Check https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script to see some details.: 25 script elements without defer/async.

Warning: CSS / JavaScript found without Compression. Compress these ressources, gzip, deflate, br are checked. 6 external CSS / JavaScript files without GZip found - 108 with GZip, 114 complete
AGood: All images with internal compression not compressed. Some Images (.png, .jpg, .jpeg, .webp, .gif) are already compressed, so an additional compression isn't helpful. 16 images (type image/png, image/jpg) found without additional GZip. Not required because these images are already compressed
Warning: CSS / JavaScript files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 106 external CSS / JavaScript files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 8 with Cache-Control max-age too short (minimum 7 days), 0 with Cache-Control long enough, 114 complete.
Warning: Images with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 16 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), 0 with Cache-Control long enough, 16 complete.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
Wrong: img-elements without alt-attribute or empty alt-attribute found. The alt-attribute ("alternative") is required and should describe the img. So Screenreader and search engines are able to use these informations.: 16 img-elements without alt-attribute, 0 img-elements with empty alt-attribute found.
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
