7. Comments

	1. General Results, most used to calculate the result
A	name "ivnk.dev" is domain, public suffix is "dev", top-level-domain-type is "generic", tld-manager is "Charleston Road Registry Inc."
A	Good: All ip addresses are public addresses
A	Good: No asked Authoritative Name Server had a timeout
A	Good: destination is https
A	Good - only one version with Http-Status 200
A	Good: one preferred version: non-www is preferred
A	Good: every https has a Strict Transport Security Header
A	Good: HSTS max-age is long enough, 31536000 seconds = 365 days
A	Good: HSTS has includeSubdomains - directive
A	Good: HSTS has preload directive
A	Excellent: Domain is in the Google-Preload-List
A	Excellent: Domain is in the Mozilla/Firefox-Preload-List
A	HSTS-Preload-Status: Preloaded. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
A	Good: Some urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset):0 complete Content-Type - header (3 urls)
	https://ivnk.dev/ 178.128.203.107			Url with incomplete Content-Type - header - missing charset

	https://ivnk.dev/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de			Url with incomplete Content-Type - header - missing charset
A	http://ivnk.dev/ 178.128.203.107	301	https://ivnk.dev/	Correct redirect http - https with the same domain name
A	http://ivnk.dev/ 2a03:b0c0:3:e0::396:3001	301	https://ivnk.dev/	Correct redirect http - https with the same domain name
A	http://www.ivnk.dev/ 178.128.203.107	301	https://www.ivnk.dev/	Correct redirect http - https with the same domain name
A	http://www.ivnk.dev/ 2a03:b0c0:3:e0::396:3001	301	https://www.ivnk.dev/	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
A	Good: 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: ns-cloud-c1.googledomains.com,ns-cloud-c2.googledomains.com,ns-cloud-c3.googledomains.com,ns-cloud-c4.googledomains.com
A	Good: Nameserver supports TCP connections: 8 good Nameserver
A	Good: Nameserver supports Echo Capitalization: 8 good Nameserver
A	Good: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 8 good Nameserver
A	Good: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 8 good Nameserver
A	Good: 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
A	Good: 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.
	https://ivnk.dev/ 178.128.203.107	200		Warning: https result with status 200 and size greater then 1024 Bytes without Compression found. Add Compression support (gzip, deflate, br - these are checked) so the html content is compressed.
	https://ivnk.dev/ 2a03:b0c0:3:e0::396:3001	200		Warning: https result with status 200 and size greater then 1024 Bytes without Compression found. Add Compression support (gzip, deflate, br - these are checked) so the html content is compressed.
A	Good: Every https result with status 200 has a minified Html-Content with a quota lower then 110 %.
A	Good: Every https connection via port 443 supports the http/2 protocol via ALPN.
A	Info: No img element found, no alt attribute checked
A	Good: 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

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
