7. Comments

	1. General Results, most used to calculate the result
A	name "e.gemius.com" is subdomain, public suffix is ".com", top-level-domain is ".com", top-level-domain-type is "generic", tld-manager is "VeriSign Global Registry Services", num .com-domains preloaded: 61113 (complete: 168171)
A	Good: All ip addresses are public addresses
	Warning: Only one ip address found: e.gemius.com 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: e.gemius.com has no ipv6 address.
A	Good: No asked Authoritative Name Server had a timeout
A	DNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
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: No cookie sent via http.
A	Good: every https has a Strict Transport Security Header
A	Good: HSTS max-age is long enough, 63072000 seconds = 730 days
	HSTS-Preload-Status: unknown. Domain never included in the Preload-list. 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 (2 urls)
	https://e.gemius.com/ 91.221.127.108			Url with incomplete Content-Type - header - missing charset
	https://e.gemius.com/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de			Url with incomplete Content-Type - header - missing charset
A	http://e.gemius.com/ 91.221.127.108	301	https://e.gemius.com/	Correct redirect http - https with the same domain name
N	https://91.221.127.108/ 91.221.127.108	204		Error - Certificate isn't trusted, RemoteCertificateNameMismatch, RemoteCertificateChainErrors
	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 different. So that domain requires Server Name Indication (SNI), so the server is able to select the correct certificate.: Domain e.gemius.com, 1 ip addresses.
	2. Header-Checks (Cross-Origin-* headers are alpha - started 2024-06-05)
	3. DNS- and NameServer - Checks
A	Info:: 2 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 3 Name Servers.
A	Info:: 2 Queries complete, 2 with IPv6, 0 with IPv4.
A	Good: All DNS Queries done via IPv6.
A	Good: 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.ns1.gemius.pl (91.221.127.226), ns2.gemius.pl (146.59.66.82), ns3.gemius.pl (81.0.212.193)
A	Good (1 - 3.0):: An average of 0.7 queries per domain name server required to find all ip addresses of all name servers.
A	Info:: 3 different Name Servers found: ns1.gemius.pl, ns2.gemius.pl, ns3.gemius.pl, 3 Name Servers included in Delegation: ns1.gemius.pl, ns2.gemius.pl, ns3.gemius.pl, 3 Name Servers included in 1 Zone definitions: ns1.gemius.pl, ns2.gemius.pl, ns3.gemius.pl, 1 Name Servers listed in SOA.Primary: ns1.gemius.pl.
A	Good: Only one SOA.Primary Name Server found.: ns1.gemius.pl.
A	Good: SOA.Primary Name Server included in the delegation set.: ns1.gemius.pl.
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: ns1.gemius.pl, ns2.gemius.pl, ns3.gemius.pl
A	Good: All Name Server Domain Names have a Public Suffix.
A	Good: All Name Server Domain Names ending with a Public Suffix have minimal one IPv4- or IPv6 address.
A	Good: All Name Server ip addresses are public.
A	Good: Minimal 2 different name servers (public suffix and public ip address) found: 3 different Name Servers found
	Warning: No Name Server IPv6 address found. IPv6 is the future, so your name servers should be visible via IPv6.: 3 different Name Servers found
	Warning: All Name Servers have the same Top Level Domain / Public Suffix. If there is a problem with that Top Level Domain, your domain may be affected. Better: Use Name Servers with different top level domains.: 3 Name Servers, 1 Top Level Domain: pl
	Warning: All Name Servers have the same domain name. If there is a problem with that domain name (or with the name servers of that domain name), your domain may be affected. Better: Use Name Servers with different domain names / different top level domains.: Only one domain name used: gemius.pl
A	Good: Name servers with different Country locations found: 3 Name Servers, 2 Countries: CZ, PL
A	Info: Ipv4-Subnet-list: 3 Name Servers, 3 different subnets (first Byte): 146., 81., 91., 3 different subnets (first two Bytes): 146.59., 81.0., 91.221., 3 different subnets (first three Bytes): 146.59.66., 81.0.212., 91.221.127.
A	Excellent: Every Name Server IPv4-address starts with an unique Byte.
A	Good: Nameserver supports TCP connections: 1 good Nameserver
A	Good: Nameserver supports Echo Capitalization: 1 good Nameserver
A	Good: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 1 good Nameserver

	4. Content- and Performance-critical Checks
	https://e.gemius.com/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de	200		Warning: Not existing ACME-file, but Server sends 200, not 404 or redirect. May be a problem creating a Letsencrypt certificate. Checking /.well-known/acme-challenge/random-filename - a http status 404 - Not Found - is expected. If your server sends content and a http status 200, the validation file (87 bytes, token, dot and the hash of the public part of the account key) may be invisible, so Letsencrypt can't validate your domain. If it is an application that sends this content, perhaps create an exception, so /.well-known/acme-challenge sends raw files. Or create a redirect to another domain and / or port 443, but your Letsencrypt client must support such a solution. Certbot: Use webroot as authenticator - https://certbot.eff.org/docs/using.html Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.

Http/2 is the new Http-Version (old: http 1.1) with some important new features. Update your server software so http/2 is available. Only one TCP-connection per Server (that's a performance boost), Header-Compression and Server Pushs are available. Domain Sharding and Inline-CSS/Javascript shouldn't used with http/2.

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.: 3 script elements without defer/async.

A	Good: All checked attribute values are enclosed in quotation marks (" or ').
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

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
