A	Good: All DNS Queries done via IPv6.
	Ok (4 - 8):: An average of 3.3 queries per domain name server required to find all ip addresses of all name servers.
A	Info:: 4 different Name Servers found: ns1.gandi.net, ns-151-c.gandi.net, ns-38-a.gandi.net, ns-67-b.gandi.net, 3 Name Servers included in Delegation: ns-151-c.gandi.net, ns-38-a.gandi.net, ns-67-b.gandi.net, 3 Name Servers included in 1 Zone definitions: ns-151-c.gandi.net, ns-38-a.gandi.net, ns-67-b.gandi.net, 1 Name Servers listed in SOA.Primary: ns1.gandi.net.
A	Good: Only one SOA.Primary Name Server found.: ns1.gandi.net.
	Error: SOA.Primary Name Server not included in the delegation set.: ns1.gandi.net.
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-151-c.gandi.net, ns-38-a.gandi.net, ns-67-b.gandi.net

	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: gandi.net
	Warning: All Name Servers from the same Country / IP location.: 4 Name Servers, 1 Countries: FR
A	Info: Ipv4-Subnet-list: 4 Name Servers, 3 different subnets (first Byte): 173., 213., 217., 3 different subnets (first two Bytes): 173.246., 213.167., 217.70., 3 different subnets (first three Bytes): 173.246.100., 213.167.230., 217.70.187.

	Nameserver doesn't pass all EDNS-Checks: ns1.gandi.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.
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
	http://georg-ledermann.de/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 116.203.125.190	-14		Fatal: Check of /.well-known/acme-challenge/random-filename has a timeout. Creating a Letsencrypt certificate via http-01 challenge can't work. You need a running webserver (http) and an open port 80. If it's a home server + ipv4, perhaps a correct port forwarding port 80 extern ⇒ working port intern is required. Port 80 / http can redirect to another domain port 80 or port 443, but not other ports. If it's a home server, perhaps your ISP blocks port 80. Then you may use the dns-01 challenge. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.

A	Good: Every https result with status 200 and greater 1024 Bytes is compressed (gzip, deflate, br checked).
	https://ledermann.dev/	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.
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.
	https://ledermann.dev/	200		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.: 1 script elements without defer/async.
A	Good: All CSS / JavaScript files are sent compressed (gzip, deflate, br checked). That reduces the content of the files. 2 external CSS / JavaScript files found
A	Good: 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. 2 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. 0 image files without Cache-Control-Header, 1 with Cache-Control, but no max-age, 0 with Cache-Control max-age too short (minimum 7 days), 1 with Cache-Control long enough, 2 complete.
A	Good: All checked attribute values are enclosed in quotation marks (" or ').
A	Good: All img-elements have a valid alt-attribute.: 2 img-elements found.
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
