1. General Results, most used to calculate the result

Aname "tcd.ie" is domain, public suffix is "ie", top-level-domain-type is "country-code", Country is Ireland, tld-manager is "University College Dublin Computing Services Computer Centre"
Agood: All ip addresses are public addresses
AGood: Minimal 2 ip addresses per domain name found: tcd.ie has 2 different ip addresses (authoritative).
Warning: Only one ip address found: www.tcd.ie 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: tcd.ie has no ipv6 address.

Wrong redirect one domain http to other domain http. First redirect to https without changing the domain, so no new dns query is required. So the server can send the HSTS header. That's fundamental using HSTS (Http Strict Transport Security). First step: Add correct redirects http ⇒ https. Perhaps in your port 80 vHost something like "RewriteEngine on" + "RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,QSA,R=permanent]" (two rows, without the "). Don't add this in your port 443 vHost, that would create a loop. Then recheck your domain, should be Grade C. There is the rule to select one https version as preferred version.

2. DNS- and NameServer - Checks

AInfo:: 2 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 4 Name Servers.
AInfo:: 2 Queries complete, 2 with IPv6, 0 with IPv4.
AGood: All DNS Queries done via IPv6.
AGood: 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.auth-ns1.tcd.ie (134.226.14.26), auth-ns2.tcd.ie (134.226.14.28), auth-ns2.ucd.ie (137.43.132.54, 2001:770:98:200::35:2), auth-ns3.tcd.ie (193.1.193.161)
AGood (1 - 3.0):: An average of 0.5 queries per domain name server required to find all ip addresses of all name servers.
AInfo:: 4 different Name Servers found: auth-ns1.tcd.ie, auth-ns2.tcd.ie, auth-ns2.ucd.ie, auth-ns3.tcd.ie, 4 Name Servers included in Delegation: auth-ns1.tcd.ie, auth-ns2.tcd.ie, auth-ns2.ucd.ie, auth-ns3.tcd.ie, 4 Name Servers included in 1 Zone definitions: auth-ns1.tcd.ie, auth-ns2.tcd.ie, auth-ns2.ucd.ie, auth-ns3.tcd.ie, 1 Name Servers listed in SOA.Primary: auth-ns1.tcd.ie.
AGood: Only one SOA.Primary Name Server found.: auth-ns1.tcd.ie.
AGood: SOA.Primary Name Server included in the delegation set.: auth-ns1.tcd.ie.
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: auth-ns1.tcd.ie, auth-ns2.tcd.ie, auth-ns2.ucd.ie, auth-ns3.tcd.ie
AGood: All Name Server Domain Names have a Public Suffix.
AGood: All Name Server Domain Names ending with a Public Suffix have minimal one IPv4- or IPv6 address.
AGood: All Name Server ip addresses are public.
AGood: Minimal 2 different name servers (public suffix and public ip address) found: 4 different Name Servers found
AGood: Some Name Servers have IPv6 addresses: 1 Name Servers with IPv6 found (3 Name Servers without IPv6)
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.: 4 Name Servers, 1 Top Level Domain: ie

3. Content- and Performance-critical Checks

https://www.tcd.ie/ 134.226.14.234
200

Warning: https result with status 200 and size greater then 1024 Bytes without GZip found. Add GZip support so the html content is compressed.
https://www.tcd.ie/ 134.226.14.234
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://www.tcd.ie/ 134.226.14.234
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.
https://www.tcd.ie/ 134.226.14.234
200

Warning: Https connections (Standard Port 443) found without support of the http/2 protocol via ALPN. 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.
https://www.tcd.ie/ 134.226.14.234
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.: 9 script elements without defer/async.
Warning: CSS / JavaScript found without GZip support. Send these ressources with GZip. 17 external CSS / JavaScript files without GZip found - 4 with GZip, 21 complete
AGood: All images with internal compression not sent via GZip. Images (.png, .jpg) are already compressed, so an additional GZip isn't helpful. 3 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. 13 external CSS / JavaScript files without Cache-Control-Header, 4 with Cache-Control, but no max-age, 2 with Cache-Control max-age too short (minimum 7 days), 2 with Cache-Control long enough, 21 complete.
Warning: Images with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 15 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, 15 complete.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AGood: Some img-elements have a valid alt-attribute.: 15 img-elements found, 5 img-elements with correct alt-attributes (defined, not an empty value).
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.: 10 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
