| 1. General Results, most used to calculate the result |
| A | name "comfy.dns.navy" is subdomain, public suffix is ".navy", top-level-domain is ".navy", top-level-domain-type is "generic", tld-manager is "United TLD Holdco Ltd.", num .navy-domains preloaded: 3 (complete: 276475)
|
| A | Good: All ip addresses are public addresses
|
| Warning: Only one ip address found: comfy.dns.navy 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: comfy.dns.navy has no ipv6 address.
|
| 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: No cookie sent via http.
|
| A | Good: 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.
|
| A | Good: Some urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset):0 complete Content-Type - header (1 urls)
|
| https://comfy.dns.navy/ 89.245.86.41
|
| Url with incomplete Content-Type - header - missing charset
|
| A | http://comfy.dns.navy/ 89.245.86.41

|
| Info: Checking the ip addresses of that domain name not exact one certificate found. So it's impossible to check if that domain requires Server Name Indication (SNI).: Domain comfy.dns.navy, 1 ip addresses.
|
| B | No _mta-sts TXT record found (mta-sts: Mail Transfer Agent Strict Transport Security - see RFC 8461). Read the result of server-daten.de (Url-Checks, Comments, Connections and DomainServiceRecords) to see a complete definition. Domainname: _mta-sts.comfy.dns.navy

| 2. Header-Checks |
| A | comfy.dns.navy 89.245.86.41
| Content-Security-Policy
| Ok: Header without syntax errors found: default-src 'none'; img-src 'self'; script-src 'self' 'unsafe-hashes' 'sha256-iSUhpQ6id+klZXoL31XdTGktc40c/m0sxNgxE32N7Wk='; font-src 'self'; style-src 'self'; frame-ancestors 'none'; base-uri 'none'; form-action 'self'
|
| A |
|
| Good: default-src directive only with 'none' or 'self', additional sources are blocked.
|
| A |
|
| Good: default-src without 'unsafe-inline' or 'unsave-eval'.
|
| A |
|
| Good: form-action directive found. That reduces the risk sending data to unwanted domains. form-action is a navigation-directive, so default-src isn't used.
|
| A |
|
| Good: frame-ancestors directive found. That limits pages who are allowed to use this page in a frame / iframe / object / embed / applet. frame-ancestors is a navigation-directive, so default-src isn't used.
|
| A |
|
| Good: base-uri directive found. That limits the URLs which can be used in a document's <base> element. Because it's a document directive, default-src isn't used, so an own directive is required.
|
| A |
|
| Good: No object-src found, but the default-src used as fallback is defined and restricted.
|
| A |
|
| Good: script-src without 'unsafe-inline' and 'unsafe-eval' found. That's the recommended configuration.
|
| A |
|
| Good: script-src without * and a scheme found.
|
| A |
|
| Good: script-src without data: schema found. Why is this important? The data: schema allows hidden code injection. Insert <script src='data:application/javascript;base64,YWxlcnQoJ1hTUycpOw=='></script> in your page and see what happens.
|
| A |
|
| Good: frame-src without data: defined or frame-src missing and the default-src used as fallback not allows the data: schema. That blocks hidden code injection. Insert <iframe src="data:text/html;charset=utf-8;base64,PCFET0NUWVBFIGh0bWw+PGh0bWw+PGJvZHk+PHA+YmVmb3JlPHNjcmlwdCB0eXBlPSJ0ZXh0L2phdmFzY3JpcHQiPmFsZXJ0KCdYU1MnKTwvc2NyaXB0PjxwPmFmdGVyPC9ib2R5PjwvaHRtbD4="></iframe> in your page and see what happens.

|
| Ok (4 - 8):: An average of 4.0 queries per domain name server required to find all ip addresses of all name servers.
|
| A | Info:: 4 different Name Servers found: ns1.dynv6.com, ns1.dynv6.net, ns2.dynv6.com, ns3.dynv6.com, 3 Name Servers included in Delegation: ns1.dynv6.com, ns2.dynv6.com, ns3.dynv6.com, 3 Name Servers included in 2 Zone definitions: ns1.dynv6.com, ns2.dynv6.com, ns3.dynv6.com, 1 Name Servers listed in SOA.Primary: ns1.dynv6.net.
|
| A | Good: Only one SOA.Primary Name Server found.: ns1.dynv6.net.
|
| Error: SOA.Primary Name Server not included in the delegation set.: ns1.dynv6.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: ns1.dynv6.com, ns2.dynv6.com, ns3.dynv6.com
|
| A | Good: All Name Server Domain Names have a Public Suffix.
|
| Error: Name Server Domain Names with Public Suffix and without ip address found.: 1 Name Servers without ipv4 and ipv6: 1
|
|
|
| A | Good: Minimal 2 different name servers (public suffix and public ip address) found: 3 different Name Servers found
|
| A | Good: All name servers have ipv4- and ipv6-addresses.: 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: com
|
| A | Good: Name Servers with different domain names found.: 2 different Domains found
|
| A | Good: Name servers with different Country locations found: 3 Name Servers, 2 Countries: DE, FI

| 4. Content- and Performance-critical Checks |
| http://comfy.dns.navy/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 89.245.86.41
|
| 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: No https + http status 200 with inline CSS / JavaScript found
|
| https://comfy.dns.navy/ 89.245.86.41
|
| 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://comfy.dns.navy/ 89.245.86.41
|
| 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.
|
| A | Good: All CSS / JavaScript files are sent compressed (gzip, deflate, br checked). That reduces the content of the files. 1 external CSS / JavaScript files found
|
| Warning: CSS / JavaScript files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 1 external CSS / JavaScript 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, 1 complete.
|
| Warning: Images with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 1 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, 1 complete.
|
| A | Good: All checked attribute values are enclosed in quotation marks (" or ').
|
| A | Good: All img-elements have a valid alt-attribute.: 1 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
