Attn: QTDC, 2E08 (.gov Domain Registration)", num .gov-domains preloaded: 3513 (complete: 216710) A Good: All ip addresses are public addresses Warning: Only one ip address found: expressway-e.kissimmee.gov 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: expressway-e.kissimmee.gov has no ipv6 address. A Good: No asked Authoritative Name Server had a timeout A DNS: "Name Error" means: No www-dns-entry defined.

Header-Checks (alpha, started 2022-10-23, may be buggy / incomplete) A expressway-e.kissimmee.gov Content-Security-Policy Ok: Header without syntax errors found: default-src 'self';base-uri 'self';block-all-mixed-content;child-src 'self';connect-src 'self';font-src 'self';frame-ancestors 'self';frame-src 'self';img-src 'self';manifest-src 'self';media-src 'none';object-src 'self';script-src 'self' 'unsafe-inline' 'unsafe-eval';style-src 'self' 'unsafe-inline' 'unsafe-eval';worker-src 'self'; B Info: Header-Element is deprecated. block-all-mixed-content A Good: default-src directive only with 'none' or 'self', additional sources are blocked. child-src, connect-src, font-src, frame-src, img-src, manifest-src, object-src, worker-src A Good: default-src without 'unsafe-inline' or 'unsave-eval'. child-src, connect-src, font-src, frame-src, img-src, manifest-src, object-src, worker-src E Bad: No form-action directive found. Use one to limit the form - action - destinations. 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: object-src only with 'none' or 'self' found, no scheme, no other urls. That blocks object / embed / applet - elements. F Critical: script-src with 'unsafe-inline' or 'unsafe-eval' and without a nonce found. That's dangerous, don't use it. If you really need one of these unsafe directives, add a nonce. 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. C Info: default-src and some other fetch directives have the same list of values. Remove the other fetch directive, default-src is used as fallback. Directives to remove: child-src, connect-src, font-src, frame-src, img-src, manifest-src, object-src, worker-src A X-Content-Type-Options Ok: Header without syntax errors found: nosniff A X-Frame-Options Ok: Header without syntax errors found: sameorigin B Info: Header is deprecated. May not longer work in modern browsers. sameorigin. Better solution: Use a Content-Security-Policy Header with a frame-ancestors directive. DENY - use 'none', SAMEORIGIN - use 'self'. If you want to allow some domains to frame your page, add these urls. A X-Xss-Protection Ok: Header without syntax errors found: 1; mode=block B Info: Header is deprecated. May not longer work in modern browsers. 1; mode=block F expressway-e.kissimmee.gov Referrer-Policy Critical: Missing Header: F expressway-e.kissimmee.gov Permissions-Policy Critical: Missing Header: 3. DNS- and NameServer - Checks A Info:: 2 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 2 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.dotster.com (66.96.142.146), ns2.dotster.com (65.254.254.170) A Good (1 - 3.0):: An average of 1.0 queries per domain name server required to find all ip addresses of all name servers. A Info:: 2 different Name Servers found: ns1.dotster.com, ns2.dotster.com, 2 Name Servers included in Delegation: ns1.dotster.com, ns2.dotster.com, 2 Name Servers included in 1 Zone definitions: ns1.dotster.com, ns2.dotster.com, 1 Name Servers listed in SOA.Primary: ns1.dotster.com. A Good: Only one SOA.Primary Name Server found.: ns1.dotster.com. A Good: SOA.Primary Name Server included in the delegation set.: ns1.dotster.com. 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 Info: Ipv4-Subnet-list: 2 Name Servers, 2 different subnets (first Byte): 65., 66., 2 different subnets (first two Bytes): 65.254., 66.96., 2 different subnets (first three Bytes): 65.254.254., 66.96.142.

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 https://expressway-e.kissimmee.gov/login 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://expressway-e.kissimmee.gov/login 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://expressway-e.kissimmee.gov/login 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://expressway-e.kissimmee.gov/login 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. Warning: CSS / JavaScript found without GZip support. Send these ressources with GZip. 1 external CSS / JavaScript files without GZip found - 0 with GZip, 1 complete 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. 1 external CSS / JavaScript files with long Cache-Control max-age found A Good: All images are sent with a long Cache-Control header (minimum 7 days). So the browser can reuse these files, no download is required. 2 image files with long Cache-Control max-age found A Good: All checked attribute values are enclosed in quotation marks (" or '). 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.: 2 img-elements without alt-attribute, 0 img-elements with empty alt-attribute 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 A Duration: 408874 milliseconds, 408.874 seconds
