0 DS RR in the parent zone found






DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "884vdo6q6htduvcjs9jt1um825h31ljf" between the hashed NSEC3-owner "884vdo6q6htduvcjs9jt1um825h31ljf" and the hashed NextOwner "89hjkglra9sjsecm0itqmmj9m2lrp31r". So the parent zone confirmes the not-existence of a DS RR.

7. Comments


1. General Results, most used to calculate the result

Aname "giss.nasa.gov" is subdomain, public suffix is "gov", top-level-domain-type is "sponsored", tld-manager is "General Services Administration Attn: QTDC, 2E08 (.gov Domain Registration)"
AGood: All ip addresses are public addresses
AGood: No asked Authoritative Name Server had a timeout
AGood: destination is https
AGood - only one version with Http-Status 200
AGood: one preferred version: www is preferred
AGood: every https has a Strict Transport Security Header
AGood: HSTS max-age is long enough, 31536000 seconds = 365 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.
AGood: Some urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset):1 complete Content-Type - header (3 urls)
https://www.giss.nasa.gov/ 129.164.128.233


Url with incomplete Content-Type - header - missing charset
https://www.giss.nasa.gov/ 2001:4d0:2310:230::233


Url with incomplete Content-Type - header - missing charset
Ahttp://www.giss.nasa.gov/ 129.164.128.233
301
https://www.giss.nasa.gov/
Correct redirect http - https with the same domain name
Ahttp://www.giss.nasa.gov/ 2001:4d0:2310:230::233
301
https://www.giss.nasa.gov/
Correct redirect http - https with the same domain name

2. Header-Checks (Cross-Origin-* headers are alpha - started 2024-06-05)


3. DNS- and NameServer - Checks

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: ns1.nasa.gov,ns2.nasa.gov,ns3.nasa.gov
AGood: Nameserver supports TCP connections: 9 good Nameserver
AGood: Nameserver supports Echo Capitalization: 9 good Nameserver
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 9 good Nameserver
AGood: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 9 good Nameserver
AGood: 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

https://www.giss.nasa.gov/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de
403

Fatal: Check of /.well-known/acme-challenge/random-filename has a http status 401 / 403 Not Allowed / Forbidden. A http status 404 - Not Found - is expected. Creating a Letsencrypt certificate via http-01 challenge may not work. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
https://www.giss.nasa.gov/ 129.164.128.233
200

Warning: https result with status 200 and size greater then 1024 Bytes without Compression found. Add Compression support (gzip, deflate, br - these are checked) so the html content is compressed.
https://www.giss.nasa.gov/ 2001:4d0:2310:230::233
200

Warning: https result with status 200 and size greater then 1024 Bytes without Compression found. Add Compression support (gzip, deflate, br - these are checked) so the html content is compressed.
AGood: No https + http status 200 with inline CSS / JavaScript found
AGood: Every https result with status 200 has a minified Html-Content with a quota lower then 110 %.
https://www.giss.nasa.gov/ 129.164.128.233
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.

Domain Sharding and Inline-CSS/Javascript shouldn't used with http/2.
Warning: CSS / JavaScript found without Compression. Compress these ressources, gzip, deflate, br are checked. 4 external CSS / JavaScript files without GZip found - 4 with GZip, 8 complete
AGood: All images with internal compression not compressed. Some Images (.png, .jpg, .jpeg, .webp, .gif) are already compressed, so an additional compression isn't helpful. 26 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. 2 external CSS / JavaScript files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 2 with Cache-Control max-age too short (minimum 7 days), 4 with Cache-Control long enough, 8 complete.
AGood: All images are sent with a long Cache-Control header (minimum 7 days). So the browser can reuse these files, no download is required. 38 image files with long Cache-Control max-age found
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AGood: All img-elements have a valid alt-attribute.: 38 img-elements 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

  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.
