| 1. General Results, most used to calculate the result |
| A | name "nixnet.social" is domain, public suffix is ".social", top-level-domain is ".social", top-level-domain-type is "generic", tld-manager is "United TLD Holdco Ltd.", num .social-domains preloaded: 139 (complete: 276475)
|
| A | Good: All ip addresses are public addresses
|
| A | Good: Minimal 2 ip addresses per domain name found: nixnet.social has 2 different ip addresses (authoritative).
|
| A | Good: Ipv4 and Ipv6 addresses per domain name found: nixnet.social has 1 ipv4, 1 ipv6 addresses
|
| A | Good: No asked Authoritative Name Server had a timeout
|
| A | DNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
|
| 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
|
| 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: 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
