0 DS RR in the parent zone found



DS-Query in the parent zone has a valid NSEC RR as result with the domain name between the NSEC-Owner "crnrc.se" and the NextOwner "crntt.se". So the parent zone confirmes the non-existence of a DS RR.

1. General Results, most used to calculate the result

Aname "crnrc.se" is domain, public suffix is "se", top-level-domain-type is "country-code", Country is Sweden, tld-manager is "The Internet Infrastructure Foundation"
Agood: No asked Authoritative Name Server had a timeout
ADNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
XFatal error: Nameserver doesn't support TCP connection: g.ns.se: Timeout

2. DNS- and NameServer - Checks

AInfo:: 2 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 5 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.ns1.he.net (2001:470:100::2, 216.218.130.2), ns2.he.net (2001:470:200::2, 216.218.131.2), ns3.he.net (2001:470:300::2, 216.218.132.2), ns4.he.net (2001:470:400::2, 216.66.1.2), ns5.he.net (2001:470:500::2, 216.66.80.18)
AGood (1 - 3.0):: An average of 0.4 queries per domain name server required to find all ip addresses of all name servers.
AInfo:: 5 different Name Servers found: ns1.he.net, ns2.he.net, ns3.he.net, ns4.he.net, ns5.he.net, 5 Name Servers included in Delegation: ns1.he.net, ns2.he.net, ns3.he.net, ns4.he.net, ns5.he.net, 5 Name Servers included in 1 Zone definitions: ns1.he.net, ns2.he.net, ns3.he.net, ns4.he.net, ns5.he.net, 1 Name Servers listed in SOA.Primary: ns1.he.net.
AGood: Only one SOA.Primary Name Server found.: ns1.he.net.
AGood: SOA.Primary Name Server included in the delegation set.: ns1.he.net.
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.he.net, ns2.he.net, ns3.he.net, ns4.he.net, ns5.he.net
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 servers have ipv4- and ipv6-addresses.: 5 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.: 5 Name Servers, 1 Top Level Domain: net
Warning: All Name Servers have the same domain name. If there is a problem with that domain name (or with the name servers of that domain name), your domain may be affected. Better: Use Name Servers with different domain names / different top level domains.: Only one domain name used: he.net
Warning: All Name Servers from the same Country / IP location.: 5 Name Servers, 1 Countries: US

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.

3. Content- and Performance-critical Checks

AInfo: No img element found, no alt attribute checked
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
