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 "ga" and the NextOwner "gal". So the parent zone confirmes the non-existence of a DS RR.

1. General Results, most used to calculate the result

Aname "busel.ga" is domain, public suffix is ".ga", top-level-domain is ".ga", top-level-domain-type is "country-code", Country is Gabon, tld-manager is "Agence Nationale des Infrastructures Numériques et des Fréquences (ANINF)", num .ga-domains preloaded: 2441 (complete: 151507)
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.

2. DNS- and NameServer - Checks

AInfo:: 26 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 3 Name Servers.
AInfo:: 26 Queries complete, 26 with IPv6, 0 with IPv4.
AGood: All DNS Queries done via IPv6.
Bad (greater 8):: An average of 8.7 queries per domain name server required to find all ip addresses of all name servers.
AInfo:: 3 different Name Servers found: firstvds.ru, ns1.firstvds.ru, ns2.firstvds.ru, 2 Name Servers included in Delegation: ns1.firstvds.ru, ns2.firstvds.ru, 2 Name Servers included in 2 Zone definitions: ns1.firstvds.ru, ns2.firstvds.ru, 1 Name Servers listed in SOA.Primary: firstvds.ru.
AGood: Only one SOA.Primary Name Server found.: firstvds.ru.
Error: SOA.Primary Name Server not included in the delegation set.: firstvds.ru.
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 Server ip addresses are public.
AGood: Minimal 2 different name servers (public suffix and public ip address) found: 3 different Name Servers found
AGood: Some Name Servers have IPv6 addresses: 2 Name Servers with IPv6 found (1 Name Servers without IPv6)
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: ru
AGood: Name Servers with different domain names found.: 2 different Domains found
Warning: All Name Servers from the same Country / IP location.: 3 Name Servers, 1 Countries: RU
AInfo: Ipv4-Subnet-list: 3 Name Servers, 2 different subnets (first Byte): 82., 94., 3 different subnets (first two Bytes): 82.146., 82.202., 94.250., 3 different subnets (first three Bytes): 82.146.43., 82.202.175., 94.250.248.
AGood: Name Server IPv4-addresses from different subnet found:
AInfo: IPv6-Subnet-list: 2 Name Servers with IPv6, 1 different subnets (first block): 2a01:, 1 different subnets (first two blocks): 2a01:0230:, 1 different subnets (first three blocks): 2a01:0230:0002:, 2 different subnets (first four blocks): 2a01:0230:0002:0074:, 2a01:0230:0002:0075:

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

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
ADuration: 50553 milliseconds, 50.553 seconds


8. Connections

No connection informations found. Perhaps only http - connections.


9. Certificates

No certificate informations found. Perhaps only http - connections.


10. Last Certificates - Certificate Transparency Log Check

1. Source CertSpotter - active certificates (one check per day)

No CertSpotter - CT-Log entries found


2. Source crt.sh - old and new certificates, sometimes very slow - only certificates with "not after" > 2019 are listed

No CRT - CT-Log entries found


11. Html-Content - Entries

No Html-Content entries found. Only checked if https + status 200/401/403/404


12. Nameserver - IP-Adresses

Required Root-climbing DNS-Queries to find ip addresses of all Name Servers: firstvds.ru, ns1.firstvds.ru, ns2.firstvds.ru
