	DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "2u1kkoolq4dpaflf6gs3dkam9cp8agov" between the hashed NSEC3-owner "2u1kh8u149nkj1pt9lp0u111ntibrn81" and the hashed NextOwner "2u1kmu7ctjc1cda3s0hp5o9jlh8sej50".

7. Comments

	1. General Results, most used to calculate the result
A	name "s1acker.com" is domain, public suffix is ".com", top-level-domain is ".com", top-level-domain-type is "generic", tld-manager is "VeriSign Global Registry Services", num .com-domains preloaded: 103088 (complete: 263653)
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
	HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
B	No _mta-sts TXT record found (mta-sts: Mail Transfer Agent Strict Transport Security - see RFC 8461). Read the result of server-daten.de (Url-Checks, Comments, Connections and DomainServiceRecords) to see a complete definition. Domainname: _mta-sts.s1acker.com
	2. Header-Checks
U		No https result with http status 2 or 4 (standard-check) found, no header checked.
	3. DNS- and NameServer - Checks
A	Info:: 25 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 0 Name Servers.
A	Info:: 25 Queries complete, 23 with IPv6, 2 with IPv4.
	Warning: Only some DNS Queries done via ipv6. IPv6 is the future, so the name servers of your name servers should have ipv6 addresses.
A	Info:: 4 different Name Servers found: curitiba.ns.porkbun.com, fortaleza.ns.porkbun.com, maceio.ns.porkbun.com, salvador.ns.porkbun.com, 4 Name Servers included in Delegation: curitiba.ns.porkbun.com, fortaleza.ns.porkbun.com, maceio.ns.porkbun.com, salvador.ns.porkbun.com, 4 Name Servers included in 1 Zone definitions: curitiba.ns.porkbun.com, fortaleza.ns.porkbun.com, maceio.ns.porkbun.com, salvador.ns.porkbun.com, 1 Name Servers listed in SOA.Primary: curitiba.ns.porkbun.com.
A	Good: Only one SOA.Primary Name Server found.: curitiba.ns.porkbun.com.
A	Good: SOA.Primary Name Server included in the delegation set.: curitiba.ns.porkbun.com.
A	Good: 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: curitiba.ns.porkbun.com, fortaleza.ns.porkbun.com, maceio.ns.porkbun.com, salvador.ns.porkbun.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	Good: Minimal 2 different name servers (public suffix and public ip address) found: 4 different Name Servers found
A	Good: All name servers have ipv4- and ipv6-addresses.: 4 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.: 4 Name Servers, 1 Top Level Domain: com
	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: porkbun.com
A	Good: Name servers with different Country locations found: 4 Name Servers, 2 Countries: CA, US
A	Info: Ipv4-Subnet-list: 4 Name Servers, 2 different subnets (first Byte): 162., 173., 2 different subnets (first two Bytes): 162.159., 173.245., 4 different subnets (first three Bytes): 162.159.10., 162.159.11., 162.159.8., 173.245.58.
A	Good: Name Server IPv4-addresses from different subnet found:
A	Info: IPv6-Subnet-list: 4 Name Servers with IPv6, 1 different subnets (first block): 2400:, 1 different subnets (first two blocks): 2400:cb00:, 1 different subnets (first three blocks): 2400:cb00:2049:, 1 different subnets (first four blocks): 2400:cb00:2049:0001:
	Fatal: All Name Server IPv6 addresses from the same subnet.
A	Good: Nameserver supports TCP connections: 8 good Nameserver
A	Good: Nameserver supports Echo Capitalization: 8 good Nameserver
A	Good: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 8 good Nameserver
	Nameserver doesn't pass all EDNS-Checks: curitiba.ns.porkbun.com: OP100: no result. FLAGS: no result. V1: no result. V1OP100: no result. V1FLAGS: no result. DNSSEC: no result. V1DNSSEC: no result. NSID: no result. COOKIE: no result. CLIENTSUBNET: no result.
	Nameserver doesn't pass all EDNS-Checks: fortaleza.ns.porkbun.com / 2400:cb00:2049:1::a29f:88c: OP100: ok. FLAGS: ok. V1: ok. V1OP100: fatal timeout. V1FLAGS: ok. DNSSEC: ok. V1DNSSEC: ok. NSID: ok (67m120). COOKIE: ok. CLIENTSUBNET: ok.
A	Good: 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
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: 91354 milliseconds, 91.354 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" > of the last months 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

No https result http status 200 and Content-Type text/html or text/xml found, no Html-Parsing - Check

13. Nameserver - IP-Adresses

Required Root-climbing DNS-Queries to find ip addresses of all Name Servers: curitiba.ns.porkbun.com, fortaleza.ns.porkbun.com, maceio.ns.porkbun.com, salvador.ns.porkbun.com
