	DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "8j6o4o94ikdjjl6lbn347ds6lj6sgh1o" between the hashed NSEC3-owner "8j5t2b1q1ho9p5lsfdk26hmn1gu5uqip" and the hashed NextOwner "8j6p7kq55mji5vg3lv9rkd32d3f6miks". So the parent zone confirmes the not-existence of a DS RR.

	DS-Query in the parent zone sends valid NSEC3 RR with the Hash "52ko96budrr3nmfkc8cbka2vfqnm5jps" as Owner. That's the Hash of "io" with the NextHashedOwnerName "52lutsdksgkqrk7m3ijuqcal9s5c8tt3".

7. Comments

	1. General Results, most used to calculate the result
A	name "1rx.io" is domain, public suffix is ".io", top-level-domain is ".io", top-level-domain-type is "country-code", Country is British Indian Ocean Territory (the), tld-manager is "IO Top Level Domain Registry", num .io-domains preloaded: 2787 (complete: 276475)
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.1rx.io
	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:: 13 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 4 Name Servers.
A	Info:: 13 Queries complete, 13 with IPv6, 0 with IPv4.
A	Good: All DNS Queries done via IPv6.

	Nameserver doesn't pass all EDNS-Checks: a0.nic.io: OP100: ok. FLAGS: ok. V1: ok. V1OP100: ok. V1FLAGS: ok. DNSSEC: ok. V1DNSSEC: ok. NSID: SOA expected, but NOT found, NOERR expectend and NOERR found, Version 0 expectend and found (fra1.micro.hosts.meta.redstone.afilias-nst.info-1740000113). COOKIE: fatal timeout. CLIENTSUBNET: ok.
	Nameserver doesn't pass all EDNS-Checks: dns1.p05.nsone.net: 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.

A	Good: CAA entries found, creating certificate is limited: sectigo.com is allowed to create certificates
A	Good: CAA entries found, creating certificate is limited: sectigo.com is allowed to create wildcard-certificates
	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
