CNAME-Query sends a valid NSEC3 RR as result with the hashed query name "amg4agcnii59ancf11ep1eeku1rejdlt" equal the hashed NSEC3-owner "amg4agcnii59ancf11ep1eeku1rejdlt" and the hashed NextOwner "besego1ml71bj6u8it2tjup90gvmi0tf". So the zone confirmes the not-existence of that CNAME RR, but the existence of that query name (minimal one RR with that name exists).

Status: Good. NoData-Proof required and found.






TLSA-Query (_443._tcp.tiekoetter.com) sends a valid NSEC3 RR as result with the hashed owner name "amg4agcnii59ancf11ep1eeku1rejdlt" (unhashed: tiekoetter.com). So that's the Closest Encloser of the query name.

Status: Good. NoData-Proof required and found.






TLSA-Query sends a valid NSEC3 RR as result and covers the hashed Next Closer Name "qg8mrnc7cmm5u5tsh1j8h46vrq0ivi9t" (unhashed: _tcp.tiekoetter.com) with the owner "qaclj8i9rgbevvf41a6kqeqh812khvin" and the NextOwner "r7l80jvmfdk1l8hri42hmecp60pabhfv". So that NSEC3 confirms the not-existence of the Next Closer Name.

TLSA-Query sends a valid NSEC3 RR as result with the hashed owner name "k22u8fmg5h90sg25v4k8qdumjf2ngsbd" (unhashed: *.tiekoetter.com) as the Wildcard-Expansion of the Closest Encloser of the query name "9tsqr1nt51145ddifqeplkd1ecrdg638". So the Wildcard-Expansion of the Closest Encloser confirms that the query name is generated via wildcard expansion (NoError instead of NXDomain).

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.tiekoetter.net (2a03:4000:46:8ca::1, 45.83.107.43), ns2.tiekoetter.net (185.194.141.200, 2a03:4000:1c:d2c::2), ns3.tiekoetter.net (2a01:4f9:c012:68fb::1, 95.217.221.144), ns4.tiekoetter.net (2a03:b0c0:2:f0::35c:3001, 64.225.78.55)
AGood (1 - 3.0):: An average of 0.5 queries per domain name server required to find all ip addresses of all name servers.
AInfo:: 4 different Name Servers found: ns1.tiekoetter.net, ns2.tiekoetter.net, ns3.tiekoetter.net, ns4.tiekoetter.net, 4 Name Servers included in Delegation: ns1.tiekoetter.net, ns2.tiekoetter.net, ns3.tiekoetter.net, ns4.tiekoetter.net, 4 Name Servers included in 1 Zone definitions: ns1.tiekoetter.net, ns2.tiekoetter.net, ns3.tiekoetter.net, ns4.tiekoetter.net, 1 Name Servers listed in SOA.Primary: ns1.tiekoetter.net.

AInfo: Ipv4-Subnet-list: 4 Name Servers, 4 different subnets (first Byte): 185., 45., 64., 95., 4 different subnets (first two Bytes): 185.194., 45.83., 64.225., 95.217., 4 different subnets (first three Bytes): 185.194.141., 45.83.107., 64.225.78., 95.217.221.
AExcellent: Every Name Server IPv4-address starts with an unique Byte.
AInfo: IPv6-Subnet-list: 4 Name Servers with IPv6, 2 different subnets (first block): 2a01:, 2a03:, 3 different subnets (first two blocks): 2a01:04f9:, 2a03:4000:, 2a03:b0c0:, 4 different subnets (first three blocks): 2a01:04f9:c012:, 2a03:4000:001c:, 2a03:4000:0046:, 2a03:b0c0:0002:, 4 different subnets (first four blocks): 2a01:04f9:c012:68fb:, 2a03:4000:001c:0d2c:, 2a03:4000:0046:08ca:, 2a03:b0c0:0002:00f0:
AGood: Name Server IPv6 addresses from different subnets found.
AGood: Nameserver supports TCP connections: 8 good Nameserver
AGood: Nameserver supports Echo Capitalization: 8 good Nameserver
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 8 good Nameserver
AGood: All SOA have the same Serial Number
AGood: CAA entries found, creating certificate is limited: letsencrypt.org is allowed to create certificates
AGood: CAA entries found, creating certificate is limited: letsencrypt.org is allowed to create wildcard-certificates

4. Content- and Performance-critical Checks

https://www.tiekoetter.com/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de
403

Fatal: Check of /.well-known/acme-challenge/random-filename has a http status 401 / 403 Not Allowed / Forbidden. A http status 404 - Not Found - is expected. Creating a Letsencrypt certificate via http-01 challenge may not work. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
AGood: Every https result with status 200 and greater 1024 Bytes is compressed (gzip, deflate, br checked).
https://www.tiekoetter.com/ 152.53.125.158
200

Warning: Https result with status 200 found, Html-Content is too big. Should be max. 110 %. May contain inline CSS / JavaScript, too much comments or white space. Re-used ressources - create files with a long Cache-Control max-age header. Remove comments and white space.

AGood: Every https connection via port 443 supports the http/2 protocol via ALPN.
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
