0 DS RR in the parent zone found






DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "nh2jeethc53bso2f2s1hcr7bivnjichr" between the hashed NSEC3-owner "nesqltbul6frvj7qi0211bo30nncgbg8" and the hashed NextOwner "nhu6q0ob6ujci6dssketpefnuqqsqvk6". So the parent zone confirmes the not-existence of a DS RR.

7. Comments


1. General Results, most used to calculate the result

Aname "mail.samys.network" is subdomain, public suffix is "network", top-level-domain-type is "generic", tld-manager is "Binky Moon, LLC"
AGood: All ip addresses are public addresses
AGood: No asked Authoritative Name Server had a timeout
ADNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
AGood: destination is https
AGood - only one version with Http-Status 200
AGood: one preferred version: non-www is preferred
AGood: every cookie sent via https is marked as secure
AGood: every https has a Strict Transport Security Header
AGood: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)
Ahttp://mail.samys.network/ 188.40.182.16
301
https://mail.samys.network/
Correct redirect http - https with the same domain name
Ahttp://mail.samys.network/ 2a01:4f8:13b:2744::16

https://mail.samys.network/
Correct redirect http - https with the same domain name
BWarning: HSTS max-age is too short - minimum 31536000 = 365 days required, 15768000 seconds = 182 days found
XFatal error: Nameserver doesn't support TCP connection: demand.alpha.aridns.net.au: Fatal error (-14). Details: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. - An existing connection was forcibly closed by the remote host

2. Header-Checks (Cross-Origin-* headers are alpha - started 2024-06-05)


3. DNS- and NameServer - Checks

AGood: Nameserver supports TCP connections: 2 good Nameserver
AGood: Nameserver supports Echo Capitalization: 2 good Nameserver
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 2 good Nameserver
AGood: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 2 good Nameserver
Nameserver doesn't pass all EDNS-Checks: demand.beta.aridns.net.au: 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 (dns3.ams). COOKIE: fatal timeout. CLIENTSUBNET: ok.

NSID: SOA expected, but NOT found, NOERR expectend and NOERR found, Version 0 expectend and found (dns2.ams). COOKIE: fatal timeout. CLIENTSUBNET: ok.
Nameserver doesn't pass all EDNS-Checks: ns2.domainoffensive.de: 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.
AGood: 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

AGood: All checks /.well-known/acme-challenge/random-filename without redirects answer with the expected http status 404 - Not Found. Creating a Letsencrypt certificate via http-01 challenge should work. If it doesn't work: Check your vHost configuration (apachectl -S, httpd -S, nginx -T). Every combination of port and ServerName / ServerAlias (Apache) or Server (Nginx) must be unique. Merge duplicated entries in one vHost. If you use an IIS, extensionless files must be allowed in the /.well-known/acme-challenge subdirectory. Create a web.config in that directory. Content: <configuration><system.webServer><staticContent><mimeMap fileExtension="." mimeType="text/plain" /></staticContent></system.webServer></configuration>. If you have a redirect http ⇒ https, that's ok, Letsencrypt follows such redirects to port 80 / 443 (same or other server). There must be a certificate. But the certificate may be expired, self signed or with a not matching domain name. Checking the validation file Letsencrypt ignores such certificate errors. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
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
