www.foto.stalpers-net.nl	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 "ppf73t1dln2avplk4mj7u03ll93g98pq" between the hashed NSEC3-owner "mr46tp3h5qirm7rg63uuk4r625f1bop8" and the hashed NextOwner "uv7ng645bvoa8qufbcogac8f7h5le8mu". So the parent zone confirmes the not-existence of a DS RR. Bitmap: CNAME, RRSIG Validated: RRSIG-Owner mr46tp3h5qirm7rg63uuk4r625f1bop8.stalpers-net.nl., Algorithm: 8, 3 Labels, original TTL: 60 sec, Signature-expiration: 16.02.2026, 06:52:07 +, Signature-Inception: 17.01.2026, 06:52:07 +, KeyTag 23446, Signer-Name: stalpers-net.nl


	DS-Query in the parent zone sends valid NSEC3 RR with the Hash "btllnjk7dnvn02f19udllte1spk0d50b" as Owner. That's the Hash of "foto.stalpers-net.nl" with the NextHashedOwnerName "coe7qtjlmc117hd3tulpohcmmqu7tfi7". So that domain name is the Closest Encloser of "www.foto.stalpers-net.nl". Opt-Out: False. Bitmap: CNAME, RRSIG Validated: RRSIG-Owner btllnjk7dnvn02f19udllte1spk0d50b.stalpers-net.nl., Algorithm: 8, 3 Labels, original TTL: 60 sec, Signature-expiration: 16.02.2026, 06:52:07 +, Signature-Inception: 17.01.2026, 06:52:07 +, KeyTag 23446, Signer-Name: stalpers-net.nl


	The ClosestEncloser says, that "*.foto.stalpers-net.nl" with the Hash "1oj1eec9pk7h3jhvlc6ps1d42kj01l8i" is a possible Wildcard of the DS Query Name. But the DS-Query in the parent zone sends a valid NSEC3 RR With the owner "uv7ng645bvoa8qufbcogac8f7h5le8mu" and the Next Owner "2h1d2918oc9nat1jeva8t18lb5i1lo1d", so the Hash of the wildcard is between these hashes. So that NSEC3 proves the Not-existence of that wildcard expansion. Opt-Out: False.

A	Info: IPv6-Subnet-list: 2 Name Servers with IPv6, 1 different subnets (first block): 2001:, 1 different subnets (first two blocks): 2001:41d0:, 2 different subnets (first three blocks): 2001:41d0:0b00:, 2001:41d0:0d00:, 2 different subnets (first four blocks): 2001:41d0:0b00:f200:, 2001:41d0:0d00:f800:
A	Good: Name Server IPv6 addresses from different subnets found.
A	Good: Nameserver supports TCP connections: 4 good Nameserver
A	Good: Nameserver supports Echo Capitalization: 4 good Nameserver
A	Good: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 4 good Nameserver
A	Good: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 4 good Nameserver
	Nameserver doesn't pass all EDNS-Checks: dns19.ovh.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: 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
	http://foto.stalpers-net.nl/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 135.125.181.66	-14	Fatal: Check of /.well-known/acme-challenge/random-filename has a timeout. Creating a Letsencrypt certificate via http-01 challenge can't work. You need a running webserver (http) and an open port 80. If it's a home server + ipv4, perhaps a correct port forwarding port 80 extern ⇒ working port intern is required. Port 80 / http can redirect to another domain port 80 or port 443, but not other ports. If it's a home server, perhaps your ISP blocks port 80. Then you may use the dns-01 challenge. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.

A	Info: No img element found, no alt attribute checked
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
