Check DNS, Urls + Redirects, Certificates and Content of your Website


Info: Problems with 3.048.289 Letsencrypt certificates (378.325 accounts). They must be revoked (revocation starts 2020-03-04 20:00 UTC) - see Revoking certain certificates on March 4. Update 2020-03-07: Good news: Mass-revocation is canceled.

This tool: A check (SerialNumber) is added. Letsencrypt has published a list of critical SerialNumbers, this list is checked. See the part "9. Certificates". If there is a warning, renew that certificate and replace the current certificate.

Info: The Xml-split has triggered some hidden bugs. Now it looks ok.
If root or the top level zone isn't validated, it's buggy.

0 DS RR in the parent zone found



DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed domain name between the hashed NSEC3-owner and the hashed NextOwner. So the parent zone confirmes the non-existence of a DS RR.Bitmap: NS, DS, RRSIG

7. Comments


1. General Results, most used to calculate the result

Aname "colnbase.design" is domain, public suffix is "design", top-level-domain-type is "generic", tld-manager is "Top Level Design, LLC"
Agood: No asked Authoritative Name Server had a timeout
ADNS: "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.

2. DNS- and NameServer - Checks

AGood: 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: ns1.digitalocean.com,ns2.digitalocean.com,ns3.digitalocean.com
AGood: Nameserver supports TCP connections: 6 good Nameserver
AGood: Nameserver supports Echo Capitalization: 6 good Nameserver
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 6 good Nameserver
AGood: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 6 good Nameserver
Nameserver doesn't pass all EDNS-Checks: ns1.digitalocean.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.
AGood: All SOA have the same Serial Number
Agood: CAA entries found, creating certificate is limited: letsencrypt.org is allowed to create certificates

3. Content- and Performance-critical Checks

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

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" > 2019 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


12. Nameserver - IP-Adresses (alpha)

Required Root-climbing DNS-Queries to find ip addresses of all Name Servers:

No NameServer - IP address informations found. The feature is new (2020-05-07), so recheck this domain.
