| A | Good: More then one ip address per domain name found, checking all ip addresses the same http status and the same certificate found: Domain mozilla.map.fastly.net, 2 ip addresses.
|
| Info: Checking all ip addresses of that domain without sending the hostname only one certificate found. Checking all ip addresses and sending the hostname only one certificate found. Both certificates are the same. So that domain doesn't require Server Name Indication (SNI), it's the primary certificate of that set of ip addresses.: Domain mozilla.map.fastly.net, 2 ip addresses, 1 different http results.

| 3. DNS- and NameServer - Checks |
| A | Info:: 2 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 4 Name Servers.
|
| A | Info:: 2 Queries complete, 2 with IPv6, 0 with IPv4.
|
| A | Good: All DNS Queries done via IPv6.
|
| A | Good: 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.fastly.net (23.235.32.32), ns2.fastly.net (104.156.80.32), ns3.fastly.net (23.235.36.32), ns4.fastly.net (104.156.84.32)
|
| A | Good (1 - 3.0):: An average of 0.5 queries per domain name server required to find all ip addresses of all name servers.
|
| A | Info:: 4 different Name Servers found: ns1.fastly.net, ns2.fastly.net, ns3.fastly.net, ns4.fastly.net, 4 Name Servers included in Delegation: ns1.fastly.net, ns2.fastly.net, ns3.fastly.net, ns4.fastly.net, 4 Name Servers included in 1 Zone definitions: ns1.fastly.net, ns2.fastly.net, ns3.fastly.net, ns4.fastly.net, 1 Name Servers listed in SOA.Primary: ns1.fastly.net.
|
| A | Good: Only one SOA.Primary Name Server found.: ns1.fastly.net.
|
| A | Good: SOA.Primary Name Server included in the delegation set.: ns1.fastly.net.
|
| A | Good: 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.fastly.net, ns2.fastly.net, ns3.fastly.net, ns4.fastly.net
|
| A | Good: All Name Server Domain Names have a Public Suffix.
|
| A | Good: All Name Server Domain Names ending with a Public Suffix have minimal one IPv4- or IPv6 address.
|
| A | Good: All Name Server ip addresses are public.
|
| A | Good: Minimal 2 different name servers (public suffix and public ip address) found: 4 different Name Servers found
|
| Warning: No Name Server IPv6 address found. IPv6 is the future, so your name servers should be visible via IPv6.: 4 different Name Servers found
|
| Warning: All Name Servers have the same Top Level Domain / Public Suffix. If there is a problem with that Top Level Domain, your domain may be affected. Better: Use Name Servers with different top level domains.: 4 Name Servers, 1 Top Level Domain: net
|
| Warning: All Name Servers have the same domain name. If there is a problem with that domain name (or with the name servers of that domain name), your domain may be affected. Better: Use Name Servers with different domain names / different top level domains.: Only one domain name used: fastly.net
|
| Warning: All Name Servers from the same Country / IP location.: 4 Name Servers, 1 Countries: CA
|
| A | Info: Ipv4-Subnet-list: 4 Name Servers, 2 different subnets (first Byte): 104., 23., 2 different subnets (first two Bytes): 104.156., 23.235., 4 different subnets (first three Bytes): 104.156.80., 104.156.84., 23.235.32., 23.235.36.

|
| A | Good: CAA entries found, creating certificate is limited: certainly.com is allowed to create certificates
|
| A | Good: CAA entries found, creating certificate is limited: globalsign.com is allowed to create certificates
|
| A | Good: CAA entries found, creating certificate is limited: letsencrypt.org is allowed to create certificates
|
| Warning: Unknown CAA found: certainly.com isn't defined. Unknown entry. May be wrong written, may be not longer valid. May be a missing entry in this tool.

|
| Fatal: Check of /.well-known/acme-challenge/random-filename has a http status between 400 and 499, but not 404 - Not Found. Creating a Letsencrypt certificate via http-01 challenge may not work. 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
