| 1. General Results, most used to calculate the result |
| A | name "speedtest1unn.brunet.bn" is subdomain, public suffix is ".bn", top-level-domain is ".bn", top-level-domain-type is "country-code", Country is Brunei Darussalam, tld-manager is "Authority for Info-communications Technology Industry of Brunei Darussalam (AITI)", num .bn-domains preloaded: 1 (complete: 244198)
|
| A | Good: All ip addresses are public addresses
|
| Warning: Only one ip address found: speedtest1unn.brunet.bn has only one ip address.
|
| Warning: No ipv6 address found. Ipv6 is the future with a lot of new features. So every domain name should have an ipv6 address. See https://en.wikipedia.org/wiki/IPv6: speedtest1unn.brunet.bn has no ipv6 address.
|
| A | Good: No asked Authoritative Name Server had a timeout
|
| A | DNS: "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.
|
| N | speedtest1unn.brunet.bn:8080
|
| Error - Certificate isn't trusted, RemoteCertificateNameMismatch, RemoteCertificateChainErrors
|
| O | speedtest1unn.brunet.bn / 202.160.29.218 / 8080
|
| Old connection: Cipher Suites without Forward Secrecy (FS) found. Remove all of these Cipher Suites, use only Cipher Suites with Forward Secrecy: Starting with ECDHE- or DHE - the last "E" says: "ephemeral". Or use Tls.1.3, then all Cipher Suites use FS. 2 Cipher Suites without Forward Secrecy found
|
| X | Fatal error: Nameserver doesn't support TCP connection: te02.brunet.bn / 61.6.254.204: Timeout
|
| Info: Checking the ip addresses of that domain name not exact one certificate found. So it's impossible to check if that domain requires Server Name Indication (SNI).: Domain speedtest1unn.brunet.bn, 1 ip addresses.
|
| B | No _mta-sts TXT record found (mta-sts: Mail Transfer Agent Strict Transport Security - see RFC 8461). Read the result of server-daten.de (Url-Checks, Comments, Connections and DomainServiceRecords) to see a complete definition. Domainname: _mta-sts.speedtest1unn.brunet.bn
|

|
| 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.pt01.brunet.bn (61.6.254.201), pt02.brunet.bn (61.6.254.202)
|
| A | Good (1 - 3.0):: An average of 1.0 queries per domain name server required to find all ip addresses of all name servers.
|
| A | Info:: 3 different Name Servers found: pt01.brunet.bn, pt02.brunet.bn, te02.brunet.bn, 2 Name Servers included in Delegation: pt01.brunet.bn, pt02.brunet.bn, 2 Name Servers included in 2 Zone definitions: pt01.brunet.bn, pt02.brunet.bn, 1 Name Servers listed in SOA.Primary: te02.brunet.bn.
|
| A | Good: Only one SOA.Primary Name Server found.: te02.brunet.bn.
|
| Error: SOA.Primary Name Server not included in the delegation set.: te02.brunet.bn.
|
| A | Good: All Name Server Domain Names have a Public Suffix.
|
| Error: Name Server Domain Names with Public Suffix and without ip address found.: 1 Name Servers without ipv4 and ipv6: 1
|
|
|
| A | Info: Ipv4-Subnet-list: 2 Name Servers, 1 different subnets (first Byte): 61., 1 different subnets (first two Bytes): 61.6., 1 different subnets (first three Bytes): 61.6.254.
|
| X | Fatal: All Name Server IPv4 addresses from the same subnet. Check https://www.iana.org/help/nameserver-requirements to learn some basics about name server configurations. If you manage these name servers, fix it. If it's your provider, change your provider.:

|
| 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://speedtest1unn.brunet.bn/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 202.160.29.218
|
| Fatal: Check of /.well-known/acme-challenge/random-filename is blocked, http connection error. 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
