| 1. General Results, most used to calculate the result |
| A | name "mytel.com.mm" is domain, public suffix is ".*.mm", top-level-domain is ".mm", top-level-domain-type is "country-code", Country is Myanmar, tld-manager is "Ministry of Transport and Communications", num .mm-domains preloaded: 2 (complete: 276475)
|
| A | Good: All ip addresses are public addresses
|
| Warning: Only one ip address found: mytel.com.mm has only one ip address.
|
| Warning: Only one ip address found: www.mytel.com.mm 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: mytel.com.mm has no ipv6 address.

|
| A | Good: No asked Authoritative Name Server had a timeout
|
| A | Good: destination is https
|
| HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
|
| A | Good: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)
|
| B | https://mytel.com.mm/ 27.109.116.144
|
| Missing HSTS-Header
|
| B | https://www.mytel.com.mm/ 27.109.116.144
|
| Missing HSTS-Header
|
| C | Error - no preferred version www or non-www. Select one version as preferred version, then add a redirect https + not-preferred version to https + preferred version. Perhaps in your port 443 vHost something like "RewriteEngine on" + "RewriteCond %{SERVER_NAME} = example.com" + "ReWriteRule ^ https://www.example.com%{REQUEST_URI} [END,QSA,R=permanent]" (three rows, without the "). That should create a redirect https + example.com ⇒ https + www.example.com. Or switch both values to use the non-www version as your preferred version.
|
| C | Error - more then one version with Http-Status 200. After all redirects, all users (and search engines) should see the same https url: Non-www or www, but not both with http status 200.
|
| M | https://27.109.116.144/ 27.109.116.144
|
| Misconfiguration - main pages should never send http status 400 - 499
|
| N | https://27.109.116.144/ 27.109.116.144
|
| Error - Certificate isn't trusted, RemoteCertificateNameMismatch, RemoteCertificateChainErrors
|
| 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 different. So that domain requires Server Name Indication (SNI), so the server is able to select the correct certificate.: Domain mytel.com.mm, 1 ip addresses.

| 2. Header-Checks |
| A | mytel.com.mm 27.109.116.144
| Content-Security-Policy
| Ok: Header without syntax errors found: frame-ancestors 'none';
|
| F |
|
| Bad: Missing default-src directive. A default-src directive is used if one of the specialized fetch directives (child-src, connect-src, font-src, frame-src, img-src, manifest-src, media-src, object-src, prefetch-src, script-src, style-src, worker-src) isn't defined. Missing default-src, all sources are allowed, that's bad. A default-src with 'none' or 'self' blocks that.
|
| E |
|
| Bad: No form-action directive found. Use one to limit the form - action - destinations. form-action is a navigation-directive, so default-src isn't used.
|
| A |
|
| Good: frame-ancestors directive found. That limits pages who are allowed to use this page in a frame / iframe / object / embed / applet. frame-ancestors is a navigation-directive, so default-src isn't used.
|
| E |
|
| Bad: No base-uri directive found. Use one to limit the URLs which can be used in a document's <base> element. Because it's a document directive, default-src isn't used, so an own directive is required.
|
| F |
|
| Critical: No object-src and no default-src as fallback defined. So object / embed / applet can load every resource. That's fatal.
|
| F |
|
| Critical: No script-src and no default-src as fallback defined. So scripts are unlimited. That's fatal.
|
| A |
| X-Frame-Options
| Ok: Header without syntax errors found: DENY
|
| B |
|
| Info: Header is deprecated. May not longer work in modern browsers. DENY. Better solution: Use a Content-Security-Policy Header with a frame-ancestors directive. DENY - use 'none', SAMEORIGIN - use 'self'. If you want to allow some domains to frame your page, add these urls.

| 3. DNS- and NameServer - Checks |
| A | Info:: 2 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 2 Name Servers.
|
| A | Info:: 2 Queries complete, 1 with IPv6, 1 with IPv4.
|
| Warning: Only some DNS Queries done via ipv6. IPv6 is the future, so the name servers of your name servers should have ipv6 addresses.
|
| 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.mtalk.net.mm (103.47.185.210), ns2.mtalk.net.mm (202.157.134.58)
|
| 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:: 2 different Name Servers found: ns1.mtalk.net.mm, ns2.mtalk.net.mm, 2 Name Servers included in Delegation: ns1.mtalk.net.mm, ns2.mtalk.net.mm, 2 Name Servers included in 1 Zone definitions: ns1.mtalk.net.mm, ns2.mtalk.net.mm, 1 Name Servers listed in SOA.Primary: ns1.mtalk.net.mm.
|
| A | Good: Only one SOA.Primary Name Server found.: ns1.mtalk.net.mm.
|
| A | Good: SOA.Primary Name Server included in the delegation set.: ns1.mtalk.net.mm.
|
| 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.mtalk.net.mm, ns2.mtalk.net.mm
|
| 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: 2 different Name Servers found
|
| Warning: No Name Server IPv6 address found. IPv6 is the future, so your name servers should be visible via IPv6.: 2 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.: 2 Name Servers, 1 Top Level Domain: *.mm
|
| 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: net.mm
|
| A | Good: Name servers with different Country locations found: 2 Name Servers, 2 Countries: MM, SG
|
| A | Info: Ipv4-Subnet-list: 2 Name Servers, 2 different subnets (first Byte): 103., 202., 2 different subnets (first two Bytes): 103.47., 202.157., 2 different subnets (first three Bytes): 103.47.185., 202.157.134.
|
| A | Excellent: Every Name Server IPv4-address starts with an unique Byte.
|
| A | Good: Nameserver supports TCP connections: 2 good Nameserver
|
| A | Good: Nameserver supports Echo Capitalization: 2 good Nameserver
|
| A | Good: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 2 good Nameserver
|
| 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://mytel.com.mm/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 27.109.116.144
|
| 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 | Good: Every https connection via port 443 supports the http/2 protocol via ALPN.
|
| 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
