DNSSEC analysis not possible on an IP

DNS servers IP are in different class C

IPs have the same C class.

The class C of each IP must be different so that the servers are not found on the same bay and therefore there is a risk of unavailability.

The Bind version should not be visible otherwise it will be possible to search for potential security vulnerabilities of the version.

0.046s

Domain have at least 2 DNS servers

Passed

In order for the availability rate of DNS servers to be at its highest, it is vital and recommended by the RFC to have at least 2 servers.

RFC

0.000s

All Dns servers are responding

Passed

Every DNS servers should be accessible and accept public query.

0.007s

All servers return success

Passed

It's important that all servers returned a "success" code.

0.007s

Responses are not CNAME or A

Passed

The answers should not be a CNAME or A type.

RFC

0.007s

DNS servers IP are differents

Passed

IPs for DNS servers must be different in order to have high availability.

0.000s

SOA are synchronized

Passed

The SOA answered by the DNS servers must be identical for each servers. The most important information is the master server and the contact email address.

0.000s

SOA email is valid

An email address must respect some conditions to be valid, accordding to the RFC 5322.

RFC

0.000s

SOA refresh is valid

RFC

0.000s

SOA retry, refresh and expire values are correct

Passed

The Retry, Refresh and Expire values musth follow this path : retry < refresh < expire.

RFC

0.000s

DNS servers are not open relay

Passed

DNS resolvers that allow queries from all IP addresses and are exposed to the Internet can be attacked and used to conduct Denial of Service (DoS) attacks on behalf of the hacker.

0.048s

Transfer zone is disable

Passed

An attacker can use a zone transfer that contains a malicious code or an inappropriate format that crashes a DNS server vulnerable to this type of attack, which results in a DoS that destabilizes the DNS services. It is possible to test it manually with this commands: #host -T axfr or #dig axfr.

documentation

0.141s

Recursive query is disable

Passed

Having a dns server that allow recursive queries is a security risk, DDOS attack can be performed.

RFC documentation documentation

0.045s

DNS servers IP are not private

Passed

It is strictly forbidden to have private IP in DNS

documentation

0.000s

DNS servers are synchronized

Skipped

The synchronization of the DNS servers must be perfect in order to avoid any dns resolution error. The servers must therefore give the same answer when asked "what are the DNS servers for the domain?".

Content Security Policy header is present

Skipped

The HTTP Content-Security-Policy response header allows web site administrators to control resources the user agent is allowed to load for a given page. With a few exceptions, policies mostly involve specifying server origins and script endpoints. This helps guard against cross-site scripting attacks (XSS).

Content Type Options header is present

Skipped

The only defined value, "nosniff", prevents Internet Explorer from MIME-sniffing a response away from the declared content-type. This also applies to Google Chrome, when downloading extensions.
