Name server ( is recursive.

The name server answers recursive queries for 3rd parties (such as DNSCheck). By making a recursive query to a name server that provides recursion, an attacker can cause a name server to look up and cache information contained in zones under their control. Thus the victim name server is made to query the attackers malicious name servers, resulting in the victim caching and serving bogus data.

This is a cut and paste from pingdom. What does this all mean and why is this bad?

Thank you for your question iambriansreed!

A recursive <a href="" target="_blank">nameserver</a> will fetch DNS records for domains that are not contained in it. Our nameservers do not do that. You can test it by doing the following shell command.


Both fail, because we don't have in our nameservers. So in a nutrshell you don't have anything to worry about because our nameservers are not recursive. The Pingdom error is in error.

Im getting similar findings from another DNS testing site:

Open DNS (Recursion)
The following nameservers are advertising that they will perform recursive queries. That means that these nameservers will resolve any domain for anyone that asks. This can cause undue strain on the nameservers. This has also been used in the past with insecure nameservers to perform DNS Cache Poisoning attacks:

Just thought I'd let you know.
