Another DNS checker

I’ve found an even better site that can check your DNS for recent vulnerability issues.

https://www.dns-oarc.net/oarc/services/dnsentropy 

Will produce results like:



Which provide plenty of information in a nice to understand graphics nature. You should run this test to see whether the DNS servers you are using (usually from your ISP) have been patched to overcome a recent DNS vulnerability.

However, I would strongly suggest you consider using www.opendns.com as an alternative DNS resolver for so many other reasons as well.
