Does your DNS still have flaws?

Late the week, I’ve had some concern with the DNS flaws with my ISP.  So I’ve change to another DNS.  So I went and did a test at:

Doxpara

So what does this mean when it says I might be at risk?

Very simple, your DNS provider is not randomizing the ports.  I’ll get to that in a bit.

What is DNS?

The DNS is like a big Phonebook to where you tell it who you want to call, in this case go, and it finds the numbers and takes you there.  It’s like telling a cab driver where you want to visit, just like telling the cab driver to come to my site.  When you enter http://www.tech-linkblog.com into your browser, your telling DNS to go fetch the ip and direct your connection to this site.

So how can I fix this flaw?

Simple, You will need to direct yourself to OpenDNS.  Has Fixed the flaw to help protect you.  How do you use it?  You will tell your system to direct all the DNS queries through that then your ISP DNS.

So by using the openDNS, you will be bypassing the DNS flaws that you might of have. If you want to use that DNS server go to there website and it tells you step by step on how to do it with your own system.

The Nice thing about OpenDNS is they have so many features,  You can prevent phishing, adult sites, Domain blocking, and much more.  If you use this, you can prevent you kids from getting on the sites that you don’t want them to get on.  It lets you have control over what you want to do.  I recommend people to use OpenDNS.
