What’s Domain Name Service?

The domain name server ensures that you always end up on the right website.  All websites have an address, this address is a set of numbers called the IP.  The DNS resolves IP addresses to website names.  So instead of typing 193.5.2.1 you can just enter http://www.yourfavoritesite.com.

Domain Name Service Poisoning

When a DNS server is posioned it redirects you.  Meaning instead of you going to google.com you’ll end up on whatever site the hacker wants you to go to.  This happens due to the hacker replacing the DNS records of the server.  To prevent this ensure your antivirus protection is up to date.  Also stay away from anyway site that isn’t mom approved.
