What is DNS and DNSSEC?

Each web site has an "IP address", a long ID number that computers use to find the web site. Long numbers are hard to remember, and therefore we use domain names. Domain Name System (DNS) is a special system to translate between numbers and domain names.

Unfortunately, it is possible to exploit weaknesses in this system. criminals can divert Internet users attempting to reach a site, or they can intercept emails. DNSSEC is a signing method that can make the DNS more secure. it can for example avoid attacks by hackers who try to redirect traffic to malicious websites.
