More often than not, when I tell people what the company that I work for does, they look at me with a blank stare and a trivial look on their face and say DNS, What… They still seem utterly confused after I try to explain what DNS is and how they are most likely using it everyday. These people usually just pretend like they get it and walk away, but do they really get it and what’s so hard to “get”?
We have touched on what DNS is quite a few times, but we still get the inevitable comments on surveys and blog posts that people are still very confused. One person actually compared DNS to buying a bottle of air, open it and there is nothing inside, but that couldn’t be further from the truth!
DNS redirects an IP address, to a static domain name. So if you want to visit www.no-ip.com, you type the domain name into your browser, not the IP address. If not for DNS, you would have to remember every IP address of every website! With over 300 million websites on the web, remembering every IP address would be utterly impossible, well unless maybe you’re Kim Peek: The Real Rain Man.
In addition, the transition to IPv6 will make remembering IP addresses even harder! IPv6 addresses are 128 bits long compared to 32 bits of Ipv4 addresses.
They look something like this: 2001:db8:0:1234:0:567:8:1. That’s a lot if numbers to remember! (I can barely remember my phone number!)
So, next time someone asks you, WHAT the heck is DNS?! You can tell them that it is indeed more than just bottle air. It makes visiting websites by a domain name, possible!
