What the heck is DNS?

By | February 14, 2014

DNS stands for Donuts Not Salads. It’s a form of population control popularized by huge food cartels who, by adding chemicals to cardboard-like materials and then forming them into recognizable food items like Twinkies, Big Macs, and french fries, give you a heck of a lot of calories but very little nutrition. The object of this is to keep us fat and happy and make sure we don’t live much past 70 – thereby making way for new customers..err I mean people. The plot thickens…big corporations are controlling the population with Twinkies and so forth. DNS or Donuts Not Salads in an insidious campaign to keep us happy while we drop dead well before our time.

OUCH! Don’t slap me, EB. I was just funnin’.

The Internet Domain Name System Explained for Non-Experts by Daniel Karrenberg

DNS stands for Domain Name System, and without a lot of technical language it allows the Internet to name things so you don’t have to type in long numbers or arcane codes to access, let’s say Microsoft.com or Google or Thundercloud.net. It would be like if you could just dial EB on your phone and get connected to EB’s phone and then you could have instant access to a good scolding, instantly, anytime you want. If you have not done anything wrong, don’t worry, EB will find something you’ve done wrong even if she has to dig back four or five decades, she’ll dredge it up and beat you over the head with it. So it’s a good thing you have to dial a long series of numbers to reach her. I have her on my speed dial for instant access to good verbal spankings whenever I need one, which is apparently all the time 🙂

The purpose of the DNS is to enable Internet applications and their users to name things that have to have a globally unique name. The obvious benefit is easily memorizable names for things like web pages and mailboxes, rather than long numbers or codes. Less obvious but equally important is the separation of the name of something from its location. Things can move to a totally different location in the network fully transparently, without changing their name. www.isoc.org  can be on a computer in Virginia today and on another computer in Geneva tomorrow without anyone noticing.

In order to achieve this separation, names must be translated into other identifiers which the applications use to communicate via the appropriate Internet protocols. Let’s look at what happens when you send a mail message to me at (removed for privacy). A mail server trying to deliver the message has to find out where mail for mailboxes at ‘ripe.net’ has to be sent. This is when the DNS comes into play. The mail server transmits this question, called a ‘query’ in DNS terminology to the DNS. Quickly it receives as answer…

DNS is quite a fascinating subject. If you’d like to learn more about DNS, you can download the entire article in PDF format from this link.

      Yes, Michael, TC can’t help himself. I think he may be afraid he’ll hurt himself if he bites his tongue to often. Oh, ya! Ha Ha Ha! But truth be told, I love the old curmudgeon dearly. He often ‘makes my day’! As for EB…I don’t think she is anywhere near as bad as TC tells us she is. So, hang in there EB. You’re both invaluable to all of us. You both keep our computers humming…And our spirits giggling.
