Please Whitelist This Site?

I know everyone hates ads. But please understand that I am providing premium content for free that takes hundreds of hours of time to research and write. I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. And I have a family to support, just like you. :)

If you like The TCP/IP Guide, please consider the download version. It's priced very economically and you can read all of it in a convenient format without ads.

If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. To do so, just open the Adblock menu and select "Disable on tcpipguide.com". Or go to the Tools menu and select "Adblock Plus Preferences...". Then click "Add Filter..." at the bottom, and add this string: "@@||tcpipguide.com^$document". Then just click OK.

Thanks for your understanding!

Sincerely, Charles Kozierok

Usenet Overview, Concepts and General Operation

Where electronic mail is the modern equivalent of the hand-written letter or the inter-office memo, Usenet is the updated version of the company newsletter, the cafeteria bulletin board, the coffee break chat, and the water cooler gossip session, all rolled into one. Spread worldwide over the Internet, Usenet newsgroup messages provide a means for people with common interests to form online communities, to discuss happenings, solve problems, and provide support to each other—as well as facilitating plain old socializing and entertainment.

In this section I discuss Usenet as a whole and how it operates. I begin with an overview and history of Usenet. I then provide a high-level look at the model of communication employed by Usenet, discussing how messages are created, propagated, stored and read. I discuss the Usenet addressing mechanism, which takes the form of a hierarchical set of newsgroups. I also explain how Usenet messages are formatted and discuss the special headers that provide information about a message and control how it is displayed and communicated.
