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 Author and Publisher, The TCP/IP Guide

RFC Categories

As before, not all RFCs are official Internet standards, which is important to remember. Each RFC has a category or status associated with it that indicates its disposition:

• Proposed Standard / Draft Standard / Standard: These are documents that describe technologies said to be on the “standards track”. That means they are either already formally approved as standards, or they are likely to become standards in the future. In many cases, the document is just given as “Standards Track” as opposed to one of those three precise labels. See below for more information.
  
  
• Best Current Practice: A document providing guideline information or recommendations from the IETF that is not a formal standard.
  
  
• Informational: A document that provides general information or commentary.
  
  
• Experimental: A proposal for an experimental standard that is not on the standards track. In some cases, protocols or proposed changes to existing protocols that are not accepted as formal standards are changed to “experimental” status.
  
  
• Historic: Former standards that have been obsoleted.
