RFCs of Historical Interest

The Hitchhikers Guide to the Internet

The hitchhikers guide to the Internet is a very unevenly edited memo and contains many passages which simply seemed to its editors like a good idea at the time. It is an indispensable companion to all those who are keen to make sense of life in an infinitely complex and confusing Internet, for although it cannot hope to be useful or informative on all matters, it does make the reassuring claim that where it is inaccurate, it is at least definitively inaccurate. In cases of major discrepancy it is always reality that's got it wrong. And remember, DON'T PANIC. (Apologies to Douglas Adams.)

The "Lighter Side"

SONET to Sonnet Translation

Definitions of Managed Objects for Drip-Type Heated Beverage Hardware Devices using SMIv2

This memo defines an extension to the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it defines objects for the management of coffee-brewing and maintenance devices.

Hyper Text Coffee Pot Control Protocol (HTCPCP/1.0)

There is coffee all over the world. Increasingly, in a world in which computing is ubiquitous, the computists want to make coffee. Coffee brewing is an art, but the distributed intelligence of the web-connected world transcends art. Thus, there is a strong, dark, rich requirement for a protocol designed espressoly for the brewing of coffee. Coffee is brewed using coffee pots. Networked coffee pots require a control protocol if they are to be controlled.

RITA -- The Reliable Internetwork Troubleshooting Agent

A Description of the usage of Nondeterministic Troubleshooting and Diagnostic Methodologies as applied to today's complex nondeterministic networks and environments.

The Naming of Hosts

This RFC is a commentary on the difficulty of deciding upon an acceptably distinctive hostname for one's computer, a problem which grows in direct proportion to the logarithmically increasing size of the Internet.

The Twelve Networking Truths

This memo documents the fundamental truths of networking for the Internet community.
