This
document is a brief introduction to TCP/IP,
followed by advice on what to read for more
information. This is not intended to be a complete
description. It can give you a reasonable idea of
the capabilities of the protocols. But if you need
to know any details of the technology, you will
want to read the standards yourself. Throughout
the text, you will find references to the
standards, in the form of "RFC" or "IEN" numbers.
These are document numbers. The final section of
this document tells you how to get copies of those
standards.
