6 - Networking
6.1 - Before we go any further
For the bulk of this document, it helps if you have read and at least partially understood the 
Kernel 
Configuration and Setup
 section of the FAQ, and the 
ifconfig(8)
and 
netstat(1)
man pages. 
If you are a network administrator, and you are setting up routing protocols, if you are using your 
OpenBSD box as a router, if you need to go in depth into IP networking, you really need to read 
Understanding IP Addressing
. This is an excellent document. "Understanding IP Addressing" contains 
fundamental knowledge to build upon when working with IP networks, especially when you deal with or 
are responsible for more than one network. 
If you are working with applications such as web servers, ftp servers, and mail servers, you may benefit 
greatly by 
reading the RFCs
. Most likely, you can't read all of them. Pick some topics that you are 
interested in, or that you use in your network environment. Look them up, find out how they are 
intended to work. The RFCs define many (thousands of) standards for protocols on the Internet and how 
they are supposed to work.
