This site covers Linux networking specific topics. It does not cover general networking questions, these are covered under the more general Wikipedia Computer Networks. See the External Links section for other useful resources.

Q: Why can I ping an IP address when the interface is down?
A: Linux uses a "host based" addressing model, IP addresses are owned by the host, not individual interfaces. So as long as the IP address is configured to some interface, we will accept packets destinated to that IP address as our's.
Please refer to the Ethernet page for more up to date information. This page is ancient and some love could be used to organize this information a little better under the ethernet section

The Spanning Tree Protocol (STP) is used to allow multiple bridges to work together. Each bridge communicates with other bridges to discover how they are interconnected. This information is then used to eliminate cycles, and provide optimal routing of packets. STP also provides fault tolerance, because it will recompute the topology if a bridge or port fails.
This page has heresay or limited information and may needs a more analytic basis
Provide a listing of motherboards and how well they are supported.
If work-arounds are needed, for example, disabling ACPI, or tweaking the BIOS, that information is welcome here.

A collection of programs that form the base set of the NET-3 networking distribution for the Linux operating system. This package includes arp(8), hostname(1), ifconfig(8), ipmaddr, iptunnel, mii-tool(8), nameif(8), netstat(8), plipconfig(8), rarp(8), route(8) and slattach(8).
ethtool is a Linux net driver diagnostic and tuning tool for the Linux 2.4.x (or later) series of kernels. Obtain information and diagnostics related to media, link status, driver version, PCI (or other) bus location, and more.

For example you have 2 links to ISP, one is 64Kbit and another is metered (you pay for traffic) much higher speed.
Latency of links must be very similar, otherwise in this example, packets from one session can come in different order to final destination!
I think the FAQ should be its own page linked to from the main page. Like this FAQ -Jon

TIPC is a LAN protocol, originally designed by Jon Maloy at Ericsson. Its purpose is to provide an efficient, transparent, and scalable communication mechanism for a wide range of possible cluster configurations. It has been in the linux kernel since 2.6.16.
