If your computer is not yet connected
to a LAN, you also should skip this section.
Network address information is assigned to your computer in two basic ways: statically
(you type it) or dynamically (a DHCP server provides that information from the network
at boot time). One Network Device appears for each network card you have installed on
your computer. The first Ethernet interface is eth0, the second is eth1, and so on. Repeat
the setup for each card by selecting the card and clicking Edit.
Chapter 5 discusses IP addresses, netmasks, and other information you need to set up
your LAN.
With the Edit Interface eth0 dialog box displayed, add the following for both IPv4 and
IPv6 support:
Enable IPv4 support??”This is the most common TCP/IP protocol version in use
today. It should be enabled in most cases.
Dynamic IP configuration (DHCP)??”For IPv4 support, if your IP address is assigned
automatically from a DHCP server, a check mark should appear here. With DHCP
checked, you don??™t have to set IPv4 addresses on this page. Remove the check mark to
set your own IP address.
Enable IPv6 support??”This is the upcoming TCP/IP standard, which features much
longer addresses and some built-in security features. You can enable this without conflicting
with IPv4 support.
