networks not using IPv6 protocol, response times can be faster with IPv6 protocol dis-
abled. If you want to disable IPv6, uncheck the Enable IPv6 option. This disables au-
toload of the kernel module for IPv6. This will be applied after reboot.
In the DHCP Client Options configure options for the DHCP client. If you want the
DHCP client to ask the server to always broadcast its responses, check Request
Broadcast Response. It may be needed if your machine is moving between different
networks. The DHCP Client Identifier must be different for each DHCP client on a
single network. If left empty, it defaults to the hardware address of the network interface.
However, if you are running several virtual machines using the same network interface
and, therefore, the same hardware address, specify a unique free-form identifier here.
The Hostname to Send specifies a string used for the hostname option field when dhcpcd
sends messages to DHCP server. Some DHCP servers update name server zones (forward
and reverse records) according to this hostname (Dynamic DNS). Also, some DHCP
servers require the Hostname to Send option field to contain a specific string in the
DHCP messages from clients. Leave AUTO to send the current hostname (that is the
one defined in /etc/HOSTNAME). Leave the option field empty for not sending any
hostname. If yo do not want to change the default route according to the information
from DHCP, uncheck Change Default Route via DHCP.
Changing the Configuration of a Network Card
To change the configuration of a network card, select a card from the list of the detected
cards in Network Settings > Overview in YaST and click Edit. The Network Card Setup
dialog appears in which to adjust the card configuration using the General, Address
and Hardware tabs. For information about wireless card configuration, see Sec-
tion 18.1.2, "Configuration with YaST" (page 263).
Configuring IP Addresses
You can set the IP address of the network card or the way its IP address is determined
in the Address tab of the Network Card Setup dialog. Both IPv4 and IPv6 addresses are
supported. The network card can have No IP Address (which is useful for bonding de-
vices), a Statically Assigned IP Address (IPv4 or IPv6) or a Dynamic Address assigned
via DHCP and/or Zeroconf.
If using Dynamic Address, select whether to use DHCP Version 4 Only (for IPv4),
DHCP Version 6 Only (for IPv6) or DHCP Both Version 4 and 6.
