If you are using DHCP to get an IP address, the hostname of your computer will
be automatically set by the DHCP. You may want to disable this behavior if you
connect to different networks, because they may assign different hostnames and
changing the hostname at runtime may confuse the graphical desktop. To disable
using DHCP to get an IP address uncheck Change Hostname via DHCP.
If you are using DHCP to get an IP address, your hostname will be written to

disable this uncheck Write Hostname to /etc/hosts but note that your hostname

If the Use Default Policy option is selected, the configuration is handled by the
netconfig script which merges the data defined statically (with YaST or in
the configuration files) with data obtained dynamically (from the DHCP client
or NetworkManager). This default policy is sufficient in most cases.
If the Only Manually option is selected, netconfig is not allowed to modify
the /etc/resolv.conf file. However, this file can be edited manually.
If the Custom Policy option is selected, a Custom Policy Rule string defining the
merge policy should be specified. The string consists of a comma-separated list
of interface names to be considered a valid source of settings. Except for complete
interface names, basic wildcards to match multiple interfaces are allowed, as
well. For example, eth* ppp? will first target all eth and then all ppp0-ppp9
interfaces. There are two special policy values that indicate how to apply the
static settings defined in the /etc/sysconfig/network/config file:

The static settings have to be merged together with the dynamic settings.
