• If you have a static IP address, enter
static in the BOOTPROTO= field. Type IPADDR= followed
by the IP address (in dotted decimal notation) and type NETMASK= followed by the subnet
mask. The following example shows an example where the static IP address is 192.168.1.10
and the subnet mask is 255.255.255.0.
