• 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.
