• If you have a static IP address, enter 

 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.

2 If you know your DNS server IP address(es), enter the DNS server information in the 

resolv.conf

 file in the 

/etc

 directory.  The following figure shows an example where 

two DNS server IP addresses are specified.

3 After you edit and save the configuration files, you must restart the network card. Enter 

./network restart

 in the 

/etc/rc.d/init.d 

directory.  The following figure 

shows an example.
