Simple dhcp configuration

[Absurd]

I'm a complete dummy (or even lamer) in networking stuff, but today I had to set DHCP service in my Fedora in order to give access to internet from my girl's laptop w/o need to configure static IP. So i've taken a most simpliest configuration draft from the Net and changed IPs there. Seems like it works, but i'm not sure is anything correct. Particularly, i thought that server-identifier is useless entity just to give name to this rig. However, there are some non-fatal errors in system log. What should i put there?


server-identifier absurd;

subnet 192.168.0.0 netmask 255.255.255.0 {
authoritative;
range 192.168.0.2 192.168.0.250;
