Finding your computer name for netconfig

Hello, new here. I have Slackware 14.2 installed on a old laptop. I need to find the computer name to configure a dhcp connection. I have configure rc.inet1.conf.

IPADDRR[0]=""
NETMASK[0]=""
USE_DHCP[0]="yes"
DHCP_HOSTNAME[0]" This is where I need to put the computer name.<-----

This is the last setting when I use netconfig.

Thanks in advance..
