[CentOS] DHCP_HOSTNAME in ifcfg-eth0

Is there a way for the dhcp client to send the current host name of the 
machine when requesting a lease ?

Currently I have to include a line like
in my /etc/sysconfig/network-scripts/ifcfg-eth0, but I would like to 
tell the dhcp client to just 'also send the hostname' and then the 
client to get the current hostname itself, instead of having the name 
hard-coded in the ifcfg-eth0 file.

I am trying to get my router to know the names of all my CentOS 
machines, as currently I can access none of my CentOS machines by their 
node name (I get 'unknown host' upon name lookup) and maybe it will help 
if the router knows all the computer names.

Thank you,
Timothy Madden
