The DHCP package is not used in RH8.0,9.0, and the DHCLIENT package which is
being used in its place does not send releases when the system is shutdown.

How reproducible:
Always

Steps to Reproduce:

information to the IP.  IP was never released.

Comment 2 Daniel Walsh 2003-04-11 19:32:54 UTC

From the Man page:

 The  client  normally  doesnÃ¢t  release  the current lease as it is not
 required by the DHCP protocol.  Some cable ISPs require  their  clients
 to  notify  the  server if they wish to release an assigned IP address.
 The -r flag explicitly releases the current lease, and once  the  lease
 has been released, the client exits.

so running 
/sbin/dhclient -r -lf /var/lib/dhcp/dhclient-eth0.leases -pf
/var/run/dhclient-eth0.pid

should release the eth0 device.
