Correct, but every machine has a host name.

you can try to 'hi-jack' the ip by doing this trick, you may need
an extra machine if the lease is less than 1 min (time needed to
reconfigure your machine to static and stop dhcp on client):
1. use a machine running client dhcp and start it up, examine what
ip address obtained, and write it down. If the ip lease is over
5min, you have sufficient time to reconfigure your machine to
static ip using this ip address. Immediately restart net service
and you are now static. @home DHCP server won't re-assign this
ip address to any other machine.
2. If the lease obtained from the server is less than 1min, (most
servers offer much longer lease time), you can do this:
Prepare to machines, one is dhcp client, and other one static,
put the dhcp client machine on-line first, once obtained a ip
from the dhcp server, immediately put this ip address to the
other standby machine and disconnect the dhcp client machine,
then connect the static machine. boom, you have hi-jacked the
ip and you are online static. The server has no way to change
or stop your using that ip.
