How to obtain another IP address from DHCP server

My linux machine obtains IP address by DHCP. Anyway, I just want to know how to obtains another IP address rather than the current one from DHCP server?

Thank you.

I spoof my mac every time I reboot so I get new ip.
New mac = new ip.

Code:

#!/bin/sh
#********************************************************************************
# AUTO MAC SPOOF
# BY: THEGREATVIRUS
# Usage: macspoof <device>
## BASE SETTINGS
INTERFACE="ath0"
MAC="$(od -An -t x1 -N 5 /dev/urandom | sed 's/^/00/;s/ /:/g;q')"

if [ "$#" -eq 1 ]; then
	INTERFACE="$1"
fi

## MAC SPOOF
if [ "$INTERFACE" = "ath0" ]; then
	ifconfig $INTERFACE down >/dev/null
	wlanconfig $INTERFACE destroy >/dev/null
	ifconfig wifi0 hw ether $MAC >/dev/null
	wlanconfig $INTERFACE create wlandev wifi0 wlanmode managed >/dev/null
	ifconfig $INTERFACE up >/dev/null
else
	ifconfig $INTERFACE down >/dev/null
	ifconfig $INTERFACE hw ether $MAC >/dev/null
	ifconfig $INTERFACE up
fi

## OUTPUT
echo "Using Device: $INTERFACE"
echo ""
ifconfig $INTERFACE
echo DEVICE: $INTERFACE MAC: $MAC STATUS: UP

there is no any single command can do so?

Why would you need to obtain another IP address?

There really isn't, no...You can assign your NIC a static IP address if you don't like the one that your DHCP server is assigning you, but the point of a DHCP server is that it assigns IP addresses as it sees fit. You can't really say "No thanks, I don't think I like this one, give me another."
