No need, it's just straight-up DHCP.

bj@morpheus:~$ grep -v -e ^# -e ^$ /etc/dhclient.conf
request subnet-mask, broadcast-address, time-offset, routers,
        domain-name, host-name;
require subnet-mask;
supersede domain-name-servers 127.0.0.1;
append domain-name " billjonas.com";
timeout 60;

There was lots of commented-out stuff that came with the file, which is
why that grep is there.  Also, I'm doing some stuff like running my own
DNS server for my internal LAN, so there's other stuff in there you
don't need.  It works just fine with an empty dhclient.conf.  (I'm using
the Debian dhcp-client package, which is the ISC's "dhclient" DHCP
client program.)

I reload my firewall rules if my IP address changes:

bj@morpheus:~$ cat /etc/dhclient-exit-hooks 
if [ -n "`ifconfig eth1 | grep UP`" ]; then
  if [ x$old_ip_address != x$new_ip_address ]; then
    /etc/init.d/firewall restart
    exit $?
  fi
fi 

Just run dhclient, pump, or whatever.  The defaults should work just
fine.
