Looks like you're using ipfw, in which case this works for me:
# /etc/rc.d/ipfw restart

In dhclient.conf, add your own DNS servers, plus your ISP's as backup:
Interface "xl0" {
prepend domain-name-servers xxx.xxx.xxx.xxx, yyy.yyy.yyy.yyy;
request subnet-mask, broadcast-address, routers, domain-name-servers;
}
Get new ip:
# dhclient xl0
Hope this helps
