  1. Hmm, I always just issue “service networking restart” (or /etc/init.d/networking restart).

    Guess that isn’t the right way to do it, but works for me.

  2. @Jerad: I guess it depends on why you need a new lease. If you change networks you will get a new address by restarting networking, but that also brings me to the next question.

    @UbuntuGeek: Does dhclient -r release the lease and ask for a new address and get a fresh one, or will one get the same address you had earlier (if any)?
