Modify jail IP without restarting

[Darryl Yeoh]

Hi guys,

I'm on FreeBSD 9-STABLE/amd64 at the moment and is there a way to
add/modify a jail's existing IP address without restarting jail ?

Initially the jail was configured with 5 IP addresses. And now we have
clients requesting additional IP addresses. A bunch of users
are in the jail at the moment and I don't want to restart the jail just
cause of this.

Thanks.
