[Semibug] sshd configuration for Jails questions

Question.  I am configuring a server , the ip address comes from DHCP but I
want to run jails, which means restricting the IP Addresses sshd listens on.

Normally, this is done by IP but I don't know how to do it for DHCP.  Will
using the hostname work.  for example
ListenAddress hostname.mydomain.com

Or will that not work?

I have seen online that some people have cron scripts that look for a
change of DHCP IP and then update the sshd_config file and restart sshd but
I am hoping to avoid that...
Of course, I can use a non-standard port but not sure I want that either


P.S. Michael Lucas appears to not have addressed this in his book about
Jails  ;-)
