I'm sorry for not having setup a dynamic reverse zone so I don't know how it will work, but one thing the document above doesn't explain (or perhaps I am reading it poorly) is if the reverse zone does any checking on the name provided by the client via DHCP.
What I mean is, if I say `send fqdn.fqdn "www.ietf.org.";' in dhclient.conf, will the DHCP/DNS server put a PTR for the IP I receive that says www.ietf.org.? This solution to this is pretty obvious though, so perhaps it is implemented.
