So it is "management want this broken behaviour" !

I don't think you'll be able to modify the server to do this, from 
what I gather the whole concept of addresses staying constant is 
built deep into the logic and it would require some very major 
changes to alter that.

Over here in the UK I see lots of stupid behaviour from ISPs - like 
charging silly premiums for fixed addresses. With ADSL the address 
pool is near enough required to be as big as your customer base 
because so many are now permanently connected with hardware routers 
and unlike dial-up you have to have a 'port' per user - it certainly 
does cost a third of the basic service extra to offer a fixed IP !
