Just to clarify,
The Redback holds a dynamic pool provided by the ISP from which it allocates IP's dynamically. However, it also caches the last IP that you were allocated and will reallocate this if it hasn't been taken by anyone else. This should never occur as the ISP's have to provide a pool of IP's that is bigger than the number of users they are connecting. Hence you should always get the same IP unless the Redback scrambles it's caching files or they get reset some other way.
This means that the IP you get is 'dynamic' and Telecom cannot guarantee that it won't change. ( 'dynamic' not 'static' but I think the difference is moot! ).

Anyone able to comment on how this might interact with DHCP or
_prevent_ fixed IPs which is what I though had been more or less
stated ?

Um, we get technical here (I may not have heard correctly), we went
through this on friday night, if I understood Mark Barlow correctly,
effectively we have static IPs as the redback holds the details in a
database, on a 'normal' fall over of the red back when it reboots we
regain our 'static' IPs from the database, its only on a serious crash that
the redback may have a corrupted database that is unusable so we
would get a new IP, effectively our dynamic IPs are static in all but name,
at least at present.

The reason we cannot get true static Ips at present is the redback is a
new company and their software/hardware is still young, later true static
may well be possible as the software matures and features are added.
Mark said he turns his adsl off at the help desk every night and always
regains his 'static' IP.

Hope Ive written accurately
