Novel task for DNS.

[William Noad]

Greetings DNS Gurus,

I have what may sound like a strnage requirement, so I'll give you the
background first.

I work for ntl, a major UK ISP.  One of our future products will include
user accounts that can `expire', requiring the user to re-register (to
some degree) to reactivate the account.  We can (apparently) set up RADIUS
on the modem racks such that anyone whose account has expired gets put
into a specially constructed sandbox, from which they either re-register
or logout.  To ensure the user hits the re-registration system we want to
set up a DNS server within the sandbox that resolves /any/ domain name to
the IP address of the re-registration server.

I think that this should be possible using BIND configuration files, but
the timescales I have been given preclude (sadly) carrying out all the
research myself.

Has anyone else set up something similar using BIND? Or can someone
categorically say `that can't be done'.

Hope you can help.

TIA
	William Noad
