RE: [dhcwg] Leasequery: should it be standardized?

Greetings,

You guys are clearly on to something here.

I have just re-read the 04 draft. It proposes a solution to a rather
specific problem. It would indeed make sense to generalize it into
a more broadly applicable query protocol.

Let's try bit more radical tack:

It would be useful to add a list-query capability, so that the
protocol could return lists of addresses, based on a flexible set of
search criteria.
E.g.: all assigned IP-s on subnet x. Also, the query could enumerate the
pieces of information e desired.(e.g. expiration time, client id...
whatever)

The currently specified 04 draft would be a functional subset of the
general purpose protocol.

BTW.. I am surprised to see that the messaging formats is
very much inspired by the DHCP/BOOTP message structure.

Since this would be a brand new protocol, I fail to see the need to
carry this baggage. Err.. why do we need to have the bootp header in
the messages?

I respectfully propose to lay out the protocol messages
in a compact manner, fitted to the need of the
query protocol itself.

For all intensive purposes, the protocol could even be TCP based,
similar to the failover protocol.

If there is sufficient interest, I will be glad to provide some
examples of "general purpose" query and response formats.
