Add DB API support for lookup against IP address fields

[kirk.reeves@…]

please add an additional key word for querysets when searching with the inet datatype..

and example would be
assume a table constructed as follows.

create table network_interfaces(
id serial,
ip inet,
interface char(20)
)

--The SQL Syntax ---
SELECT * from network_interface where ip << '10.210.0.0/16';

--possible Django syntax ---
Interfaces.objects.filter(ip_within='10.210.0.0/16')

Thanks. Django is a great project.

This is a nice idea (I'd think that overloading the "in" lookup type would work best) here, but I'm concerned that there's not a way to do this in a database-agnostic manner. Kirk, do you think you could do a quick survey of databases and see if it's going to be possible to do this generically?

Not a feature worth holding up queryset-refactor for. It can be done after the merge back into trunk. Removing the keyword.

This is solved by adding the ability for custom (per-field) lookup types to the ORM syntax. Adding specific new lookup types is going to generally deferred until somebody implements that.

Ticket for allowing custom lookup types is #14263.
