I've never had any company not be happy with that. If anything it is us insisting that their kit is not going on the main campus network!

We have been caught out by suppliers/vendors/integrators not supporting classless networking; therefore assuming everything is on a /24 netblock. We have therefore put together some procurement advice to make things like this a condition of the OJEU tender etc.
