Assignment of tenancy to devices

Across a network differently managed or owned devices may belong to shared or separate domains or tenancies. In the present invention a device (70) provides an identifier to a bootstrapping server (72). In one embodiment the bootstrap server then provides information to the device to enable it to register with a device server (74), with the tenancy being assigned with the device server information. In other embodiments the device server requests the device tenancy information from the bootstrap server when the device registers with the device server (fig. 7a, not shown) ; the bootstrap server sends tenancy information to the device server after receiving the device identifier and before the device registers with the device server (fig. 8a, not shown) ; or the bootstrap server sends the device identifier to the device server and requests the device server to obtain tenancy information for the device prior to registration (fig. 9a, not shown).
