It looks fine, superficially, but all those fiddly 4-bit, 34-bit, and 30-bit values are going to be a real pain for implementation. I don't know if this is going to be implemented on servers that are not embedded in devices that can do location calculations, but if it is, it would be better to use a less complex numbering scheme. It's normally considered bad form to have a DHCP option that requires special modifications to the server in order to implement. I'm also a bit skeptical that DHCP is even the right way to do this, because the DHCP server's physical location, and even the relay agent's physical location, is not the same as the device's physical location. For wired devices, you can figure out the devices location through a database lookup, but for wireless devices you need to triangulate, and I have trouble figuring out how you're going to cram that functionality into a DHCP server. _______________________________________________ dhcwg mailing list dhcwg@ietf.org https://www1.ietf.org/mailman/listinfo/dhcwg
