Title: Local IP address in the DHCP range
Post by: judgej on January 18, 2008, 12:36:53 AM

Is there a reason why a local IP address (linked to a MAC address) cannot be allocated within the DHCP range? I mean, the system does not allow it, but is there a *technical* reason why not, rather than just a foible of whoever put the admin script together?

It can be handy, after a machine has been allocated a DHCP address, and other machines get to know where it is, to 'lock' that machine onto that address. I'll raise a FR if there is no technical reason.

I'll also raise the fact that MAC addresses must be entered with ':' separating each part. It would be nice to be able to copy and paste an address such as '000E08CD774E' or '00-0E-08-CD-77-4E' from a device admin screen, or DOS box, and not have to go to the trouble of changing it to '00:0E:08:CD:77:4E'.

Make them different NFR's

Being able to copy and paste different formats would be handy
Find the verification routine, and post it and it'll help
start at 'slocate hostentries.pm'

You can already force DHCP to allocate a specific IP to a device by entering the IP & the MAC address into the Hostnames and addresses panel. See the manual.

Yes, I know the manual says that, but I am talking about a limitation in what it does. If the admin screen says "you can't do that", then what the manual says is not so relevant.

Bug raised on the "inside DHCP range" error message:

http://bugs.contribs.org/show_bug.cgi?id=3775 (http://bugs.contribs.org/show_bug.cgi?id=3775)

Edited: I have my answer - there is no technical reason why it can't be done; just a policy decision by the developers, and that policy won't be changing.

The second FR:
