all my hosts have been on GREEN so far. Today I started to split them between BLUE and GREEN and assigning fixed IP adresses.
- Change connection from GN to BL and reboot host.
- Fetch MAC-address via DHCP
- Assign fixed DHCP lease and reboot host.
Here is the behavior that startles me: Many of devices show up in both, fixed and dynamic leases. Some of them show up twice under dynamic lease, the first time without MAC address. See example of one device highlightd in the screenshot below. They can be pinged via their latest dynamically assigned address.
Setup: ipfire 152 with APU4D2. BLUE and GREEN are both wired networks via unmanaged switches connected. Since the wiki page on DHCP states as expected:
All clients not listed in this section will be given an address from the ‘dynamic’ range set above.
What would be a reasonable explanation?
What should be my next course of action?
Restart ipfire, too? That does not seem the way it is supposed to work.
