Artica Meta allows you to visualize DHCP leases in real time, enabling you to identify which IP addresses have been assigned to client devices by your DHCP server.
¶ The Status leases tab in the DHCP management panel
The status give 3 colors:
- Green: active - Lease is currently held by the client
- Grey: expired- Lease was active but has since lapsed or client released the lease or it expired naturally
- Red : abandoned - Client sent
DHCPDECLINE— IP was in use on the network when offered.
Server will not re-offer this IP until the abandon lease time elapses or it is manually cleared
What "abandoned" means ?
When a DHCP client receives an offer, it ARPs the proposed IP before accepting it.
If it gets a response (meaning another device already uses that IP), it sends a DHCPDECLINE back to the server.
The server marks the lease abandoned to avoid offering a conflicting address again.Common causes:
- A device has that IP statically configured
- A stale ARP entry made the client think the IP was taken
- A previous DHCP server left a ghost lease behind
