An abandoned IPv4 address is an IPv4 address that was assigned by the DHCP server and marked as abandoned when either one of the following cases occur:
- The client sends a DHCP Discover to obtain a new lease but the IP address that the DHCP server is trying to offer already exists in the network. When the DHCP server receives a ping from the IP address, the DHCP server marks the IP address as abandoned.
- The client declines the IP address offered by the DHCP server by sending a DHCP Decline.
Abandoned IPv4 addresses appear as under Active IP Addresses. You can edit, move, and delete abandoned IPv4 addresses, and also change its state.
