Figure 8.12 DHCP server — list of leased and reserved IP addresses

• MAC Address — hardware address of the host that the IP address is assigned to (in-

cluding name of the network adapter manufacturer).

• Hostname — name of the host that the IP address is assigned to (only if the DHCP

client at this host sends it to the DHCP server)

• Status — status of the appropriate IP address; Leased (leased addresses), Expired (ad-

dresses with expired lease — the client has not asked for the lease to be extended

yet), Declined (the lease was declined by the client) or Released (the address has been

released by the client).

Note:

1. Data about expired and released addresses are kept by the DHCP server and can

be used later if the same client demands a lease. If free IP addresses are lacked,

these addresses can be leased to other clients.

2. Declined addresses are handled according to the settings in the Options tab (see

below).

The following columns are hidden by default (for details on showing and hiding columns, see

chapter

3.2):

• Last Request Time — date and time when the recent request for a lease or lease exten-

sion was sent by a client

• Lease Remaining Time — time remaining until the appropriate Lease Expiration

Use the Release button to release a selected IP address immediately (independently of its sta-

tus). Released addresses are considered free and can be assigned to other clients immediately.

Click on the Reserve button to reserve a selected (dynamically assigned) IP address based on
