>When DHCP assigns an IP Address, it actually LEASES the identifier to the host computer or network device, for a specific amount of time. The default lease is five days, although a network administrator can evaluate their own particular circumstances to determine an appropriate lease (time).
In BASIC terms, the DHCP lease process works as follows:
1- A network device attempts to connect to the network.
2- The network requests an IP Address.
3- The DHCP server allocates (Leases) the network device, an IP Address, which is forwarded to the network by the Router.
4- DHCP updates the appropriate network servers with the IP address and other configuration information.
5-The network Device accepts the IP address.
6- * The IP address lease EXPIRES.
7- DHCP either reallocates the(same?) IP address or LEASES one that is available.
8- * The Network Device is NO Longer connected to the network.
9- The IP address becomes an available address in the network pool of Ip addresses.
NB: 1)- T o set up a DHCP, you basically need a DHCP supported client(at least one) and a Router, and a DHCP Server.
2)- DHCP is merely designed as an extension of the BOOTP functionality, and not as a replacement.
- BOOTP indirectly uses a form of leasing that Never Expire.
I hope this information can be of some help to the numerous 'connectivity' issues we face.
