Dynamic Host Control Protocol (DHCP)

Address allocation can happen trough 2 ways.

Fixed allocation:

• Wasteful because if a hosts is not active the IP Address is still allocated.

Dynamic allocation:

• A DHCP server manages the allocation of IP Addresses and leases them for a certain amount of time.

Dynamic allocation works like this:

1. A host broadcasts a request for an IP Address.
2. A DHCP server replies with a offer for an IP Address.
3. The host replies accepting the offer.
4. Server confirms the allocation of the IP Address.
