DHCP - Dynamic Host Configuration Protocol
DHCP - System of assigniing IP addresses to each network device (host)or organisation network.
Central server that manges a pool of IP addresses and leases them out to requesting devices eliminating manual configurations
It improves network security as it reduces IP addresses conflicts by managing address allocation centrally. The configuration information includes the following:
- IP address
- Subnet masks
- Default gateway
- DNS Address
DHCP handshake

Lease time - the time a device can use the assigned IP
IP address pool - A range of IP address managed by the DHCP to distribute to devices
DHCP relay agent - Forwards DHCP messages between different networks.
