The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on UDP/IP networks whereby a DHCP server dynamically assigns an IP address and other network configuration parameters to each device/computer on a network.
- Static vs dynamic IP addressing
- Reservations
- Scopes
- Leases:
show ip dhcp binding - Options (DNS servers, suffixes)
- IP helper/DHCP relay
Available DHCP Servers:
- ISC-DHCP (DHCP) Configuration
- Cisco IOS dhcp server
- dhcpcd:
/etc/dhcpcd.conf
dhclient -r INTERFACE dhclient -r INTERFACE -v (verbose)
