Class Notes
DHCP stands for Dynamic Host Configuration Protocol
DHCP is a Server Service
Separate from DNS
Can be found in Windows Servers/ Linux/ Unix and Home or Small office Routers
DHCP Servers Assign:
Dynamic IP Addresses
Static Subnet Mask
Static Default gateway
Static Primary and Secondary DNS Servers
Scope is the pool of addresses that the DHCP server can assign from. Such as192.168.1.100 to 192.168.1.200
Lease is the length of time that the DHCP server will reserve the IP address for the client.
Clients will try to renew the lease periodically
Lease length can be manually configured on a per server basis
Reservations are IP Addresses that are reserved for systems that need Static IP Addresses
Steps for Getting an IP
DHCPDiscover -- Client Requests an IP from Any Available DHCP Server
DHCPOffer -- DHCP Servers offer IP Addresses
DHCPRequest -- Client Acknowledges which IP Address it has accepted
DHCPAck -- DHCP Server Acknowledges Client has accepted IP Address
