Dynamic Host Configuration Protocol (DHCP)

Flashcards covering key concepts and terms related to DHCP from lecture notes.

DHCP

Dynamic Host Configuration Protocol, a method for assigning IP addresses to computers on a network.

RFC 1531

The initial definition of DHCP published in October 1993.

Lease Period

DHCPv6

The extension of DHCP for Internet Protocol version 6 (IPv6) networks.

Advantages of DHCP

Includes minimizing administrative burden and preventing IP address conflicts.

Disadvantages of DHCP

Includes potential unavailability of the DHCP server and machine name not changing with IP address changes.

Security Issues with DHCP

DHCP is an unauthenticated protocol, allowing unauthorized users to request multiple leases and cause denial-of-service attacks.

DHCP Server

A server that automatically assigns IP addresses and other configuration information to clients on the network.

TCP/IP Operations

The suite of communications protocols used for the internet and similar networks, needed for DHCP to function.

Manual Configuration

The process of assigning IP addresses and settings to devices on the network without DHCP.
