Address Resolution Protocols
You should know the following protocols that perform address resolution.
|
Protocol |
Description |
|
Address Resolution Protocol (ARP) |
Used by hosts to discover the MAC address of a computer from its IP address. |
|
Reverse Address Resolution Protocol (RARP) |
Used by a host to discover the IP address of a computer from its MAC address. |
|
Bootstrap Protocol (BootP) |
Used by a host (such as a diskless workstation) to query a bootstrap computer and receive an IP address assignment. A BootP server has a static list of MAC addresses and their corresponding IP addresses. |
|
Dynamic Host Configuration Protocol (DHCP) |
An improvement on BootP, DHCP is used to dynamically assign IP address and other TCP/IP configuration parameters. A DHCP server can use a static list to assign a specific IP address to a specific host. More commonly, however, the DHCP server automatically assigns an IP addressfrom a preset range of possible addresses. |
