AppleTalk File Protocol (AFP)
A type of protocol that works in the upper layers of the OSI model to provide app to app interaction.
A special range of addresses that starts with 169.254 and is used by a computer when no DHCP server responds to a DHCP request.
Automatic Private IP Addressing (APIPA)
An IP addressing method in which address classes no longer dictate the part of an IP address designated as the network portion. A network admin can assign however many bits are appropriate to teh network design.

Internet Control Message Protocol (ICMP)
TCP/IP's primary network protocol; it provides addressing and routing information.
An updated version of IPv4 created to solve some problems inherent in that protocol, such as a somewhat limiting 32-bit address space, lack of built-in security, a sometimes complicated setup, and a lack of built-in Quality of Service.
