Term

Definition
| A type of address specified in IPv6 that represents a group of interfaces, any one which (and usually the first available of which) can accept a transmission. At this time, anycast address are not designed to be assigned to hosts, such as servers or workstations, but rather to routers |

Term
| APIPA (automatic private IP addressing) |
|
Definition
| A service available on computer running the windows 98, me, 2000, xp, vista, server 2003, or server 2008 operating system that automatically assigns the computer's network interface an IP address from the range of 169.254.0.0 to 169.254.255.255 if an IP address hasn't been assigned to that interface |

Term
| ARP (Address Resolution Protocal) |
|
Definition
| A core protocal in the TCP/IP suite that belongs in the network layer OSI model. ARP obtains the MAC (physical) address of a host or node, and then creates a local database that maps the mac address to the hosts IP logical address |
|
|
Term
|
Definition
| A database of records that maps MAC addresses to IP addresses. The ARP table is stored on a computers hard disk where it is used by the ARP utility to supply the MAC address of network nodes given their IP address |

Term
| DHCP (Dyanamic Host Configuration Protocol) |
|
Definition
| An application layer protocol in the TCP/IP suite that manages the dynamic distribution of IP addresses on a network. Using DHCP to assign IP addresses can nearly eliminate duplicate addressing problems |

Term
| DNS (Domain Name System or Domain Name Service) |
|
Definition
| A hierarchical way of tracking domain names and their addresses, devised in the mid–1980s. The DNS database does not rely on one file or even one server, but rather is distributed over several key computers across the internet to prevent catastrophic failure if one or a few computers go down. DNS is a TCP/IP service that belongs to the Application layer of the OSI model |
