An IPv4-to-IPv6 transition protocol that provides automatic tunneling of IPv6 traffic over an IPv4 network. It can handle host-to-router or router-to-host tunneling but is most often used to create a router-to-router tunnel. |
6to4 |
|
A method of automatic IP address assignment that occurs when a computer can't contact a DHCP server; uses the range 169.254.1.0 through 169.254.254.255. |
Automatic Private IP Addressing (APIPA) |
|
A packet addressed to all computers on the network. |
broadcast |
|
The bounds of a network that defines which devices must receive a packet that's broadcast by any other device; usually an IP subnet. |
broadcast domain |
|
A method of expressing an IP address in the format A.B.C.D/n; n is the number of 1 bits in the subnet mask or the number of bits in the network ID. |
CIDR notation aka Classless Interdomain Routing |
|
The use of IP addresses with their default subnet masks according to their address class: A, B, or C. |
classful addressing |
|
The use of IP addresses without requiring the default subnet mask. |
Classless Interdomain Routing (CIDR) |
|
The IP address of the computer a packet is sent to. |
destination IP address |
|
The current architecture of the IPv6 protocol in Windows, in which both IPv4 and IPv6 share the other components of the stack. |
dual IP layer architecture |
|
An auto-configured IPv6 host address that uses the MAC address of the host plus an additional 16 bits. |
Extended Unique Identifier (EUI)-64 interface ID |
|
An automatic tunneling protocol used to transmit IPv6 packets between dual IP layer hosts across an IPv4 network. |
Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) |
|
Similar in function to the IPv4 APIPA addresses, link-local IPv6 addresses begin with fe80, are self-configuring, and can't be routed. |
link-local IPv6 address |
|
A reserved name that corresponds to the loopback address, 127.0.0.1. |
localhost |
|
A binary operation in which there are two operands; the result is 0 if either operand is 0 and 1 if both operands are 1. |
logical and operation |
|
The IP address 127.0.0.1, which always refers to the local computer and is used to test the functioning of TCP/IP. |
loopback address |
|
A value assigned to the gateway based on the speed of the interface used to access the gateway. |
metric |
|
A network communication in which a packet is addressed so that more than one destination can receive it. |
multicasting |
|
A process that translates the source or destination IP address in a packet to a different value; often used to allow using private IP addresses while connected to the Internet. |
Network Address Translation (NAT) |
|
An 8-bit value; a number from 0 to 255 that's one of the four numbers in a dotted decimal IP address. |
octet |
|
The IP address of a computer that's sending a packet. |
source IP address |
|
A 32-bit dotted decimal number consisting of an unbroken series of binary 1 digits followed by an unbroken series of binary 0 digits. Used with an IP address to determine the network ID. |
subnet mask |
|
A process that reallocates bits from an IP address's host portion to the network portion, creating multiple smaller address spaces. |
subnetting |
|
A process that reallocates bits from an IP address's network portion to the host portion, effectively combining smaller subnets into a larger supernet. |
supernetting |
|
An automatic IPv6-over-IPv4 tunneling protocol that solves the problem of 6to4's requirement of a public IPv4 address and the inability to traverse NAT routers. |
Teredo |
|
A network protocol suite designed to deliver data packets to computers on any scale of network, from a small two-computer LAN to the worldwide Internet. |
Transmission Control Protocol/Internet Protocol (TCP/IP) |
|
A common network protocol technique that allows transmitting a packet in a format that would otherwise be incompatible for the network architecture by encapsulating the packet in a compatible header format. |
tunneling |
|
An address in a unit of network data intended for a single destination computer. |
unicast address |
|
An address for devices on a private network that can't be routed on the Internet. |
Unique local IPv6 address |
