An IPv6 to IPv4 transition protocol that provides automatic tunneling of IPv6 traffic over an IPv4 network. It can handle host to router or router to host tuennling, often used to create a router to router tunnel
number of addresses availalbe in an IP network number that can be assigned to hosts
An address type used in IPv6 to allow a one-to-many relationship between source and destination, the packet is delivered to only one of the possible destination computers
Automatic Private IP Addressing (APIPA)
A private range of IP addresses assigned to an APIPA enabled computer automatically when an IP address is requested via DHCP but no DHCP server responds to the request
The bounds of a network that defines which devices must receive a packets broadcast by an other device, usually an IP subnet
method of expressing an IP address in the format A.B.C.D/n where n is the number of 1 bits in the subnet mask or the number of bits in the network ID
use of IP addresses with their default subnet masks according to their address class A, B or C
Classless Interdomain Routing (CIDR)
A method of IP addressing in which the network and host IDs are determiend by a prefi number that specifies how many bits of the IP address are network bits, the remaining bits are host bits
format for expressing an IPv4 address, its four decimal numbers separated by periods
Dual IP layer architecture
Current architecture of IPv6 in Windows, both IPv4/6 share the other components of the stack
Extended unique identifier EUI 64 interface ID
An autoconfigured IPv6 address that uses the MAC address of the host plus an additional 16 bits
Intrasite Automatic Tunnell Addressing Protocol ISATAP
An automatic tunneling protocol used to transmit IPV6 packets between dual IP layer hosts across an IPv4 network
value used to express how many bits of an IP address are network ID bits. End of an IP address / #
32 bit dotted decimal address containing a network ID which specifies the network the computer is on, a host ID, which uniquely identifies the computer on that network
A reserved name that corresponds to the loopback address in an IP network
a binary operation in which there are two operands, the result is 0 or 1
an address that always refers to the local computer (IPv4 is 127.0.0.1 in IPv6 its ::1) used to test TCP/IP
value assigned to the gateway based on the speed of the interface used to access the gateway
AN address that identifies a group of computers running a multicast application
Network communication in whcih a packet is addressed so that more than one destination can receive it
A server with two or more NICs each attached to a different IP network. Each NIC is assigned a network connection and requires its own IP address
Network Address Translation (NAT)
A service that translates a private IP address to a public IP address in packets destined for the internet, then translates the public IP address in the reply to the private IP address. Often used to allow using private IP addresses while connected to the internet
an 8 bit value from 0-255 thats one of the four numbers in a dotted decimal address
Port Address Translation (PAT)
An extension of NAT that allows several hundred workstations to access the itnernet with a single public interent address by using Transport layer port numbers to differentiate each host conversation
A 32 bit dotted decimal number consisting of contiguous series of binary 1 digits followed by contiguous series of binary 0 digits taht determines which part of an IP address is a netowrk ID and host ID
Subdivisions of an IP network address space
Process that reallocates bits from an IP addresses host portion to the network portion, creating multiple smaller address spaces
Process that reallocates bits from an IP addresses host portion to the network portion, combining smaller sunets into a larger supernet
An automatic IPv6 over IPv4 tunneling protocol that solves the problem of 6to4 requirement of a public IPv4 address and the inability to traverse NAT routers
A common network protocol technique that allows transmitting a packet in a format that would otherwise be incompatible for the network architecture by encapsuating the packet in a compatible header format
an address in a unit of network data intended for a single destination device
