Lesson Four - MTA Exam 98-366
Term | Definition |
---|---|
anycast address | A method of communications where a set of packets are sent to the first or closest computer within a set of computers. |
APIPA | Short for Automatic Private IP Address, it is a private range of addresses automatically assigned by a host that cannot connect to a DHCP server. |
broadcast address | An address that send messages to all hosts within a network. |
classful network architecture | A IPv4 classification system that uses classes to define characteristics of the assigned network. |
classless inter-domain routing (CIDR) | A way of allocating IP addresses and routing Internet Protocol packets. It was intended to replace the prior classful IP addressing architecture in an attempt to slow the exhaustion of IPv4 addresses. |
default gateway | The first IP address of the device that a client computer will look for when attempting to gain access outside the local network. |
DNS server address | The address of a DNS server, which is used to resolve host names to IP addresses. |
dual IP stack | The term used to describe when two Internet Protocol Software implementations in an operating system run, such as IPv4 and IPv6. |
dynamic IP address | An IP address that is automatically assigned to a host by a DHCP server. |
global routing prefix | The first three groups of numbers used in an IPv6 address. |
IP conflict | A conflict that occurs when two hosts are assigned the same address on a network. |
IPv4 | The most frequently used communications protocol. |
IPv4-mapped addresses | An IPv6 address where the first 80 bits are set to 0 and the last 32 bits contain an IPv4 address. |
IPv6 | An updated IP protocol that increases the address space and adds additional functionality compared to IPv4. |
IPv6 subnet | An individual subnet of the network that the address is located on. |
IPv6 tunneling | A method where IPv6 packets are encapsulated inside IPv4 packets. |
logical IP address | A address that is assigned to a host by the administrator. |
loopback IP address | A address used for testing of the host itself. |
masked | A mechanism used to isolate binary digit 1. |
multicast address | A type of communications where a single set of packets is sent to a single computer. |
multicasting | One set of packets sent to multiple computers. |
network address translation (NAT) | The process of modifying an IP address while it is in transit across a router, computer, or similar device.I.E. Private to Public. |
node | Another term for host, which is a computer or device that connects to the network. |
private IP addresses | Addresses from the Internet and any other network. |
public IP addresses | Addresses that are exposed to the Internet. |
static IP address | An address that is manually assigned to a host. |
Subnetting | The act of dividing a network into smaller logical subnetworks. |
TCP/IP | An popular protocol suite used on the Internet. |
Truncated | A method that abbreviates an IPv6 address by removing unnecessary and/or leading 0s. |
unicast address | communication method that sends a set of packets to a single host. |
unmasked | A mechanism used to isolate binary digits 0. |
