IP ADDRESSING QUIZ

IPv6

-128 bits -Expressed in hexadecimal -Loopback address: 0:0:0:0:0:0:0:1 or ::1

IPv4

-32 bits -Expressed in Deciamal Numbers -Loopback address: 127.0.0.1 -Multicast address block: 224-239, Class D

APIPA

-Automatic Private IP Address -This is a private range of addresses automatically assigned by a host that cannot connect to a DHCP server. -An IPv6 link local address is an equivalent of IPv4

IPAM

-IP Address Management -a method for managing a network's IP address space

NAT

-Name Address Translation -the solutions listed below hides the internal IP addresses by modifying IP address information in IP packet headers while in transit across a traffic routing device -solutions alleviates the problem of the depleting IPv4 address space by allowing multiple hosts on the same private LAN to share a single public IP address

VLSM

-Variable Length Subnet Masking -the name of a solution that increases the efficiency of IP address space management by allowing network administrators to divide networks into subnets of different sizes

DHCP

-network protocol providing an alternative solution to the manual allocation of IP addresses -A features of the Dynamic Host Configuration Protocol (DHCP) is the capability for static allocation of an IP address based on the IP-to-MAC address mapping

IPv4 addressing

-the leading octet of an IP address with a value of 1 through 126 denotes that the IP address within that range belongs___Class A -126 - 192 ___Class B -192 - 223___Class C

IPv4 loopback address range

127.0.0.0 - 127.255.255.255 (127.0.0.0/8)

IPv4 address range for future use

240.0.0.0 - 255.255.255.254 (240.0.0.0/4)

Miredo

A third-party software that provides Teredo service on UNIX and Linux systems.

4to6

A tunneling protocol that enables transmission of IPv4 packets over an IPv6 network.

Teredo

A tunneling protocol, named after the Teredo worm, that enables transmission of IPv6 packets over IPv4 networks. IPv6 addresses intended to be used by this protocol begin with the prefix 2001::/32. -An IPv4-to-IPv6 transition mechanism with native support for Network Address Translation (NAT)

VIP/VIPA

An IP address that doesn't correspond to any actual physical network interface is called a virtual IP address

link-local address

An IP address that is automatically assigned by an operating system to allow a node to communicate over its local subnet if a routable IP address is not available. ICANN has established the range of 169.254.0.0 through 169.254.254.255 as potential link-local IPv4 addresses. IPv6 link-local addresses begin with the prefix FE80::/10.

Class A, Non-routable (private) IP address range

The 10.0.0.0 - 10.255.255.255 (10.0.0.0/8) IPv4 address space

Class B, Non-routable (private) IP address range

The 172.16.0.0 - 172.31.255.255 (172.16.0.0/12) IPv4 address space

Class C, Non-routable (private) IP address range

The characteristic features of the 192.168.0.0 - 192.168.255.255 (192.0.0.0/24) IPv4 address space

6to4

The most common tunneling protocol that enables travel of IPv6 packets over IPv4 networks. IPv6 addresses intended to be used by this protocol always begin with the prefix 2002::/16.

Dual Stack IP

a solution that relies on implementing both IPv4 and IPv6 protocol stacks on various network devices to facilitate seamless migration from IPv4 to IPv6

Subnet mask

allows to determine which network segment an IP address belongs to

EUI-64

enables automatic configuration of an IPv6 address

Reservation

refers to permanent IP address assignment from a DHCP server
