IP Addressing

6to4 tunneling

A limited IPv4-to-IPv6 transition mechanism that allows for encapsulation of IPv6 packets in IPv4 packets transmitted over IPv4 networks is known as

DHCP (Dynamic Host Configuration Protocol)

A network protocol providing an alternative solution to the manual allocation of IP addresses is

APIPA (Automatic Private IP Addressing)

A service available on computers running one of the Windows operating systems that automatically assigns the computer's network interface a link-local IP address.

unicast

A type of network traffic intended for a single host identified by a unique IP address is referred to as

DHCP (Dynamic Host Configuration Protocol) issue

APIPA addresses are valid only for communications within a network segment that a given host is connected to. A host with APIPA-assigned address (i.e. an IP address in the range between 169.254.0.1 and 169.254.255.254) cannot connect to the Internet. The assignment of APIPA address typically indicates a problem related to

Teredo Tunneling

An IPv4-to-IPv6 transition mechanism with native support for Network Address Translation (NAT) is called

APIPA (Automatic Private IP Addressing)

An IPv6 link-local address is an equivalent of IPv4's

FE80::/10

32 bits

IPv4 address consists of how many bits?

240.0.0.0 - 255.255.255.254 (240.0.0.0/4)

IPv4 address range reserved for future use

127.0.0.0 - 127.255.255.255 (127.0.0.0/8)

IPv4 address range used for loopback addresses

decimal

IPv4 addresses are expressed with the use of

127.0.0.1

IPv4 loopback address

Class D (224-239)

IPv4 multicast address block

128 bits

IPv6 address consists of how many bits?

hexidecimal

IPv6 addresses are expressed with the use of

0:0:0:0:0:0:0:1 or ::1

IPv6 loopback addresses (2)

class A address space

In 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 to the

class C address space

In IPv4 addressing, the leading octet of an IP address with a value of 192 through 223 denotes that the IP address within that range belongs to the

Multicast

Messages are sent to a specific group of hosts on the network

Which of 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? QoS DHCP NAT DNS

NAT (Network Address Translation)

TRUE

T/F: A double colon in an IPv6 address indicates that part of the address containing only zeros has been compressed to make the address shorter

TRUE

T/F: An IP address that doesn't correspond to any actual physical network interface is called a virtual IP address (VIP/VIPA).

TRUE

T/F: Dynamic Host Configuration Protocol version 6 (DHCPv6) is the IPv6 equivalent of the Dynamic Host Configuration Protocol (DHCP) for IPv4.

TRUE

T/F: One of the 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

TRUE

T/F: The term "Dual-stack IP" refers to a solution that relies on implementing both IPv4 and IPv6 protocol stacks on various network devices to facilitate seamless migration from IPv4 to IPv6.

Broadcast

Used to communicate with all hosts on the network.

IPAM (IP Address Management)

a method for managing a network's IP address space

Anycast

a one-to-nearest (from the perspective of a router's routing table) flow.

NAT

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

EUI-64 (Extended Unique Identifier-64)

enables automatic configuration of an IPv6 address

VLSM (Variable Length Subnet Mask)

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

reservation

permanent IP address assignment from a DHCP server

static IP addresses

permanent assignment of an IP address

subnet mask

what determines which network segment an IP address belongs to

FE80:A7::2AA:0:4C00:FE9A (can get rid of leading zeros, keep following zeros, can only have double colons once in the address)

what is the valid address of FE80:00A7:0000:0000:02AA:0000:4C00:FE9A after compression?
