Quiz IP addressing

There are 32 bits in an IPv4 address.

How many bits are in an IPv4 address? 256 32 64 128

128

How many bits are used for an IPv6 address? 32 256 64 128

Correct! 8 There are 8 bits in each octet (byte).

How many bits per octet in an IPv4 address? 6 8 2 4

14

How many hosts can you have with a subnet of 192.168.1.0/28? 14 16 6 30

4

How many octets are in an IPv4 address? 6 8 4 2

16

How many subnets do you get with a subnet of 192.168.1.0/28? 12 20 13 16

EUI-64

IPv6 can use a DHCPv6 server for the allocation of IPv6 addressing to hosts. Another IPv6 addressing option utilizes the IPv6 Neighbor Discovery Protocol (NDP) to discover the first portion of the IPv6 address (network prefix) from local routers, and the host can create its own host ID. What standard is commonly used by an IPv6 host to generate its own 64-bit host ID? 6to4 Teredo DORA EUI-64

Router Solicitation, Router Advertisement

IPv6 enables hosts to generate their own IPv6 addresses without the need for a DHCPv6 server. This is referred to as stateless address autoconfiguration (SLAAC) and utilizes the Neighbor Discovery Protocol (NDP) that is built into the IPv6 protocol. What are the some of the packet types associated with the NDP process? IPCP configure-request, IPCP configure-ack Router Solicitation, Router Advertisement DHCPDiscover, DHCPOffer Down, init, two-way, exstart, exchange

B

The IP address range of 172.16.0.0 - 172.31.255.255 is what address class? C A D B

Correct! Section A is the network portion, and Section B is the host portion. Subnet masks are used to separate the network and host portions of an IPv4 address. In a subnet mask, 1s are used to indicate the network portion of the address, and 0s are used to indicate the host portion of the address. In the preceding example, Section A is the network portion of the IPv4 address, and Section B is the host portion of the IPv4 address, due to the mask that is in use.

What are sections A and B of the IP address? Section A equals 8 bits, and Section B equals 0 bits. Section A is the network portion, and Section B is the host portion. Section A are used bits, and Section B are unused bits. Section A equals 255, and Section B are all 0s.

Tunneling Dual stack

What are two IPv6 transition technologies that can coexist with IPv4 to help ensure a smooth transition from IPv4 to IPv6? Anycast Tunneling Dual stack EUI-64

EUI-64

What format can be used to represent the low order 64 bits of an IPv6 address by reformatting a devices MAC address? IEEE 802.3ar IEEE 802.3ab EUI-48 EUI-64

169.254.0.0/16

What is the network address for APIPA? 10.0.0.0/8 169.254.0.0/16 172.16.0.0/16 192.168.0.0/24

VLSM

What practice allows you to further subnet a network as best as possible regarding the number of devices that need to be accommodated in each network? Classful addressing DDN Native VLAN VLSM

Double colon

What symbol can be used to represent a group of consecutive 0s in an IPv6 address? Period Double semicolon Semicolon Double colon

DHCP

Which IP addresses assignment method leads to less administrative efforts for Information Technology professionals? Statically Manually DHCP BOOTP

Broadcast

Which data flow is NOT supported by IPv6? Anycast Multicast Unicast Broadcast

2001::35d0:0:56:abed:e930:0001

Which option is NOT a valid representation of the 2001:0000:35d0:0000:5600:abed:e930:0001 address? 2001:0:35d0:0:5600:abed:e930:1 2001:0000:35d0::5600:abed:e930:0001 2001::35d0:0:5600:abed:e930:1 2001::35d0:0:56:abed:e930:0001

/29

You have a subnet mask of 255.255.255.248. What is the prefix notation? /27 /29 /26 /28

255.255.255.224

You have an IP address with a prefix notation of /27. What is the dotted-decimal form of the subnet mask? 255.255.255.128 255.255.255.224 255.255.255.192 255.255.255.0
