Network Addressing

Question 1

Addressing

Answer 1

Identifier of a node or host on a network

Question 2

IP Address Types

Answer 2

IPv4 (32 bits) IPv6 (128 bits)

Question 3

MAC Address

Answer 3

MEdia Access Control ID assigned to device by manufacturer, hexadecimal format

Question 4

Gateway Address (default gateway)

Answer 4

Router interface that allows LAN data to be sent out of network

Question 5

Subnet Address

Answer 5

Dividing a network into two or more networks. Allows for efficient allocation of IP addresses if limited in large organizations

Question 6

Port Number

Answer 6

ip.ip.ip.ip:port for IPv4
[n:n:n:n:n:n:n:n]:n/ for IPv6

Question 7

IPv4 Structure

Answer 7

192.0.2.146
4 octets

Question 8

IPv6 Structure (::)

Answer 8

2001:0db8:85a3:0000:0000:8a2e:0370:7334.
Eight groups of four hexadecimal digits, each group representing 16 bits
:: used to shorten strings of 0s
2001:0db8:85a3:0000:0000:8a2e:0370:7334.
&raquo_space;>
2001:0db8:85a3::8a2e:0370:7334.

Question 9

MAC Address Structure

Answer 9

00:0a:45:2e:52:28
00-0a-45-2e-52-28
000.a45.2e5.228
6 octets
The first 24 bits (or three octets) are used as the Organization Unique Identifier (OUI), and 24 bits are vendor-specific and assigned to and burned into the NIC

Question 10

IPv6 Structure (/n)

Answer 10

N = bit size and ranges hexadecimal from 0-f
A network is denoted by the first address in the block (ending in all zeroes), a slash (/), and a decimal value equal to the size in bits of the prefix. For example, the network written as 2001:db8:1234::/48 starts at address 2001:db8:1234:0000:0000:0000:0000:0000 and ends at 2001:db8:1234:ffff:ffff:ffff:ffff:ffff.

Question 11

Subnet Address Structure

Answer 11

ip.ip.ip.ip/sub IPv4
limited from /16 - /32
