NET1L - Lesson 11 (IP Subnetting & VLSM Pt. 2)

Process of dividing our network into different subnets.

• IP Subnetting

• Subnet Masking

• Network Segmentation

Why is IPv4 Subnetting important?

For us to preserve the depletion or exhaustion of IPv4 Addresses (since we only have a total of _________ addresses).

• 4.3 billion

• 4.4 billion

• 4.3 million

• 4.2 million

Is a unique identifier for a node or host connection on an IP network.

• IP Address

• Subnet Mask

• Default Gateway

• Burn-in Address

An IPv4 address is a 32 bit binary number usually represented as ____________, each representing ______, in the range 0 to 255 (known as octets) separated by decimal points.

• 4 decimal values

• 8 bits

• 8 decimal values

• 16 bits

Example: 140.179.220.200

It is sometimes useful to view the values in their binary form.

This is known as "__________" notation.

• dotted decimal

• dotted number

• dotted binary

Every IP address consists of three parts, one identifying the network and one identifying the node.

• True

• False

The ___________ and the _________ determine which part belongs to the network address and which part belongs to the node address.

• Class of the address

• subnet mask

• default gateway

• Burn-in address

There are ___ different address classes.

• 4

• 5

• 6

Class A range:

• 1-126

• 1-127

• 128-191

• 240-254

Class B range:

• 1-126

• 1-127

• 128-191

• 240-254
