Subnetting

Question 1

What is a host/host Id?

Answer 1

So a host is any device on the IP network.
A host Id is an IP address to uniquely Identify a single device in said network.

Question 2

What is a subnet mask?

Answer 2

A subnet mask is 32 charater IP, that shows what part of the IP is reserved for the network ans what part is reserved for hosts:

each 8 bit section is 1 for the network, and 0 for the host. for example

192.168.0.1 subnet mask is:

11111111.11111111.11111111.00000000

Mean the first three octates are reserved for the network and the last is researed for host

In CIDR notation the subnet mask is represented by the number of bits reserved for the network e.g /24, /8, /32, etc

Question 3

What are some rules to keep in mind when creating a subnetting table?

Answer 3

• The first network id is always the orginal id
• To get the next network Id you increase the last octate by the number of host for that specific type of subnett from the sunny table
• All the subnets share the same subnet mask
• All the subnets share the same number of host

Question 4

What is a broadcast id?

Answer 4

It is the las host Id in a subnet

Question 5

How do you calculate valid hosts id’s in a subnet and why?

Answer 5

Total number of hosts ids - 2

This is because the first host Id is reserved for the network and the las one is reserved for the broadcast address.

Question 6

Create the subnetting table as provided by sunny

Answer 6

This is the correct table order:
* Subnets,
* Hosts,
* Subnet Mask

Question 7

What aret the ranges of IP arressees?

Answer 7

Class A addresses start from 1 to 126 in the first octet; 127 is reserved for loopback.

Class B starts from 128 to 191.

Class C from 192 to 223.

Class D is multicast.

Class E is reserved.
