1: Develop an IP Addressing Scheme

You have been assigned an IPv4 network in the table below. You will subnet it to provide IP addresses to two subnets that will support the required number of hosts. All work must be shown using the IP Addressing worksheet below.

Network	Number of Hosts in Subnet A	Number of Hosts in Subnet B
172.16.1.0/25	60	20

IP Addressing Worksheet (Use this to show your calculations)

Specification	Subnet A	Subnet B
Number of bits in the subnet
IP mask (binary)
New IP mask (decimal)
Maximum number of usable subnets obtained from 172.16.1.0/25
Number of usable hosts per subnet
IP Subnet
First IP Host address
Last IP Host address

Record your subnet assignment in the table below.

Assign the first IPv4 address of each subnet to a router interface

subnet A is hosted on R1 G0/0/1

subnet B is hosted on R1 G0/0/0

Assign the last IPv4 address of each subnet to the PC NIC

Assign the second IPv4 address of subnet A to S1

List the maximum number of useable hosts per subnet

Description	Subnet A	Subnet B
First IP address
Last IP address
Maximum number of hosts

Record the IP address information for each device:

Device	IP address	Subnet Mask	Gateway
PC-A
R1-G0/0/0
R1-G0/0/1
S1
PC-B
