Question

The enterprise administrator has assigned Arthur the network address 172.16.85.0/25 for the branch office network that he is constructing. Arthur calculates that this gives him 126 (27) IP addresses, which is enough for his network, but he has determined that he needs six subnets with at least 10 hosts on each one. How can Arthur subnet the address he has been given to satisfy his needs? What IP addresses and subnet masks will the computers on his branch office network use?

Answer 1

To satisfy Arthur needs Arthur can subnet the address he has been given by using three host bits to give him eight subnets with up to 16 hosts on each one. The computers on his branch office network will use IP address ranges as 192.16.85.1 - 192.16.85.14 and a subnet mask of 255.255.255.240.

Step-by-step explanation:

IP address:

An Internet Protocol address (IP address) is a label in numerical terms which is assigned to each device that is connected to a network and uses protocols of Internet for communication.

Sub-net Mask:

A Subnet mask is a number of 32-bits that masks an IP address, and divides the IP address into network address and host address. Subnet Mask is made by setting network bits to all "1"s and setting host bits to all "0"s
