Question

tegan works for an isp and has been asked to set up the ip addressing scheme for a new region of the city they are providing with internet service. she is provided the class b address of 141.27.0.0/16 as a starting point and needs at least 25 subnets. what is the custom subnet mask for this, how many networks does this allow for, and how many hosts will be available on each subnet

Answer 1

1. The custom subnet mask in dotted-decimal notation is equal to 255.255.0.0.
2. The custom subnet mask would allow for four (4) subnets.
3. There are 16 host bits available on each subnet.

What is a custom subnet mask?

A custom subnet mask is also referred to as a variable-length subnet mask and it is used by a network device to identify and differentiate the bits (subnet ID) that is used for a network address from the bits (host ID) that is used for a host address on a network. Thus, it is typically used when subnetting or supernetting on a network.

Given the following data:

• Class B address = 141.27.0.0/16

• Number of subnets = 25.

Since the IP address is Class B, there are 16 bits for the subnet ID (141.27) while 16 are for the host ID. Thus, the custom subnet mask in dotted-decimal notation is equal to 255.255.0.0.

2. The custom subnet mask would allow for four (4) subnets.

3. There are 16 host bits available on each subnet.
