Answer to Question #279111 in Computer Networks for aayushi

Question

Given an IP address, network mask, and subnetwork mask, determine other information and implement it about the IP address such as:

      i.           The subnet address of this subnet.

   ii.           The broadcast address of this subnet.

 iii.           The range of host addresses for this subnet.

 iv.           The maximum number of subnets for this subnet mask.

   v.           The number of hosts for each subnet.

 vi.           The number of subnet bits.

vii.           The number of this subnet.

Answer 1

i.

Subnet addressing allows an autonomous system made up of multiple networks to share the same Internet address

ii.

The broadcast address of this subnet is the last address in the subnet

iii.

first address of subnet is network address, last address is broadcast address, all other are host addresses

iv.

To calculate the number of possible subnets, use the formula 2ⁿ, where n equals the number of host bits borrowed.

v.

 The number of hosts for each subnet:

$2^n-2$

where n is number of hosts bits

vi.

Subnet masks, like the IP address itself, are 32 bits in length. Subnet masks are composed of some number of 1 bits followed by enough 0 bits to form a 32-bit value, where the bit positions with a 1 correspond subnet address

vii.

number of subnet binary expression in IP address that corresponds to positions of 1s in subnet mask
