Question

How many valid ip addresses are possible in the given ip range (both ends included)? 192.168.56.12 - 192.168.57.256

Answer 1

Answer:

500 Valid IP addresses are possible

Explanation:

How many valid ip addresses are possible in the given ip range (both ends included)? 192.168.56.12 - 192.168.57.255

Correction 256 should be 255 as maximum 255 is possible

192.168.56.12  to 192.168.56.255

= 255 - 12 + 1

= 244

192.168.57.00  to 192.168.55.255

= 256

244 + 256 = 500

500 Valid IP addresses are possible

Answer 2

Answer:

There are 500 valid IP addresses that are possible in the given IP range, 192.168.56.12 - 192.168.57.256. From 192.168.57.256, 255 would be maximum and 12 should be subtracted from it and 1 added.

The result would be 244. Then 1 should be added to 192.168.57.256 with 255 as the answer. Then both the results, 256 and 244 should be added which results in 500.
