Answer given is b i.e . 256 But my answer is 248 because total host = number of subnet * host per subnet = 4 * ( $2^{6}$ -2) = 4 * 62 = 248. If number of IP’S are asked then answer will be 256(I think). Somebody please verify.

Given answer (FROM PW) 4th = 5 5th = c I don’t understand 4th question properly. For the 5th I am getting c and d as answer. Explanation. Since 2 bit is used for subnet mask: then total 4 subnet possible: 1 = 152.158.0.0 to 152.158.63.255 2 = 152.158.64.0 to 152.158.127.255 3 = 152.158.128.0 to 152.158.191.255 4 = 152.158.192.0 to 152.158.255.255 Let me know where I am wrong.
