You have four networks of 99.34.64.0, 99.34.68.0, 99.34.78.0 and 99.34.95.0 you need to supernet in order to use once ACL in a firewall.

99.34.64.0 – 99.34.95.0 fall into the range of 99.34.64.0 – 99.34.95.255 which consists of a 32 decimal division. The first octets are 255.255, to calculate the 3rd octet we need to covert 32 decimal to a binary bit mask: 2^5 = 32. As we are working on the subnet we work from the left. The …

What is the broadcast address for 145.50.23.1/22?

Classification 145.50.23.1/22 is a “Class A” IPv4 address. It is “classless” address as it does not use the default subnet for “Class A” addresses (255.0.0.0 or /8).
