Are the following IP adresses – 220.127.116.11 & 18.104.22.168 – used for broadcast, if they belong to B Class? (The adresses were randomly chosen). I suppose 22.214.171.124 would rather be a broadcast adress, but I’m not sure. Thanks in advance!
A class B network in CIDR notation is a /16 network. A broadcast address is where all of the host bits are 1. In your case, the last 16 bits would need to be 1 to be a broadcast address.
126.96.36.199 and 188.8.131.52 each have a zero bit in the last 16 bits, so they are not broadcast addresses.
If your class B is subnetted into /24’s, then the 184.108.40.206 address may be a broadcast address if 220.127.116.11/24 is the network address.
