In a Class B address, the first two octets are the network portion, so the Class B example in Figure 1 has a major network address of 128.0.0.0 - 191.255.255.255. Octets 3 and 4 (16 bits) are for local subnets and hosts. Class B addresses are used for networks that have between 256 and 65534 hosts.
Apr 06, 2020 Feed Detail - Cisco The numbers between the subnet numbers and the broadcast address. with a /25, you have 128 addresses per subnet, but .0 can't be used for a host, and neither can say .127. So the first subnet for 172.16.0.0 is: 172.16.0.0 - 172.16.0.127. But .0 can't be used because it's the "subnet number" and .127 can't be used because it's the broadcast. Subnetting Made Easy — TechExams Community The next subnet requires 14 hosts, we would use a /28 mask so 204.15.5.64 /28 = 204.15.5.64-204.15.5-79 the next subnet requires 7 hosts, so we would need to use a /28 mask again so we would start with the next IP 204.15.5.80 /28 = 204.15.5.80 - 204.15.5.95 the last subnet only requires 2 IP address so we would use a /30 mask the next IP address is

Class B addresses have their first octet in the range 128 to 191 (binary address begins with 10). Class C addresses have their first octet in the range 192 to 223 (binary address begins with 110). The subnet calculator allows the use of a single subnet bit - for example, a class C address with a subnet mask of 255.255.255.128 is permitted.
How To Subnet The IP address given was a class B address, making the first 16 subnet bits static. Using the cheat sheet, find the exponent of 2 that is equal to or greater than the number of subnets we require (900). We can quickly see that 10 additional subnet bits will give us 1,024 subnets.
