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 Network Classless Inter Domain Routing (CIDR) Cheat Sheet Here we will learn how to calculate IP address, Network Address, Broadcast Address, Network Mask and provide these as cheat sheet.

Oct 22, 2019 How to Subnet Quickly and Avoid the Headaches | Udemy Blog Its subnet address is 192.168.16.32 and it broadcast address is 192.168.16.63, it is important to remember that a subnet always starts with an even number and the broadcast with an uneven number. The rules apply not just to Class C addresses but to the other classes as well, here is an example of a Class B borrowing bits in the third octet.
