Hello Again all, I wonder if someone can advise if there is a simple way of getting the Mask Bits and Subnet ID. Say I have the following Info in the cells: Cell (A) has the IP addresses eg. 192.168.0.1 and Cell (B) has the SubNet Mask of 255.255.255.0.
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.

IPv6 is a complete and different animal as far as subnetting goes. Please note the yellow rows as each has special common use or notes. If there is nothing in the "Amount of a /64" column that means it is to miniscule or to massive to justify calculation. Not much is the same with IPv6 compared to IPv4. There is a quick cheat for class B and subnetting. Instead of checking the entire octet, check in which octet subnetting mask is being changed. Then do subnetting only for that particular octet. You will come up with the same result. Take a look, 172.35.0.0 / 20 /20 mean 255.255.240.0.

Mar 29, 2019 · Looking at the 171.44.0.0 block, you will discover it is a Class B address and Class B uses 16 bits to represent the network portion. Therefore, number of subnets will be: Note: Some questions around number of subnets used to be framed as follows : “How many subnets and hosts per subnet can you get from the network 172.25.0.0 255.255.255.192?”
Jul 15, 2020 · The subnet mask. The IP subnet mask will give you the Network ID for any given subnet. If you take the IP address of a device within the subnet and apply the subnet mask to it with Boolean algebra, you end up with the Network ID. Remember that the Network ID is also the first address in the range allocated to the subnet.

Each IP address class has a matching “subnet mask,” which is an easy way of identifying which part of the IP address relates to the network and which part relates to the host. This is essential to ensure packets traveling through the network get to the right place. The ISP was allocated a whole Class B range of 65,535 host IPs although they wanted only 4000. Thus, around 61,000 IP addresses were wasted. How CIDR is used. CIDR uses variable length subnet mask (VLSM) which is not based on the hard boundaries of the 3 Classes described above.
