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. and Cell (B) has the SubNet Mask of

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 - 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, / 20 /20 mean In which octet subnet mask is being changed? 3 rd octet Oct 22, 2019 · ip ip calculator ip subnet ipv4 subnet mask cheat sheet network subnet mask cheat sheet subnet mask cheat sheet class b subnet mask cheat sheet ipv6 Share this Story Previous Post Great solution for your social media accounts Next Post How To Add a User and Grant Root Privileges on Ubuntu 16.04 / 18.04

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.

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.
