-Find the valid subnets/hosts-Find the broadcast address-Find the valid hosts-Find the first valid host/last valid host However, I'm still not there yet. I'm still getting … Solved: 2. [subnetting: Class C] Given: Subnet a. How many subnets does the chosen subnet mask produce? b. How many valid hosts per subnet are available? c. What are the valid subnets (list IP addresses for the first three subnets (i.e.,the first, second, and third subnet)? d. List broadcast IP addresses for the first three subnets. e. List first and second host IP addresses for the second Router Security - Subnets and IP addresses IP addresses that start with 10 default to a different subnet scheme. Here, the subnet is defined simply by the first number. A subnet mask, of indicates this. Any IP address that starts with 10 would be valid (,,, etc). E is a valid address for the subnet "110" whcih is a valid subnet. I see this way: B and E are valid IP address and I think it's what they mean as "IPv4 addresses are vaild subnet addresses" although the question in the way it's put is likelly to cause misunderstanding.

The subnet calculator implements a classful / classed IP addressing scheme where the following rules are adhered to: Class A addresses have their first octet in the range 1 to 126 (binary address begins with 0).

May 26, 2020 · Total valid subnets are: Here “n” is number of 1’s in last octet. Valid hosts are: Here “n” is the number of zeros’ in last octet. Therefore, the number of valid subnets is “32”. The number of hosts per subnet can be created is “6”. Jul 15, 2020 · Subnets help reduce network congestion. A subnet is a widely-used practice in network management that involves breaking up a network into sections. Subnetting creates several interconnected networks under a single address space, viewing each section as a sub-network, or “subnet”, rather than a collection of independent networks.

ipv4 - Networking Question - What is a VALID Subnet

Oct 25, 2011 · John. Yes the 512th subnet is valid. Many people get confused about how this works. And part of the confusion is that they take the principle that you can not use the first and last address in the subnet and they apply it to subnets (can you use the first and last subnet).
