Specs: Windows XP
i was going through Todd lamle and i found written as class B address.....though the address 172.16 stands for private B class address but /27 gives so please tell on what basis we should decide the class....

The concept of the Class of a network is only valid in a Classful Network. Once you start using subnet masks you are no longer dealing with a Classful Network, so the dichotemy doesn't really arise. A subnetted network doesn't have a Class.

That is a subnet of a class B address.
Always refer to it as a subnet of a class B address. As you have pointed out you should be able to tell instantly that it’s a class B either by putting the first octave into binary and the pattern starts with 10 or by knowing the private address ranges fall into to

But remember the subnet mask should not be used as an indicator of the class. also if you uses that adress with the subnet mask you will be told it is an illegal adress

all text needs typos. There there for the reader to find,to distract them from the total lack of content.
google it! wasnt the answer to the question i asked so dont be dense and give me that repl

Interesting ways of looking at it. You have to select a class that will support the number of nodes you need and to allow for growth. Call me silly but I always use Class A for for the private networks and Class B for DMZs. No logic behind this just that there is no costs to using Class A in a private network.

When it comes to WANs it is a different story entirely. You need to balance the number of networks you have with the number of host on that network. A lot of times you are given a small CIDR block to work with when building your WAN so it becomes very important. Also, if you are going to use Multicasting then you might need a different class entirely.

If I was building a new network from scratch I might just chose to go with IP v6 because you don't have to worry about classes and multicasting.

I am not sure if you are building a LAN or a WAN.
