Subnet Va Subnet Mask
Subnet Vs Subnet Mask
Windows 7 manage wireless networks missing. The difference is very, very slight. 9 times out of 10, they will mean the exact same thing.However, the terms can have a contextual meaning in cases where we're discussing the subnetting of a given network. In those cases, the two terms 'network mask' and 'sub-network mask' can have distinct meanings. That is, if we make a distinction between a 'network' and a 'sub-network' then 'the mask of a network' and 'the mask of a sub-network' mean different things because of the context. This distinction is a relative distinction.For example, let's say you've been issued the 10.10.0.0/16 network (using ). Here, your 'network mask' is 255.255.0.0. Let's say you need to separate this network into 4 smaller networks, each as large as they could possibly be.
In order to get 4 networks out of 10.10.0.0/16, you need to borrow two bits (00, 01, 10, 11) from the host address and use them for the subnet addresses. This will give you the following sub-networks: 10.10.0.0/1810.10.64.0/1810.10.128.0/1810.10.192.0/18Here, your 'network mask' is still 255.255.0.0, but each 'subnet mask' is 255.255.192.0.But, as I said, it's completely a relative term based on context. One could also talk about 255.255.192.0 being a 'network mask' and then 255.255.0.0 being a 'supernet mask' if in the same context we're talking about 10.10.0.0/16 being a supernet of, say, 10.10.64.0/18. It's all based on the context of what is being discussed.
8 Steps to Understanding IP Subnetting. By Dale Janssen Step 4 - Subnetting and the Subnet Mask. To subnet a network is to create logical divisions of the network. Subnetting, therefore, involves dividing the network into smaller portions called subnets. Subnetting applies to IP addresses because this is done by borrowing bits from the host. Practice Problems based on Subnet Mask. Subnet Mask is a 32 bit number that identifies the subnet to which an IP Address belongs. How to calculate Subnet Mask? Subnet Mask for IP Address is calculated by setting all the bits reserved for network ID and subnet ID to 1 and all the bits reserved for Host ID to 0. It was all good while i am reading Classful IP and Subnetting in which host bits are borrowed to create further subnets until I chance upon the CIDR/VLSM topic. Over here, I saw this diagram below whereby a Class C IP (192.168.1.x) is having a subnet mask/CIDR of less then what a Class C network should be.
