How do i find my ip subnet mask

If you change any of these settings from their default values, Workstation does not update that setting automatically if the value is within the valid range.

If the value exceeds the valid range, Workstation resets the settings based on the subnet range. Workstation presumes that a custom setting should not be modified, even if you later change the setting back to its default value. Verify that you have administrative privileges on the host system. Log in to the host system as an Administrator user. Only an Administrator user can change network settings in the virtual network editor on a Windows host system.

Select the host-only or NAT network. The address should specify a valid network address that is suitable for use with the subnet mask. If your network is not subnetted, you must use the subnet mask associated with your IP address class. For example, if the Class A network ID is The default subnet mask is represented as Dustin Hannifin, A subnet mask is another group of dotted decimal numbers, representing a binary number that distinguishes which part of the IP address represents the network.

The subnet mask is used to allow computers to determine whether the addresses of other computers they wish to communicate with are on the local network or on a remote network. If the computer resides on a remote network, the communication request is sent to the default gateway. Figure 3.

How the Subnet Mask Works. The three main IP address classes have default subnet masks. The standard subnet masks for each class, including number of supported hosts on each network are listed in Table 3. The default subnet mask is not practical in most network configurations. For example, let us say that you owned a Class B network of Using the default mask, you could have over 16, computers on one nonroutable network segment.

Finding Network ID of a Subnet (using Subnet Mask)

What if you had a remote office connected via a WAN link? Would you need to acquire another Class B network range for that office?

First, this would be a major waste of your IP addresses and second, good luck on getting someone to give you that many. Luckily, you can create custom subnet masks to split up your IP addresses. By simply changing the subnet mask from Creating a custom subnet mask is as simple as adding some binary ones to replace zeros in the mask. But what if you need to support computers in a remote network? What does the mask look like then? This is where it gets a little tricky. You will need to convert the dotted decimal to its binary equivalent and perform a simple calculation.

Let us take a look at this process. Decide how many subnets or networks you need to support. This is pretty easy to calculate. Figure out how many networks you have that are separated by a router. Decide how many hosts you need on each network. You need to plan for the number of computers and other IP devices that you will want to support at each network location. Remember that you may need IP addresses for network switches, printers, and other IP-enabled devices on top of the number of computers that you need to support each network. You should plan for growth here as well.

Calculate the subnet mask. You now have enough information to calculate the proper custom subnet mask. Perform the following to calculate your subnet mask. Convert the standard subnet mask to binary. If we are using an IP network of The binary conversion is Notice that it takes eight binary numbers to make up the number between each decimal. This is why each number between the decimal is referred to as an octet. Add one to the number of networks subnets you need.

Assume that you need five networks.

Add one to it to get six. Convert the decimal number to binary. You can do this manually or the calculator in Windows works great for this. In our example, we convert the decimal number six to binary, which is Calculate the bits required for the mask. This is equal to the bits required to create the binary number. Since is three individual numbers, 3 bits are required. Add the bits to the standard subnet mask resulting in a new binary subnet mask of Now convert this binary back to decimal resulting in You now have the subnet mask to use on each network segment.

Now that you have learned how to create a custom subnet mask, you should be aware that you can use a special subnet calculator to perform these steps for you. However, it is important that you understand how subnetting works if you plan on supporting Windows networks. Anthony C. A subnet mask determines which parts of the IP address are network and host identifiers.

It is a bit number that distinguishes each octet in the IP address. For example, as depicted in Table 4. Table 4. IP Address Class Identifiers. Keeping in mind the unique class identifiers within the first byte of the IP address see Table 4. The first two octets of an IP address would identify the Class B network, the next octet would identify the subnet within that network, and the final byte would select an individual host.

Subnet masks are on a bit-by-bit basis; thus a subnet mask like Caputo, in Digital Video Surveillance and Security , This is a bit number that distinguishes each octet in the IP address. For example, as depicted in Table , Table Keeping in mind the unique class identifiers within the first byte of the IP address see Table , in a subnetted network the network portion can be extended to Dale Liu, The subnet mask is used in IPv4 and IPv6 to show what part of the address is the network portion and what part of the address is the host portion.

In IPv4 there are three default subnet masks corresponding to the three classes of IP addresses as illustrated earlier. There are currently three ways of showing the subnet masks for IPv4 addresses; you can show them in dotted decimal, binary, or classless interdomain routing CIDR. Dotted decimal is shown in Table 1. You could subnet this to make a few smaller networks as with the default mask you have 18,,,,,, possible addresses on one IPv6 network. Tables 1. These subnet mask tables can make it easier for you to determine which subnet mask to use for any given situation.

Look at the tables for just a minute and notice what happens. As you go down the table, the number of subnets increases and the number of hosts in each subnet then decreases. Look at the right-hand side of each table.
