### How do you find the subnet mask of an IP address?

255.248 or /29.
1. STEP 1: Convert to Binary.
2. STEP 2: Calculate the Subnet Address. To calculate the IP Address Subnet you need to perform a bit-wise AND operation (1+1=1, 1+0 or 0+1 =0, 0+0=0) on the host IP address and subnet mask.
3. STEP 3: Find Host Range.
4. STEP 4: Calculate the Total Number of Subnets and Hosts Per Subnet.

### How do you create a subnet?

Procedure
1. Click the Network tab.
2. In the Subnets tab, click Create.
3. In the Create Subnet dialog box, specify subnet details, such as the name, subnet IP address or subnet mask, range of IP addresses, gateway address, and broadcast domain.
4. Click Create.

### What is subnet in IP address?

A subnetwork or subnet is a logical subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting. Computers that belong to the same subnet are addressed with an identical most-significant bit-group in their IP addresses.

### What is Subnet Mask example?

You can determine the number and type of IP addresses any given local network requires based on its default subnet mask. An example of Class A IP address and subnet mask would be the Class A default submask of 255.0. 0.0 and an IP address of 10.20.

### What exactly is a subnet?

A subnet, or subnetwork, is a network inside a network. Subnets make networks more efficient. Through subnetting, network traffic can travel a shorter distance without passing through unnecessary routers to reach its destination.

### What is the purpose of a subnet?

Each computer, or host, on the internet has at least one IP address as a unique identifier. Organizations will use a subnet to subdivide large networks into smaller, more efficient subnetworks. One goal of a subnet is to split a large network into a grouping of smaller, interconnected networks to help minimize traffic.

### How do I find my subnet?

The number of subnets is found by counting the number of bits by which the initial mask was extended, also known as the subnet bits. Our initial address allocation was 192.168. 0.0 with a mask of 255.255. 0.0.

### Why is subnet mask used?

A subnet mask is used to divide an IP address into two parts. One part identifies the host (computer), the other part identifies the network to which it belongs. To better understand how IP addresses and subnet masks work, look at an IP address and see how it’s organized.

### How do you define subnet mask?

A subnet mask is a number that defines a range of IP addresses available within a network. A single subnet mask limits the number of valid IPs for a specific network. Multiple subnet masks can organize a single network into smaller networks (called subnetworks or subnets).

### What is custom subnet mask?

The custom subnet mask, also called a variable length subnet mask, is used to identify the bits used for a network address versus the bits used for a host address. ■ Custom subnet masks are used when subnetting or supernetting.

### What is difference between subnet and subnet mask?

Subnet – A portion of a network that shares a particular subnet address. Subnet mask – A 32-bit combination used to describe which portion of an address refers to the subnet and which part refers to the host.

### Where is subnet mask on router?

1. In the Windows search fields, type cmd, to open command prompt.
2. Press Enter.
3. Type ipconfig/all press Enter.

### What is a 16 subnet?

For example, /8 means 255.0. 0.0, /16 is 255.255. 0.0, and /24 is 255.255. 255.0.

### Can a subnet mask be anything?

A subnet mask hides, or “masks,” the network part of a system’s IP address and leaves only the host part as the machine identifier. A common subnet mask for a Class C IP address is 255.255. 255.0. The last section of each computer’s IP address can be anything from 0 to 255.

### What is a 255.255 254.0 subnet?

255.255.254.0 = 23 bits mask = 510 hosts (512 -2 ) 255.255.252.0 = 22 bits mask = 1022 hosts (1024 -2 ) 255.255.248.0 = 21 bits mask = 2046 hosts (2048 -2) You always multiply by 2 or divide by 2..and remove 2 hosts (broadcast and network)

### Is subnet mask always 255?

All subnet masks must end in 0, 128, 192, 224, 240, 248, 252, 254, or 255—the values of each bit position as they are “turned on” left to right in any octet.

### What does the mask 255.255 0.0 tell you?

A subnet mask is used to tell the network devices (whether it be the computer or any routers, modems, etc.) Likewise, if the subnet mask is 255.255. 0.0, then the computer will assume that every IP address in its local network will be in the format of 192.168.

### Is 255.255 255.255 IP address valid?

255.255 represents the local broadcast address, which is only propagated within the network. This broadcast data cannot cross routers by default. That is, it is a restricted broadcast address. For the local host, this address refers to all hosts in the network segment (same broadcast domain).
