A subnet mask is used for this purpose.
A subnet mask typically appears in the same format as an IP address, consisting of four octets separated by periods (e.g., 255.255.255.0). It identifies the network and host portions of an IP address, with the network part represented by consecutive ones (1s) in binary and the host part by zeros (0s). For example, in the subnet mask 255.255.255.0, the first three octets (255) indicate the network portion, while the last octet (0) indicates the host portion. Subnet masks can also be represented in CIDR notation, such as /24, which signifies that the first 24 bits are used for the network.
The subnet mask is used for this purpose. It indicates how much of the address is for network, and the remaining part is for the hosts.
The subnet mask helps determine which part of an IP address represents the network and which part represents the host. It is used by devices to identify whether an IP address is within the same network or needs to be routed to a different network. By using the subnet mask, devices can correctly send data to the intended destination within a network.
Subnet mask is a mask used to determine what subnet an IP address belongs to. Default gateway is the gateway in a network that a computer will use to access another network if a gateway is not specified for use.
Write the subnet mask in binary. The zeroes at the end represent the host bits, and therefore, the size of the network. If (for example) you have ten zeroes at the end, you rais 210 = 1024. That's the number of addresses in the network. Of these, the first and the last are reserved for special purposes, and can't be used for host addresses, so the complete calculation (in this case) is 210 - 2.Write the subnet mask in binary.

subnet mask
You can't find the gateway or any other address in a subnet mask; the subnet mask is used to separate the parts of an address - the network id part and the host id part. Look at other settings for the gateway, such as ipconfig or ifconfig
A service provider has given you the Class C network range 209.50.1.0. Your company must break the network into 20 separate subnets. Step 1) Determine the number of subnets and convert to binary - In this example, the binary representation of 20 = 00010100. Step 2) Reserve required bits in subnet mask and find incremental value - The binary value of 20 subnets tells us that we need at least 5 network bits to satisfy this requirement (since you cannot get the number 20 with any less than 5 bits -- 10100) - Our original subnet mask is 255.255.255.0 (Class C subnet) - The full binary representation of the subnet mask is as follows: 255.255.255.0 = 11111111.11111111.11111111.00000000 - We must "convert" 5 of the client bits (0) to network bits (1) in order to satisfy the requirements: New Mask = 11111111.11111111.11111111.11111000 - If we convert the mask back to decimal, we now have the subnet mask that will be used on all the new networks -- 255.255.255.248 - Our increment bit is the last possible network bit, converted back to a binary number: New Mask = 11111111.11111111.11111111.1111(1)000 -- bit with the parenthesis is your increment bit. If you convert this bit to a decimal number, it becomes the number "8‟ Step 3) Use increment to find network ranges - Start with your given network address and add your increment to the subnetted octet: 209.50.1.0 209.50.1.8 209.50.1.16 ...etc - You can now fill in your end ranges, which is the last possible IP address before you start the next range 209.50.1.0 -- 209.50.1.7 209.50.1.8 -- 209.50.1.15 209.50.1.16 -- 209.50.1.23 ...etc - You can then assign these ranges to your networks! Remember the first and last address from each range (network / broadcast IP) are unusable
This is easy to calculate due to the mask used. The network address would be 10.10.10.0 and the broadcast address would be 10.10.10.255.
That could be a default subnet mask for a class C network.A mask used to determine what subnet an IP address belongs to. An IP address has two components, the network address and the host address. For example, consider the IP address 150.215.017.009. Assuming this is part of a Class B network, the first two numbers (150.215) represent the Class B network address, and the second two numbers (017.009) identify a particular host on this network.Subnetting enables the network administrator to further divide the host part of the address into two or more subnets. In this case, a part of the host address is reserved to identify the particular subnet.
Subnetting divides a larger network into smaller, manageable sub-networks by borrowing bits from the host portion of an IP address to create additional network addresses. From a binary perspective, this involves manipulating the bits of the IP address to define the subnet mask, which specifies how many bits are used for the network versus the host. This process enhances routing efficiency, limits broadcast traffic, and allows for better utilization of IP addresses within a given network. Ultimately, subnetting helps in organizing and securing network architecture.
