Guide to Subnet Mask (Subnetting) & IP Subnet Calculator

The 32-bit IP address contains information about the host and its network. It is very necessary to distinguish both. For this, routers use Subnet Mask, which is as long as the size of the network address in the IP address. Subnet Mask is also 32 bits long. If the IP address in binary is ANDed with its Subnet Mask, the result yields the Network Doing so enables the interfaces and allows communication with hosts on those interfaces using IP. Associated with this task are decisions about subnetting and masking the IP addresses. For information on IP addressing and subnetting, refer to these documents: IP Addressing and Subnetting for New Users; Configuring IP Addressing In any network, Internet Protocol (IP) addressing is needed to ensure that data is sent to the correct recipient or device. Both IPv4 and IPv6 address schemes are managed by the Internet Assigned Numbers Authority (IANA). Most of the internet that we know today is based on the IPv4 addressing scheme and is still the predominant method of Subnetting is a topic that can confuse a lot of people, so for the sake of this book subnetting will only be explained as the way to configure networks in the best way to save IP addresses. This is done by applying a mask that will filter out some of the computer’s IP address allowing the networks addressing to be uncovered.

PDF IP Addressing and Subnetting for New Users - cisco.com Understand Subnetting Subnetting allows you to create multiple logical networks that exist within a single Class A, B, or C network. If you do not subnet, you are only able to use one network from your Class A, B, or C network, which is unrealistic.

Class B IP addresses, like 128.16.7.4, use the first two bytes (128.16) as the network address, and the last two bytes (.7.4) as the host address. In a Class C address, like 204.176.22.1, the network portion of the address takes up three bytes (204.176.22), leaving only a single byte for the host portion (.1).
