How to Calculate Subnet Mask Values

What are the binary and decimal values of the new subnet mask? The correct binary and decimal values of the subnet mask are 11111111.11111111.11111111.11111111 in binary and 255.255.255.255 in decimal, respectively, which corresponds to option A) Binary: 11111111, Decimal: 255. Each sequence of 11111111 in binary translates to the decimal number 255.

If you're learning about network subnetting, understanding how to calculate the binary and decimal values of a subnet mask is crucial. In this scenario, we have a subnet mask of 11111111.11111111.11111111. These binary digits represent the subnet and host parts of an IP address.

The subnet mask can be converted into decimal format by translating each segment of 8 binary digits into its decimal equivalent. In this case, all 1s in binary equal 255 in decimal. Therefore, the subnet mask 11111111 in binary is equivalent to 255 in decimal.

When all four segments of the subnet mask are converted from binary to decimal, you get the complete subnet mask value of 255.255.255.255. This full subnet mask indicates that no bits are available for host assignment, making it a /32 subnet mask.

Understanding subnetting and subnet masks is essential for network administrators and anyone working with IP addresses. It allows for efficient use of IP address space and better network management. If you grasp the concept of subnet masks and how to calculate their values, you'll be better equipped to design and maintain robust network infrastructures.
