What subnet mask would the 10.0.0.0\/24 network use? <\/p>\n\n\n\n

A. 255.0.0.0 <\/p>\n\n\n\n

B. 255.255.0.0 <\/p>\n\n\n\n

C. 255.255.255.0 <\/p>\n\n\n\n

D. 0.0.0.255<\/p>\n\n\n\n

The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The correct answer is C. 255.255.255.0<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

The notation 10.0.0.0\/24<\/strong> represents an IP network using CIDR (Classless Inter-Domain Routing) notation. The number after the slash (“\/24”) indicates the number of bits<\/strong> used for the network portion of the IP address. In this case, “\/24” means that the first 24 bits of the IP address are reserved for the network portion, and the remaining 8 bits are used for host addresses.<\/p>\n\n\n\n

To understand how this translates to a subnet mask, let’s break it down:<\/p>\n\n\n\n

    \n
  1. CIDR Notation<\/strong>: The “\/24” means 24 bits of the IP address are for the network. In binary, the subnet mask for a \/24 network would look like this: 11111111.11111111.11111111.00000000<\/code> Each group of 8 bits corresponds to one octet in the subnet mask. The “1” bits represent the network part of the address, and the “0” bits represent the host part.<\/li>\n\n\n\n
  2. Subnet Mask in Decimal<\/strong>: When converting the binary form to decimal, each octet of the subnet mask is converted individually:
    • 11111111 (binary) = 255 (decimal)<\/li>
    • 11111111 (binary) = 255 (decimal)<\/li>
    • 11111111 (binary) = 255 (decimal)<\/li>
    • 00000000 (binary) = 0 (decimal)<\/li><\/ul>So the subnet mask is 255.255.255.0.<\/li>\n\n\n\n
    • Why not other options?<\/strong>:\n
        \n
      • A. 255.0.0.0<\/strong> would be a \/8 network, meaning the first 8 bits are for the network, not 24.<\/li>\n\n\n\n
      • B. 255.255.0.0<\/strong> would be a \/16 network, meaning the first 16 bits are for the network, not 24.<\/li>\n\n\n\n
      • D. 0.0.0.255<\/strong> is not a valid subnet mask.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

        Thus, the correct subnet mask for the 10.0.0.0\/24 network is 255.255.255.0<\/strong>. This allows for 256 IP addresses in total (including the network and broadcast addresses), with 254 usable host addresses.<\/p>\n","protected":false},"excerpt":{"rendered":"
