Question:
What is the broadcast address of the first subnetwork in a class-C network assigned with an IP address - 207.35.7.0 (The subnet mask is 255.255.255.248)
Answer:
To determine the broadcast address of the first subnetwork in the given class-C network with the IP address 207.35.7.0 and subnet mask 255.255.255.248, we need to follow a few steps.
The given IP address is 207.35.7.0, which is a class-C IP address. In a class-C network, the first three octets (207.35.7) represent the network portion, and the last octet (0) represents the host portion. The subnet mask 255.255.255.248 indicates that the first 29 bits (or 3 octets) are used for the network portion, and the remaining 3 bits (or 5 host bits) are used for the host portion.
The subnet mask 255.255.255.248 provides 5 host bits, which means there are 2^5 = 32 possible host addresses in each subnetwork. However, we need to reserve two addresses: one for the network address and one for the broadcast address. Therefore, each subnetwork can accommodate 32 - 2 = 30 hosts.
Since we are looking for the broadcast address of the first subnetwork, we need to find the subnetwork address first. To do this, we set all the host bits to 0 in the given IP address. Thus, the subnetwork address for the first subnetwork is 207.35.7.0.
To calculate the broadcast address, we need to set all the host bits to 1 in the subnetwork address. In this case, the host bits are the last 3 bits of the last octet. Therefore, the broadcast address for the first subnetwork is obtained by setting the last 3 bits of the last octet to 1.
207.35.7.0 (Subnetwork address)
207.35.7.7 (Broadcast address)
The correct answer is option 'D', 207.35.7.7.
What is the broadcast address of the first subnetwork in a class-C network assigned with an IP address - 207.35.7.0 (The subnet mask is 255.255.255.248)
Answer:
To determine the broadcast address of the first subnetwork in the given class-C network with the IP address 207.35.7.0 and subnet mask 255.255.255.248, we need to follow a few steps.
Step 1: Understanding the IP address and subnet mask
The given IP address is 207.35.7.0, which is a class-C IP address. In a class-C network, the first three octets (207.35.7) represent the network portion, and the last octet (0) represents the host portion. The subnet mask 255.255.255.248 indicates that the first 29 bits (or 3 octets) are used for the network portion, and the remaining 3 bits (or 5 host bits) are used for the host portion.
Step 2: Calculating the number of subnetworks
The subnet mask 255.255.255.248 provides 5 host bits, which means there are 2^5 = 32 possible host addresses in each subnetwork. However, we need to reserve two addresses: one for the network address and one for the broadcast address. Therefore, each subnetwork can accommodate 32 - 2 = 30 hosts.
Step 3: Determining the subnetwork address
Since we are looking for the broadcast address of the first subnetwork, we need to find the subnetwork address first. To do this, we set all the host bits to 0 in the given IP address. Thus, the subnetwork address for the first subnetwork is 207.35.7.0.
Step 4: Calculating the broadcast address
To calculate the broadcast address, we need to set all the host bits to 1 in the subnetwork address. In this case, the host bits are the last 3 bits of the last octet. Therefore, the broadcast address for the first subnetwork is obtained by setting the last 3 bits of the last octet to 1.
207.35.7.0 (Subnetwork address)
207.35.7.7 (Broadcast address)
The correct answer is option 'D', 207.35.7.7.
