Which subnet mask will logically place the devices with IP addresses 10.10.5.5 and 10.10.10.10 on the same network?

Which subnet mask will logically place the devices with IP addresses 10.10.5.5 and 10.10.10.10 on the same network?

• A. 255.255.255.0
• B. 255.255.255.255
• C. 255.255.0.0
• D. 255.0.0.0

Answer: (C)

To determine which subnet mask allows the devices with IP addresses 10.10.5.5 and 10.10.10.10 to be on the same network, we need to look at how subnetting works with these addresses. The two IP addresses, 10.10.5.5 and 10.10.10.10, share a common prefix in their first two octets (10.10). The third octet is where they differ (5 and 10 respectively). A subnet mask of 255.255.0.0 means that the first two octets (10.10) will be the network portion, while the remaining two octets (the last two octets) will be available for host addresses. With this subnet mask, the entire range of IP addresses from 10.10.0.0 to 10.10.255.255 will belong to the same network. Since both 10.10.5.5 and 10.10.10.10 fall within this range, they can communicate directly on the same network. In contrast, the other subnet masks would not allow these two addresses to be on the same network: - A subnet mask of 255.255
