Homework 5: Network Configuration

Hello,

Quick question about the Network configuration question in HW5 where we are supposed to allocate an IP prefix to each subnet:

The constraints state that the subnet must have enough addresses to support x interfaces. Should we assume the network address and broadcast address are included or not? ie consider x+2 interfaces?

Thank you,

Luka

I assume we have to, because interfaces D and E both have 2 network interfaces, yet 4 addresses. So let me change my question: Are there any scenarios where we don’t add 2 addresses- scenarios in terms of how the problem is stated?

Hi,

your assumption was correct: those addresses always exist and are necessary in any real network configuration. If you do not have to count those, it will probably be clearly stated in the exercice. In general, never forget those when allocating IP addresses.
