How does Subnetting Work?
I watched some videos about subnet masks and ip addresses, but I have a question that I couldnt find an answer for it, how to approach this question?
A PC’s IP-address inside a subnet is 22.214.171.124. Inside the subnet a maximum of 30 ‘legal’ (end)systems is allowed to be connected. What subnetmask (in dotted notation) is used?
That 30 makes it difficult to solve, If it was 32 then I would say 2^5 = 32 but since its 30 I have no idea how to solve
