510 is correct, just subtract 2 for network and broadcast addresses.

Wait, how do you get 510? I thought it was less.

I believe it's 510 usable IPs, but I could be wrong. I remember the formula but not the exact numbers!

Wait, is it 512 total addresses for a /23? I feel like I might be mixing up the calculations.

I practiced a similar question last week, and I think the answer was 510 because you take the total addresses and subtract 2.

I think I remember that in a subnet, you subtract 2 for the network and broadcast addresses, but I'm not sure how that applies to a 23-bit mask.
