That's fine. So, now I can use that increment to find my network ranges. 150.5.0.0. We go .5.2.0 .5.4.0 .5.6.0 and down and down and down we go. Right? Now again, same trick as the last nugget. We don't want to take this through 1.0. We want to go 150.5.1.255. 150.5.3.255. Right? Last IP address before 4.0 and down and down we go. Now, interesting enough, you might be asked, well how many hosts per network does that really give you? Well, we look at our formula, we say, well that would be two to the power of nine because I've got nine host bits minus two, because we've got to account for the first and last IP address.
