      In the 1990s, we were all taught that networks should be no larger than a /24 or what used to be called a Class C network. But a lot has changed since then. How big should your LAN be today?

        The timing on this might seem like I recorded it because of some other threads that were asking about this, but it just took a while to get posted. This was actually recorded a week or two ago.

          Hi,

          I always opt for /24 and if working with big company where 254 machines/servers/printers wont be suffice go with
          /16, however I never used /21 /22 or /23

          Perhaps i should have used them, but in a sense /16 worked and seems responsive enough, even though it is way bigger than the slots I need

            You should not use arbitrary CIDR sizes like that. As with everything, it should be designed to fit the business.

              It also makes it bigger than it is possible to use, encouraging problems and the bigger you make it, the more likely you are to experience problematic overlaps.

                I wish I could upvote this a few more times. At my last job, they were using a /11 network! That gives something like 2million IP addresses per subnet, I think. This was in 2004, with a colllege of 1,000 people at most. I couldn't even use tools like Spiceworks because they would balk when I told them I wanted to scan 2 million IP addresses, lol.

                We fixed that later, of course.
