The only odd netmask to memorize is the /23 netmask, which is 255.255.254.0. That is also not hard to remember because it is just one off from the .255 directly above it. Note that after the /23 network, all of the network masks are identical to the /25 - /30 networks, just move them over one octet to the left. Calculate all the subnet information you may need. It's fast, it's easy, it allows you to cut and paste and it accepts both CIDR (/24) and netmask notation (255.255.255.0). You may also want to learn how to subnet or check out the more advanced calculator which will allow you to plan a whole network out. That’s why we created this awesome looking IPv4 CIDR cheat sheet for you to use. Consideration: Download Solarwinds Free Advanced Subnet Calculator along with this cheat sheet to ensure you have all the IP information you need even when you’re offline. Feel free to print it out and hang it up or share a link to it with your colleagues and Enter your netmask(s) in CIDR notation (/25) or dotted decimals (255.255.255.0). Inverse netmasks are recognized. If you omit the netmask ipcalc uses the default netmask for the class of your network. Look at the space between the bits of the addresses: The bits before it are the network part of the address, the bits after it are the host part.

Maximum number of bits from 1st to 4th octet is Looking at the You will also need to factor in the 2 unusable IP addresses for network and broadcast addresses. However, from what we now know, this question is actually just asking you for the number of This clear this confusion, we use Network Classless Inter Domain Routing (CIDR) Cheat Sheet CIDR Cheat Sheet. Here is some explanation. Prefix is bit count for network address; Amount Of a Class C is how many C class network can be created in this network; Potential Hosts is the count of IP numbers; Actual Hosts is the count of usable IP numbers because 1 IP is used for network address and 1 IP is used for broadcast purposes.
