We know it can be pain trying to remember which CIDR notation to use or what subnet mask to enter for a specific subnet. That’s why we created this awesome looking IPv4 CIDR cheat sheet for you to use.
Feel free to print it out and hang it up or share a link to it with your colleagues and peers.
Consideration: Ditch the spreadsheets and subnet scanners and download Solarwind’s IP Control Bundle to keep tabs on your IP address space and who and what is on it. I particularly like the canned integration with AD DNS and DHCP which allows me to manage as well as report and alert on everything with an IP or hostname from a single location.
