Tip: /24 is the classic home network (254 usable hosts). /16 covers a large enterprise block, /30 fits a point-to-point link.

How to use

  • Enter an IP address in the four octet boxes (it starts at 192.168.1.10).
  • Drag the CIDR slider from /0 to /32 and watch every value recalculate in real time.
  • Copy any result with the 📋 button next to the network address, broadcast, mask, or wildcard.

3 pro tips

  • /24 is your home network — 254 usable hosts, the classic setup for home and small offices.
  • /30 fits a point-to-point link — exactly 2 usable addresses, perfect for router-to-router connections.
  • Read the binary rows under each result to see exactly which bits the mask covers — great practice if you're studying for a networking certification.

Keep this one bookmarked, my friend — the next time a device asks for a subnet mask, you'll have the answer in two seconds.
