  5. Click Swap to reverse the conversion direction in one click.

Use cases

  • Study subnetting and binary arithmetic for networking exams (CCNA, CompTIA Network+).
  • Verify manual binary-to-decimal conversions for IP addresses.
  • Debug network configurations by checking binary representations of IPs.
  • Teach students how IPv4 addresses map to 32-bit binary strings.
  • Convert subnet masks (e.g. /24 = 11111111.11111111.11111111.00000000) visually.
  • Quickly confirm CIDR prefix boundaries in binary form.
