Binary / Hex Representation

Expand the Binary Representation (IPv4) or Binary / Hex Representation (IPv6) panel below the results to see the address in binary form.

IPv4

• Network row — 32-bit binary address; blue bits are the network portion (determined by the prefix length), grey bits are the host portion.
• Mask row — 32-bit binary subnet mask.
• Hex — network address as a 0-padded 8-character hex string (e.g. c0a80100 for 192.168.1.0).
• Decimal — network address as an unsigned 32-bit integer.
• The boundary line shows the split: Network: 24 bits | Host: 8 bits.

Click the Hex or Decimal values to copy them.

IPv6

• Address rows — 128-bit binary; blue = network bits (prefix), grey = interface bits.
• Hex rows — the address in full uncompressed hexadecimal.

Use cases

• Verify subnet boundaries when designing address plans.
• Convert between dotted-decimal, hex, and binary for ACL and firewall rule writing.
• Confirm the network/host boundary for VLSM allocations.
