IP to Binary online

How to Use the IP to Binary Converter

1. Enter an IPv4 address (e.g. 192.168.1.1).
2. All representations recompute as you type — no submit button needed.
3. Each octet is padded to 8 binary digits so subnet-mask alignment works.
4. Click Copy on any row to send that single representation to your clipboard.

Every IPv4 address is a 32-bit number; we just usually write it as four base-10 octets separated by dots because that is easier to memorise. This converter shows you the same address in all the other bases routers, libraries and packet captures actually use: per-octet binary (the form you need when sketching out a subnet mask), 0x-prefixed hex, colon-separated hex, the full 32-bit unsigned decimal, and per-octet octal.

How the IP to Binary Converter Works

Conversion is deterministic — there is no API call and no rounding. The binary representation always pads each octet to eight digits so that bit positions line up vertically with a CIDR mask, which is the whole point of looking at an address in binary. Validation is strict: anything outside 0–255 or missing a dot is rejected up front rather than producing a garbled output.

• Per-octet binary always padded to 8 digits for mask alignment
• Single 32-bit decimal output for SQL inet columns and INET_ATON-style storage
• Both 0xC0A80101 and C0:A8:01:01 hex forms in one click
• Strict 0–255 validation rejects malformed input rather than silently wrapping
