IPv4 Address Converter

IPv4 Address Converter is part of Toolspire and is ready as soon as this page loads. 192.168.0.1 is the integer 3,232,235,521, the hex value 0xc0a80001, and the binary groups 11000000.10101000.00000000.00000001.

What you can do here

Three spellings in, dotted decimal out

The headline is always the four octets. Integer, hex and binary sit in the detail so you can check each one.

Binary stays in four groups

Each octet is eight bits, padded. 192 is 11000000, not a single 32-bit string with no dots.

No mask applied

The address is not reduced to a network address. /24 belongs on the subnet or overlap page.

The sequence

How to use the IPv4 Address Converter

  1. 1

    Paste one spelling

    Use 192.168.0.1, or 3232235521, or 0xc0a80001. Do not include a prefix length.

  2. 2

    Check the integer against the hex

    The hex is the same 32-bit number. 0xc0 is 192, 0xa8 is 168, 0x00 is 0, 0x01 is 1.

  3. 3

    Leave subnet questions on the other page

    If you need the network or the broadcast, open the subnet calculator. This page will not guess a mask.

Worth knowing

  • IPv4 Address Converter on Toolspire: the integer is octet1 × 256³ + octet2 × 256² + octet3 × 256 + octet4.
  • 192.168.0.1 is 3,232,235,521, hex 0xc0a80001, binary 11000000.10101000.00000000.00000001.
  • You can paste the dotted form, the decimal integer, or 0x plus hex. All three name the same 32-bit value.
  • An octet above 255 is rejected. This page does not apply a subnet mask. The subnet calculator is the page for network and broadcast.

One 32-bit number, four ways of writing it

An IPv4 address is an unsigned 32-bit integer that people print as four decimal bytes. Hex is the same integer with a 0x prefix, eight digits so leading zeros stay visible. Binary is those four bytes in bits, because that is how a mask lines up in a textbook. 192.168.0.1 is the running example: 3,232,235,521, 0xc0a80001, and 11000000.10101000.00000000.00000001. The converter stops there. It does not decide whether the address is private, and it does not find a subnet.
