How is an IPv4 address converted to binary?

Each of the four octets (0–255) is written as an 8-bit binary number, so the whole address becomes 32 bits. For example 192 is 11000000.

What is the decimal integer shown?

It is the address treated as a single 32-bit unsigned number, computed as octet1×16777216 + octet2×65536 + octet3×256 + octet4. This is how IPs are stored internally.

How is the hexadecimal form derived?

Each octet is written as two hex digits (00–FF), so the four octets become an 8-character hex string. For example 192.168.1.10 is C0.A8.01.0A, or 0xC0A8010A as a single value.

Why convert an IP to binary?

Binary makes subnetting and masking intuitive — you can see exactly which bits a subnet mask covers and which are host bits. It is also how routers and firewalls actually compare addresses.

What is the largest 32-bit IP integer?

255.255.255.255 equals 4,294,967,295 (2^32 − 1), the maximum unsigned 32-bit value. 0.0.0.0 is 0, so every IPv4 address maps to an integer in that range.

Is my IP address sent anywhere?

No. The conversion is pure arithmetic done in your browser — nothing is uploaded or logged.

IPv4 to binary, hex and decimal

Enter any IPv4 address and see it as binary (per octet and as one 32-bit string), hexadecimal, and the decimal 32-bit integer that the address represents internally. This is useful for studying subnetting, debugging firewall rules, and understanding how masks line up bit by bit.

How it works

An IPv4 address is four octets, each 0–255. The converter writes each octet as an 8-bit binary number and concatenates them into a 32-bit string, also showing the two-digit hex form per octet. The single decimal integer is computed as:

octet1 × 16,777,216 + octet2 × 65,536 + octet3 × 256 + octet4

(that is, octet1 × 2²⁴ + octet2 × 2¹⁶ + octet3 × 2⁸ + octet4).

Example

For 192.168.1.10:

Format	Value
Per octet binary	11000000.10101000.00000001.00001010
32-bit binary	11000000101010000000000100001010
Hexadecimal	C0A8010A
Decimal integer	3,232,235,786

Everything runs in your browser; nothing is uploaded.
