Hex to IPv4 Converter
Convert an 8-digit hex value into a dotted IPv4 address — explicitly IPv4, as distinct from the 32-digit IPv6 address space.

How to Convert Hex to IPv4
An IPv4 address is a 32-bit number split into four 8-bit bytes (octets), written in decimal and separated by dots. Converting from hex means splitting the 8 hex digits into four 2-digit pairs — each pair is one byte — and converting each pair to decimal.
Where Hex to IPv4 Actually Comes Up
Reading an IPv4 Address From a Packet Capture
Raw packet dumps show source and destination IPv4 addresses as hex bytes — converting to dotted decimal makes them recognizable.
0x08080808 -> 8.8.8.8
Decoding a Firewall Rule's Hex-Stored Address
Some configuration formats store IPv4 addresses in hex for compactness — converting back to dotted decimal is often the first step in auditing a rule.
hex address field -> readable IPv4
Distinguishing IPv4 From an IPv6-Mapped Address
When working with dual-stack systems, explicitly converting the IPv4 portion confirms you're reading the correct 32-bit value rather than accidentally treating it as part of a longer IPv6 address.

Why Use This Calculator Instead of Doing It by Hand
- Handles the byte-splitting and hex-to-decimal conversion for all 4 octets at once
- Automatically pads shorter hex values to the full 4 bytes
- Runs entirely in your browser — nothing you type gets sent anywhere
- Catches invalid input (too many digits) instead of producing a wrong address silently
Limitations
- Reads the hex value as big-endian (most significant byte first) — use the Hex Little Endian IP Converter if the source stored it little-endian.
- Supports IPv4 only — see Hex to IPv6 for the 128-bit address space.
Frequently Asked Questions
Why does this page specify "IPv4" instead of just "IP"?
To be explicit that this handles the 32-bit IPv4 address space (8 hex digits), as distinct from IPv6's much larger 128-bit space (32 hex digits) — see Hex to IPv6 for that instead.
How do you convert hex to an IPv4 address?
Split the 8 hex digits into 4 byte pairs, then convert each pair to its decimal value — those four numbers, joined with dots in order, are the IPv4 address.
What if my hex value has fewer than 8 digits?
It's padded with leading zeros to 8 digits first — 0x7F becomes 0x0000007F, which converts to 0.0.0.127.
Does byte order matter?
Yes — this converter reads the hex value big-endian (most significant byte first). If the result looks reversed, try the Hex Little Endian IP Converter instead.
