Hex to IP Converter

Paste a hex value — either the packed 8-digit form like C0A80001 or the dotted-hex form like C0.A8.00.01 — and get the standard dotted-decimal IPv4 address back.

What is the Hex to IP Converter?

The Hex to IP Converter reverses hex-encoded IPv4 addresses back into the familiar dotted-decimal form everyone recognizes. It accepts either an unbroken 8-digit hex string or four dot-separated hex groups, automatically detecting which format you've pasted.

How It Works

If the input contains no dots, it must be exactly 8 hex digits, which are split into four two-digit groups. If it does contain dots, each of the four groups is used directly. Every group is parsed as hex, checked that it falls within the 0-255 byte range, and joined with dots to build the final decimal address.

Real-World Use Case

When a piece of network hardware or a legacy log file shows an address as C0A80001 instead of a normal IP, converting it back to 192.168.0.1 makes it recognizable and searchable in the rest of your tools.

Frequently Asked Questions

Which hex formats does it accept?

Both the packed 8-digit form with no separators (C0A80001) and the dotted-hex form with a dot between each pair (C0.A8.00.01) — the converter detects which one you entered by checking for dots.

What if a hex group is out of range?

Since a hex group must represent a single byte, any group whose decimal value would exceed 255 is impossible for a valid IPv4 octet, so that entry is flagged as invalid.

Can lowercase hex letters be used?

Yes. Both uppercase and lowercase hex letters (a-f or A-F) are accepted and produce identical results.
