Confusing hex with dotted decimal
'C0.A8.00.01' is hex; '192.168.0.1' is decimal. Mixing them silently changes the IP.
Fix: Always label or prefix hex IPs explicitly (e.g. 0xC0A80001).

What is IP to Hex Converter
Written by Giorgos Kostas. Last reviewed:
IP to Hex Converter returns each octet of an IPv4 address as a zero-padded uppercase hexadecimal pair, separated by dots (e.g. C0.A8.00.01).
Hex IPs appear in packet dumps, embedded-device configs, debugger memory inspectors, and some firmware, where a byte-by-byte hex view is easier than decimal.
Why use it
- Match IPv4 addresses in packet captures and Wireshark hex exports.
- Read IPv4 fields from embedded device configs and firmware.
- Align C-style network code that treats the IP as a uint32_t.
- Cross-check IPv4 bytes against a memory dump.
- Produce compact identifiers (contiguous 8-character hex form).
Features
- Uppercase zero-padded hex pairs
- Dotted and contiguous forms both supported
- Matches Wireshark hex exports
- Runs fully in the browser
- Instant conversion as you type
How to use IP to Hex Converter
- Paste an IPv4. Enter an IPv4 address like 192.168.0.1.
- Read the hex form. The tool emits uppercase hex octets separated by dots.
- Copy it. Copy the hex IPv4 into your firmware config or packet comment.
Example (before/after)
IPv4 dotted-decimal
192.168.0.1
Hex octets
C0.A8.00.01
Common errors
Case sensitivity
Some parsers are case-sensitive and reject lowercase letters.
Fix: Use uppercase hex or convert with the Hex to IP tool which accepts both cases.
Expecting 0x prefix
Prepend 0x when feeding to C or Python parsers.
Fix: Add the 0x prefix if the consumer expects it.
FAQ
What format is used?
Zero-padded uppercase hex pairs separated by dots.
Can I get a contiguous 8-character hex?
Yes — drop the dots when copying. The Hex to IP tool accepts both forms.
Is it the same as the network byte order hex?
Yes. Octet 1 is the high-order byte.
Does it support IPv6?
No. Use an IPv6 tool for 128-bit addresses.
Does it run in the browser?
Yes.
How do I go back?
Use Hex to IP.
