Hex IP Converter
Convert an IPv4 or IPv6 address between dotted notation and hexadecimal.
About Hex IP Converter
An IPv4 address's 32 bits can be represented in hexadecimal, either as one 8-digit hex number (e.g. 192.168.1.10 → 0xC0A8010A) or as four 2-digit hex octets separated by dots (C0.A8.01.0A). Hex representations appear in packet captures, DHCP client identifiers, and some legacy Windows/Unix network tools. This converter works in both directions.
Formula
Decimal octet to hex
Each decimal octet (0–255) maps to a 2-digit hex value (00–FF)
- octet
- One 0–255 segment of the address
Worked example
With the default values below, Hex IP Converter returns Hex (32-bit) of 0xC0A8010A. Change any input above and every figure here is recalculated in your browser.

Frequently Asked Questions
Where are hex IP addresses used?
Hex notation for IPs shows up in packet analyzers like Wireshark, in Windows Registry entries for network adapters, in some router/firewall logs, and when working directly with raw socket or memory-level network data.
What is 192.168.1.10 in hex?
192.168.1.10 converts to 0xC0A8010A as a single 32-bit hex value, or C0.A8.01.0A per-octet.
Can I convert hex back to a decimal IP?
Yes — switch the conversion direction to 'Hex → Decimal IP' and enter the 8-digit hex value (with or without the 0x prefix).
