IP to Hex Converter: Convert IPv4 and IPv6 Addresses
The IP to Hex converter turns an IPv4 or IPv6 address into hexadecimal you can copy into code, documentation, or another tool. IPv4 output includes a continuous 0x-prefixed value and a dotted-hex form such as C0.A8.00.01; IPv6 output is the full 32-digit hexadecimal value. Choose uppercase or lowercase letters and whether to show the 0x prefix.
The IP to Hex converter changes an IPv4 or IPv6 address into hexadecimal notation. It provides a quick way to convert an IP address online when you need a hexadecimal representation for code, documentation, or another tool. For IPv4, the output includes a 0x-prefixed value such as 0xC0A80001 and a dotted-hex form such as C0.A8.00.01. For IPv6, it outputs the full 32-digit hexadecimal value.
The conversion options let you choose uppercase or lowercase hexadecimal letters and whether to include the 0x prefix. Enter an IP address, adjust those settings as needed, then review and copy the result. The IPv4 examples show the address represented as a continuous hexadecimal value or as dotted groups; the IPv6 result is presented as a full hexadecimal value.
IP addresses are commonly written in IPv4 or IPv6 notation, while hexadecimal is another way to represent their values. Converting between these representations can help when a system or workflow expects hexadecimal, or when you need to check a hexadecimal value against an IP address. The tool focuses on converting an address to hex; My-DevTools also provides a separate reverse-conversion page for taking the content back to an IP address.
The conversion runs entirely in your browser: the input is processed on your device and is not sent to a server. Once the page has loaded, the tool works offline, so you can convert an address without an active connection. It is useful for developers and DevOps engineers who need to prepare, review, or share IP address values in hexadecimal form.
Step 1: Enter the IPv4 or IPv6 address you want to convert.
Step 2: Adjust the available options to choose uppercase or lowercase hexadecimal letters and whether to include the 0x prefix.
Step 3: Review the hexadecimal result; IPv4 output includes a continuous value and a dotted-hex form, while IPv6 output is a full 32-digit value.
Step 4: Copy the result and use it in your code, documentation, or another tool.
Use case: Move an IP address into a system that accepts hexadecimal rather than standard IP notation.
Use case: Check whether a hexadecimal value you received corresponds to the IP address you expected.
Use case: Prepare an IP address conversion for developer documentation, a ticket, or a commit message.
Use case: Sanity-check an address conversion before copying the hexadecimal value into code.
Use case: Compare the continuous and dotted-hex representations of an IPv4 address when reviewing address data.
Use case: Convert an IPv6 address to its full 32-digit hexadecimal form for a workflow that needs that representation.
