Dotted Hex vs. Packed Hex
This tool shows two equivalent hex representations: dotted hex (C0.A8.01.01), which keeps each octet visually separated like dotted-decimal notation, and packed hex (0xC0A80101), which concatenates all four bytes into a single hex integer — the form more commonly seen in low-level system logs and legacy database columns.
Key Takeaways
- Bidirectional: Converts decimal to hex and hex back to decimal automatically.
- Two Hex Formats: Shows both dotted and packed hex representations for decimal-to-hex conversions.
- Client-Side Only: All conversion happens locally in your browser — no data is ever sent to a server.
