IP Address Converter — IPv4 / IPv6
Convert an IPv4 or IPv6 address: decimal, hex, binary, compressed/expanded IPv6, mapped forms.
Developer notes
• IPv4: dotted, uint32, hex, binary octets. • IPv6: compress / expand / both. • Mapped optional. • 64 KiB limit.
Options
When teams pick this route
• Compare compressed vs expanded IPv6. • Get the integer form of an IPv4 for a text ACL.

Local address forms
When should I use the number-base converter instead?
To convert an integer between bases 2–36 (hex of a number, binary of a value), use number-base-converter. Networking tools compute subnets and CIDRs — not general base conversion.
Are IP addresses uploaded?
No. All math runs locally in your browser. Nothing is uploaded to FastMinify.
What is the size limit?
64 KiB (UTF-8) for the combined input fields of each tool.
