IP Address Converter
Convert IPv4 addresses between dotted-decimal, integer, binary, hexadecimal, and octal representations. Expand and compress IPv6 addresses. Detect address class, private, loopback, link-local, and multicast ranges. Runs entirely in your browser — your data never leaves your machine.

All interactive tools run entirely in your browser. Your data never leaves your device.
How It Works
Enter an IPv4 address in any format (dotted-decimal, integer, hex, or binary) and see all equivalent representations instantly. Switch to IPv6 mode to expand compressed addresses or compress expanded ones. The tool also identifies address class and special ranges.
Features
- IPv4 multi-format input: accepts dotted-decimal (192.168.1.1), integer (3232235777), hex (0xc0a80101), or binary
- 7 output formats: dotted-decimal, integer, hex, binary, octal, IPv6-mapped, IPv6-compatible
- IPv6 expand/compress: expand
::1to full 8-group notation and compress back - IPv4-mapped IPv6: detects and extracts IPv4 from
::ffff:a.b.c.daddresses - Address classification: Class A/B/C/D/E detection
- Special range detection: private (RFC 1918), loopback, link-local, multicast
- Copy any value: one-click copy for each conversion result
- 8 examples: localhost, private, Google DNS, integer, hex, IPv6 loopback, mapped, Google IPv6
- Private: runs entirely in the browser — no data transmitted
Use Cases
- Converting IP addresses for firewall rules or configuration files
- Debugging network issues with different IP representations
- Converting between IPv4 dotted notation and integer for database storage
- Expanding compressed IPv6 addresses for inspection
- Identifying if an address is private, loopback, or multicast
- Complementing the IP Subnet Calculator with format conversion
