IP addresses appear in logs, allowlists, firewall rules and diagnostics. CodeSwissKnife converts IP addresses between decimal, hexadecimal, binary and standard notation locally.

Why convert IP addresses locally?

Addresses can reveal internal networks and hosts. A local converter keeps diagnostic values out of web tools.

Compare multiple representations

Convert addresses into decimal, hexadecimal, binary and standard notation, including pasted addresses that include prefixes.

Use strict address parsing

Strict IPv4 and IPv6 parsing rejects ambiguous forms and emits RFC 5952-style IPv6 output for predictable results.
