Alternative IP Representations

An IPv4 address can be expressed in several equivalent forms — dotted-decimal (127.0.0.1), 32-bit decimal (2130706433), hexadecimal (0x7F000001), octal (017700000001), or mixed-base. This tool converts any IPv4 between every common representation directly in your browser. Useful when testing WAF input filters that only block the dotted-decimal form, or when tracing IPs in obfuscated payloads from CTFs and bug-bounty reports.

Mixed-base forms (e.g. 0x7F.0.0.1 or 0177.0.0.1) are particularly effective at evading naïve regex-based blocklists because most filters check only the four-octet decimal pattern.

Converts an IPv4 address to alternative representations useful for security testing and WAF bypass.
