IconVault's IPv4 Converter turns any dotted-decimal IPv4 address into every common numeric form: the 32-bit unsigned integer, hexadecimal, binary, octal, and the IPv6-mapped (::ffff:) representation. Type an address and all conversions update instantly, with one-click copy on each value.

It validates each octet as you type and flags invalid input instead of guessing. It is free, needs no signup, and runs fully in your browser. Honest note: it converts the address you enter; it does not look up geolocation, ownership or whether the address is reachable.
