IPv4 Explorer is a simple, clean, web-based IPv4 address calculator. The tool currently reports the following for valid IPv4 addresses:
If the input address is a valid source adress, the following information is reported.
- dotted binary representations for all addresses
- network (routing prefix) bits are highlighted
- Network address
- Broadcast address
- first and last usable addresses
- IANA special registry information is reported by searching IANA’s special registry data for a supernet that contains the input address.
- Although the tool was not designed to handle multicast addresses, they are recognized. Reference links are currently reported for such cases.

- IPv4 Explorer makes use of Beau Gunderson’s ip-address library for some address handling.
