Frequently asked questions
Why convert an IP to an integer?
A 32-bit integer is a compact way to store, compare and range-check IP addresses — useful in databases, GeoIP lookups and firewall logic.
What does the binary form show?
It shows each of the four octets as eight bits, which makes subnet masks and network boundaries easy to see at a glance.
