## Questions

### Why does 127.0.0.1 become 2130706433?

The four octets are the bytes of one 32-bit number: 127×256³ + 0×256² + 0×256 + 1. That is why some sites accept the decimal form as the same address.

### Why would I need the integer form?

Firewalls, access rules and some APIs store addresses as integers because they are cheaper to compare and range-check than strings.
