IP to Integer / Integer to IP

Two functions for converting between IPv4 addresses and their 32-bit unsigned integer representation.

ip_to_int

Converts an IPv4 address string to a UBIGINT (unsigned 64-bit integer, but the value will always fit in 32 bits). Returns NULL for invalid or IPv6 input.

int_to_ip

Converts a UBIGINT integer back to an IPv4 dotted-quad string. Returns NULL if the value exceeds the IPv4 range (> 4294967295).

Roundtrip

The two functions are inverses of each other:

Use Cases

Sort IPs numerically instead of lexicographically:
