The function call resolveIP requires 2 arguments.

Error message

The function call resolveIP requires 2 arguments.

What it means

Arity guard for resolveIP: the function takes exactly two arguments (hostname/IP and a flag where "IP" yields the hostname and anything else the address). Network failures themselves are swallowed and return "-"; only a wrong argument count throws.

Solutions

1. Call resolveIP(host, "IP") or resolveIP(host, "host") with exactly two arguments
2. Check the result for "-" to detect resolution failure
