//! Run with: `cargo run --example bulk`
//!
//! Bulk lookup is available on the Business and Unlimited plans only.
//! The library uses the GET / comma-separated form of the bulk endpoint:
//!
//!     https://ipwhois.pro/bulk/IP1,IP2,IP3?key=...
//!
//! Up to 100 IP addresses can be passed in a single call. Each address
//! counts as one credit.
