/** @module Interface wasi:sockets/ip-name-lookup@0.2.3 **/
/**
 * Resolve an internet host name to a list of IP addresses.
 * 
 * Unicode domain names are automatically converted to ASCII using IDNA encoding.
 * If the input is an IP address string, the address is parsed and returned
 * as-is without making any external requests.
 * 
 * See the wasi-socket proposal README.md for a comparison with getaddrinfo.
 * 
 * This function never blocks. It either immediately fails or immediately
 * returns successfully with a `resolve-address-stream` that can be used
 * to (asynchronously) fetch the results.
 * 
 * # Typical errors
 * - `invalid-argument`: `name` is a syntactically invalid domain name or IP address.
 *
