Array with one AddressInfo per socket address.
SocketOSException on failure, or SocketFeatureException if this functionality is not available on the current system.
// Roundtrip DNS resolution auto results = getAddressInfo("www.digitalmars.com"); assert(results[0].address.toHostNameString() == "digitalmars.com"); // Canonical name results = getAddressInfo("www.digitalmars.com", AddressInfoFlags.CANONNAME); assert(results[0].canonicalName == "digitalmars.com"); // IPv6 resolution results = getAddressInfo("ipv6.google.com"); assert(results[0].family == AddressFamily.INET6); // Multihomed resolution results = getAddressInfo("google.com"); assert(results.length > 1); // Parsing IPv4 results = getAddressInfo("127.0.0.1", AddressInfoFlags.NUMERICHOST); assert(results.length && results[0].family == AddressFamily.INET); // Parsing IPv6 results = getAddressInfo("::1", AddressInfoFlags.NUMERICHOST); assert(results.length && results[0].family == AddressFamily.INET6);
Provides _protocol-independent translation from host names to socket addresses. If advanced functionality is not required, consider using getAddress for compatibility with older systems.
