Function std.socket.getAddressInfo
Provides protocol-independent translation from host names to socket

for compatibility with older systems.
Returns
Array with one AddressInfo
per socket address.
Throws
SocketOSException
on failure, or SocketFeatureException
if this functionality is not available on the current system.
Parameters
Name | Description |
---|---|
node | string containing host name or numeric address |
options | optional additional parameters, identified by type:

Example
// 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);
