Class `std.socket.InternetHost`

InternetHost is a class for resolving IPv4 addresses.



class InternetHost
;

Consider using getAddress, parseAddress and Address methods instead of using this class directly.

Fields

Name	Type	Description
`addrList`	`uint[]`	These members are populated when one of the following functions are called successfully:
`aliases`	`string[]`	These members are populated when one of the following functions are called successfully:
`name`	`string`	These members are populated when one of the following functions are called successfully:

Methods

Name	Description
`getHostByAddr` (addr)	Resolve IPv4 address number.
`getHostByAddr` (addr)	Same as previous, but addr is an IPv4 address string in the dotted-decimal form a.b.c.d.
`getHostByName` (name)	Resolve host name.
`factory` (classname)	Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor.
`opCmp` (o)	Compare with another Object obj.
`opEquals` (o)	Test whether `this` is equal to `o`. The default implementation only compares by identity (using the `is` operator). Generally, overrides for `opEquals` should attempt to compare objects by their contents.
`toHash` ()	Compute hash function for Object.
`toString` ()	Convert Object to a human readable string.

Example

InternetHost ih = new InternetHost;

ih.getHostByAddr(0x7F_00_00_01);
writeln(ih.addrList[0]); // 0x7F_00_00_01
ih.getHostByAddr("127.0.0.1");
writeln(ih.addrList[0]); // 0x7F_00_00_01

if (!ih.getHostByName("www.digitalmars.com"))
    return;             // don't fail if not connected to internet

assert(ih.addrList.length);
InternetAddress ia = new InternetAddress(ih.addrList[0], InternetAddress.PORT_ANY);
assert(ih.name == "www.digitalmars.com" || ih.name == "digitalmars.com",
        ih.name);

assert(ih.getHostByAddr(ih.addrList[0]));
string getHostNameFromInt = ih.name.dup;

assert(ih.getHostByAddr(ia.toAddrString()));
string getHostNameFromStr = ih.name.dup;

writeln(getHostNameFromInt); // getHostNameFromStr
