| 353 | \class QHostAddress | - |
| 354 | \brief The QHostAddress class provides an IP address. | - |
| 355 | \ingroup network | - |
| 356 | \inmodule QtNetwork | - |
| 357 | | - |
| 358 | This class holds an IPv4 or IPv6 address in a platform- and | - |
| 359 | protocol-independent manner. | - |
| 360 | | - |
| 361 | QHostAddress is normally used with the QTcpSocket, QTcpServer, | - |
| 362 | and QUdpSocket to connect to a host or to set up a server. | - |
| 363 | | - |
| 364 | A host address is set with setAddress(), and retrieved with | - |
| 365 | toIPv4Address(), toIPv6Address(), or toString(). You can check the | - |
| 366 | type with protocol(). | - |
| 367 | | - |
| 368 | \note Please note that QHostAddress does not do DNS lookups. | - |
| 369 | QHostInfo is needed for that. | - |
| 370 | | - |
| 371 | The class also supports common predefined addresses: \l Null, \l | - |
| 372 | LocalHost, \l LocalHostIPv6, \l Broadcast, and \l Any. | - |
| 373 | | - |

| 700 | address does not contain a scope ID, an empty QString is returned. | - |
| 701 | | - |
| 702 | The IPv6 scope ID specifies the scope of \e reachability for non-global | - |

| 714 | | - |
| 715 | \li Link-local: Addresses that are local to the network interface | - |
| 716 | (\e{link}). There is always one link-local address for each IPv6 interface | - |
| 717 | on your host. Link-local addresses ("fe80...") are generated from the MAC | - |
| 718 | address of the local network adaptor, and are not guaranteed to be unique. | - |
| 719 | | - |
| 720 | \li Site-local: Addresses that are local to the site / private network | - |
| 721 | (e.g., the company intranet). Site-local addresses ("fec0...") are | - |
| 722 | usually distributed by the site router, and are not guaranteed to be | - |
| 723 | unique outside of the local site. | - |
