Using QHostInfo to get host name from an IP

Hi all!

I am trying to get the host name from a IP inside my LAN using QHostInfo.

This is my code:

Code:

---

bool rede::verificaIP(QString ip)
{
    info.setAddresses();
    QHostInfo info = QHostInfo::fromName(ip);
 
    qDebug() << "IP:" << info.hostName() << info.addresses();
 
    return false;
}

---

The ip parameter is 192.168.1.91

But the result is:
IP: "192.168.1.91" (QHostAddress("192.168.1.91") )

The function does not returns the host name

Can anyone help me?

Thanks a lot.

fromName retrieve the IP address from name

Looks up the IP address(es) for the given host name.

To get the host name from a IP address you need to use QHostInfo::lookupHost

EDIT: I made a test now and in my network also fromName returns the host name from the IP...

Yes, its in the QhostInfo documentation, but in my network it does not happen. Can Anyone help my please. Thanks a lot

What is the correct hostname?

Does the hostname correctly resolve to the address?

Cheers,
