@Davide87 said in Search IP address in DHCP local network:

Such server has a dynamic IP assigned by the DHCP. Therefore, I don't know the IP address, but I know its hostname.

It looks like your problem is about networking, not Qt-related.

You need to ensure your network provides a good way for name resolution (i.e. DNS service). If your server is assigned a dynamic IP via DHCP that a DNS entry for such server name is keep up to date. This post could be a potential guide just in case.
