A strange question about the Windows network configuration protocol, which may not exist?

Question

Computer networks

Hello! I understand that I'm taking a risk, but I'll ask:
I vaguely remember that windows can accept network settings not from DHCP, but from a special web server. This web server announces itself to broadcast addresses, clients go to it and receive settings. The meaning of all this action is the ability to quickly reconfigure the network, while using static settings. It seems that there is even an attack scenario using this feature.
I admit the possibility that I dreamed all this, however, if you have heard of such a technology, feel free to share.
UPD.
It all happened anyway. This is how I perverted WPAD

Answer 1

You are probably confusing with the WPAD proxy en.wikipedia.org/wiki/Web_Proxy_Autodiscovery_Protocol

Answer 2

How are you going to access a web server without having an ip address? Where will he answer you?
From similar, with a webserver, I know WPAD (Web Proxy Auto Discovery). Proxy server settings are automatically detected - a Javascript program is downloaded from the web server, which for each domain name or ip address determines which proxy server to use to connect, or go directly. But the network for this must already be configured - statically or dynamically (in the latter case, a special option can be passed to the client indicating the address of the proxy auto-configuration server).

Answer 3

Apparently it is:
en.wikipedia.org/wiki/Bootstrap_Protocol

Answer 4

Of the alternatives to dhcp for network autoconfiguration, only Zeroconf comes to mind . However, it is unlikely that we are talking about him.
