Dynamically assigned TCP/IP parameters

Updated: May 06, 2022

When you add a host to the network or connect your host to the Internet, you need to assign an IP address to your host and set some other configuration parameters.

There are a few common mechanisms for doing this:

Along with your IP address, the servers implementing these protocols can supply your gateway, netmask, name servers, and even your printer in the case of a corporate network. Users don't need to manually configure their host to use the network.

QNX Neutrino also implements another autoconfiguration protocol called AutoIP (zeroconf IETF draft). This autoconfiguration protocol is used to assign link-local IP addresses to hosts in a small network. It uses a peer-negotiation scheme to determine the link-local IP address to use instead of relying on a central server.
