You may have already used Zeroconf technology and mDNS without realizing it.
It allows you to automatically assign a hostname of the type .local to a machine without configuring DNS, making it easy to access without knowing the IP address.
This is the case, for example, on Raspberry Pi (raspberrypi.local).
This can be particularly useful when the DHCP client is enabled on the controller; you simply enter its name to access it.
This technology can be implemented on WAGO controllers using “avahi”.
This package can be installed via an IPK.
Zeroconf/mDNS is supported (and normally enabled) on Windows, Android, and iOS machines.
To install it, go here:
It can also be useful for generic applications where you can prename your plc : .local
