This is a simple implementation of an LLMNR responder for the ESP8266 Arduino package. Only support for advertizing a single hostname is currently implemented. LLMNR is a very similar protocol to MDNS. The primary practical difference is that Windows systems (at least Windows 7 and later; perhaps earlier) support the protocol out-of-the-box, whereas additional software is required to support MDNS. However, Linux support is currently more complex, and MacOS X support appears non-existent.

/*
|
|
* This is an example of an HTTP server that is accessible via http://esp8266/
|
|
* (or perhaps http://esp8266.local/) thanks to the LLMNR responder.
|
|
*
|
|
* Instructions:
|
|
* - Update WiFi SSID and password as necessary.
|
|
* - Flash the sketch to the ESP8266 board.
|
|
* - Windows:
|
|
* - No additional software is necessary.
|
|
* - Point your browser to http://esp8266/, you should see a response. In most
|
|
* cases, it is important that you manually type the "http://" to force the
|
|
* browser to search for a hostname to connect to, rather than perform a web
|
|
* search.
|
|
* - Alternatively, run the following command from the command prompt:
|
|
* ping esp8266
|
|
* - Linux:
|
|
* - To validate LLMNR, install the systemd-resolve utility.
|
|
* - Execute the following command:
|
|
* systemd-resolve -4 -p llmnr esp8266
|
|
* - It may be possible to configure your system to use LLMNR for all name
|
|
* lookups. However, that is beyond the scope of this description.
