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.
