LLMNR is a multicast protocol used on local area networks. It is the
method used by all major web browsers to resolve names that do not include
a dot ('.'). For example, if you attempt to open the web page:
http://my_freertos_device/index.html, then the web browser would send
an LLMNR request to try and resolve the name 'my_freertos_device'.
All LLMNR packets are sent to IP address 220.127.116.11 on MAC address
01:00:5E:00:00:FC, so the network interface (MAC) must be programmed to
accept packets on that address for LLMNR to function. In addition
must be defined as 1 in FreeRTOSIPConfig.h, and the
user must provide the implementation of a callback function xApplicationDNSQueryHook()
that takes a char pointer as a parameter and returns pdTRUE if the name
passed into the function matches a name used to identify the node.
