  WiFiMDNSResponder.h - Library for Arduino Wifi shield.

  Based on and modified from

  1) WiFi101 Library                 https://github.com/arduino-libraries/WiFi101

  Forked then modified by Khoi Hoang https://github.com/khoih-prog/WiFi101

  Port of CC3000 MDNS Responder to WINC1500.
  Author: Tony DiCola

  This MDNSResponder class implements just enough MDNS functionality to respond
  to name requests, for example 'foo.local'.  This does not implement any other
  MDNS or Bonjour functionality like services, etc.
