+On this page, we will explore the Multicast DNS feature. MDNS is very useful for connecting to a device of which you do not know the IP address, and works similar to the Domain Name System, on a local network without the need for a DNS server. You can use the `hostname.local` url to connect. To be able to use MDNS on your computer, you might need some additional software.

+## Use MDNS for a Telnet connection
+```python
+from network import MDNS
+MDNS.init()
+MDNS.set_name(hostname ="pycom", instance_name="pycom")
+MDNS.add_service("_http",MDNS.PROTO_TCP, 80)
+MDNS.add_service("_telnetd", MDNS.PROTO_TCP, 23)
+```
+
+When this is running on your development board, you can go to your terminal and try `ping pycom.local`. The second service activate the telnet link, so you can also try `telnet pycom.local` and connect to the REPL through this method!

 * **LoRaWAN mode** implements the full LoRaWAN stack for a class A device. It supports both OTAA and ABP connection methods, as well as advanced features like adding and removing custom channels to support "special" frequencies plans like the those used in New Zealand. There are two basic ways of accessing the LoraWAN network:
