I have a very strange problem. My esp has node mcu firmware. It boots up nicely and gets IP address from the router, but when i see it in my router it doesn't show up. Also when i telnet in to router and give "show ARP ", i don't see any entry for esp. I am able to figure out the IP address from serial. Init.lua contains sample code of httpserver and i can navigate easily.
I don't know what to do. any suggestions ??

Are you perhaps not recognising the Mac number properly?

There is no mention of the IP or even the MAC address. Also my ESP has the sample web-server code for turning on and of the GPIO pins. I am attaching the snapshot of the arp command of the router. Router is DLINK DIR-600M

arp table won't show every devices on the network until there packet transaction between the device and the host where you look at it arp table. Also, the device will disappear from the cache after a certain arp delay.
Simply do a ping first and then show arp.
