@talalong consumption wise it doesn't make a big difference to open a UDP server or not. If you have strict energy requirements you might rethink some other components though.

Are you sure that `%tap0` is the correct network interface? @smlng didn't we face problems with link local IPv6 Linux - RIOT recently?

You register a UDP server. Have a look at [the sock API](https://doc.riot-os.org/group__net__sock__udp.html) or the implementation of the [`gnrc_pktdump`](https://github.com/RIOT-OS/RIOT/blob/master/sys/net/gnrc/pktdump/gnrc_pktdump.c) module whichw as mentioned by @taherrera. I'd recomment the first option though!
