Thank you for making these videos. Great content from a great channel.

Interesting video. Is there a way to sniff traffic on a Samsung Galaxy smartphone to see it connect to these SGW/PGW in real time?

Hi Russell. Excellent videos explaining the use of DNS in EPC. Is it possible for you to share the zone files either here or on github. I just got a bind server up and wanted to experiment. Thanks

Hi Russell, I hope you are doing great. Would you let me know what is the interface name between MME and DNS and what protocol are they using ? Thanks for your help.

[@QuadraticSquared]

The protocol is actually DNS, where the interface doesn't have a formal name. The closest think you'll find to an interface specification would be 3GPP TS 29.303.
