While tracing/sniffing for something, I mirrored all packets of my mobile phone to Wireshark and I was was really astonished to see many multicast DNS requests (_googlecast._tcp.local) from my mobile …
As you see, these are more than 15 packets per second, which leaded at once to following 3 thoughts:
- That can’t be good for the battery
- The mobile is sending this surely not only in my home network but also in hotspot networks … I don’t like that for security/privacy reasons (specially what happens if the phone gets an answer and maybe sends more info about itself)
- I’m not using Chromecast anywhere
Which leaded at once to the question:
- How can I disable this?
So I went on a search trough the Internet …. but I was not able to find a solution. So the question to the community .. has someone an idea how I can disable that?
ps: I found only one guy asking the same question in the xda developers forum
