[android-security-discuss] Bluetooth PAN DNS Hostname to pull from DHCP rather than the device creating its own?

[Rod Kashani]

Hey All,

So I have a bluetooth pan on a raspberry pi which gives an ip and Internet
connection to an android, in this case the S6 edge. I am given an ip
address, however I can't communicate with other devices on the network. I
do receive Internet though. It seems the android is assigning itself a dns
hostname, which separates itself from the rest of the network. I could be
wrong, but when laptops connect to the same pan network, they are given the
dhcp information from the router and they can communicate over the network
with the ip's being given to them from the bluetooth access point.

The laptops have a hostname of TP-link_D5DE and the android has
android_9xxxxxx

Can the android adopt dhcp hostname info via Bluetooth pan? Can I change
this name? Is it possible without root if so?

I understand there was somewhat of an issue with dhcp "hooks" back in the
day where the bluetooth controller couldn't retrieve this information but I
read that on a forum which was a few years old and also read it was fixed
on newer versions of android.

Thanks!
