such as title, I see a lot on baidu said wlan MAC address changes, say what network environment has changed, your mobile phone will become the wlan MAC address, also see a lot of say this is a physical address, under normal circumstances is id is the same thing, unique, I am a little confusing, this thing under normal circumstances will not change, I tried to use mobile phones to connect three different wireless networks, did not change,
If get, what circumstances will change??

Is network card MAC address itself write die of hardware factory. But it is a programmable device. That is to say, although the factory was cured, but can be modified by some methods.

You said the scene, however, different wifi connection, must be won't change.
Change is only part of the artificially modified. (tool software or viruses)

CodePudding user response:

Should be won't change,

CodePudding user response:

Regular phone, usually is a constant

CodePudding user response:

Informal phone will change?

CodePudding user response:

Access to the Internet via mobile data is likely to change, to see whether the operator is to your public IP or operators of the internal IP mapping, just in the network configuration of MAC, not mobile phone in the curing of MAC

CodePudding user response:

After the test, the use of WiFi, generally will not change (testing too, didn't find change)
Under the condition of the use of mobile data, depends on how much is the Android version, get is not the same as the way is will be, directly new BufferedReader (.) readLine (); Will not change (Android 6.0 - Android 7.0 (not including)), 7.0 after get way different, test a few mobile phones, will change,
