Net.hostname is now empty and the dhcp client no longer sends a hostname See Android 8 Privacy Changes and Security Enhancements: Since Android 8 – when android_id became unique to apps – net.hostname is no more set, so a null is sent in DHCPREQUEST. In Android 6 net.hostname continued to be used (1, 2, 3, 4) in new Java DHCP client when native dhcpcd was abandoned and later service was removed in Android 7.

When I wanted to configure a hostname to the device I found out with the latest version. Then I found this thread which was more what I was looking for, which tells me how the name is retrieved … “DHCP Snooping”.Īlright, so taking a look at the DHCP server, I noticed it was indeed empty names on the IPs that were given out.ĭidn’t take me long to determine that it was Android devices.
