The development machine can then use\nADB over TCP/IP to access multiple VMs on the device. The ADB daemon on the host side can\nannounce the ADB presence on the guest VMs over mDNS by publishing ADB services.\nIn addition, the development machine can browse these services with ADB tool, which\nsupports mDNS device discovery (ADB version\n[31.0.2 or\nlater](https://developer.android.com/studio/releases/platform-tools#3102_april_2021)) to get the IP address and the port number on which adb daemon is listening and then\nconnect to the guest VMs.\n\nThe following commands can be used on the development machine to browse and connect to\nthe ADB services.\n\n 1. To enable mDNS discovery, run: Because ADB 31.0.2 disables mDNS discovery, you must enable mDNS discovery and then restart the ADB server. \n\n ```gdscript\n export ADB_MDNS_OPENSCREEN=1\n adb kill-server\n adb start-server\n ```\n2. To discover ADB services, run: \n\n ```scdoc\n adb mdns services\n\n List of discovered mdns services\n driver_vm\t_adb._tcp\t192.168.1.49:4444\n device_vm\t_adb._tcp\t192.168.1.49:3333\n ```\n3. To connect to the device, run: \n\n ```scdoc\n adb connect driver_vm._adb._tcp\n ```\n4. To list the connected devices, run: \n\n ```scdoc\n adb devices\n\n List of devices attached\n driver_vm._adb._tcp device\n ```"]]
