Configure emulator DNS settings

At startup, the emulator reads the list of DNS servers that your system is using. It then stores the IP addresses of up to four servers on this list and sets up aliases to them on the emulated addresses 10.0.2.3, 10.0.2.4, 10.0.2.5, and 10.0.2.6, as needed.

On Linux and macOS, the emulator obtains the DNS server addresses by parsing the file /etc/resolv.conf. On Windows, the emulator obtains the addresses by calling the GetNetworkParams() API. This usually means that the emulator ignores the content of your hosts file (/etc/hosts on Linux and macOS, %WINDOWS%/system32/HOSTS on Windows).

Manually specify DNS servers

When starting the emulator from the command line, you can use the -dns-server <serverList> option to manually specify the addresses of DNS servers to use.

  • <serverList> is a comma-separated list of server names or IP addresses.
  • This option is useful if you encounter DNS resolution problems in the emulated network, such as an "Unknown Host error" message when using the web browser.
