Configuring the Emulator's DNS Settings
At startup, the emulator reads the list of DNS servers that your system is
currently 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 OS X, 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. Note that this
usually means that the emulator ignores the content of your "hosts" file
(/etc/hosts on Linux/OS X, %WINDOWS%/system32/HOSTS
on Windows).
When starting the emulator at the command line, you can also use the
-dns-server <serverList> option to manually specify the
addresses of DNS servers to use, where <serverList> is a comma-separated
list of server names or IP addresses. You might find this option useful if you
encounter DNS resolution problems in the emulated network (for example, an
"Unknown Host error" message that appears when using the web browser).
