Anti-pollution DNS

NOTE

CMCC users are likely unable to use it in system DNS settings, since most systems uses UDP port 53. If you have a local DNS client which can specify ports, see if you're lucky on port 2333.
All results are authoritative, this means we do NOT provide proxy services with our DNS.
We use 119.29.29.29 (for sites in mainland China) and 8.8.8.8 (for rest of them) as our sources. We also support EDNS and DNSSEC.

Main server: 140.143.226.193

Shadowsocks

Please install Shadowsocks client before using (Windows/Android/Linux Qt5). We do NOT support Outline by Google Jigsaw.
Please download v2ray-plugin (Android/other platforms) if you want to use configurations below that begins with "V2RAY". For iOS users, please consider Shadowrocket TestFlight version, as we do NOT support Vmess clients; For other platforms, please extract the file from the archive and rename the executable file to v2ray-plugin (don't forget .exe if you are on Windows), then place the file under the same folder with Shadowsocks.exe (if you are using Windows) or anywhere in $PATH (if you are on other platforms). Android clients might display as "Unknown plugin", which is okay (or you can choose "v2ray" manually if you want to).
Please download kcptun plugin (Android/other platforms) if you want to use the "KCPTUN" configuration. For other platforms, please extract the files from the archive and rename the executable file that begins with client to kcptun (don't forget .exe if you are on Windows), then place the file under the same folder with Shadowsocks.exe (if you are using Windows) or anywhere in $PATH (if you are on other platforms).
You can also use the "PLAIN" configuration (no plugin required), so you don't have to download anything besides Shadowsocks client itself. Don't use an old version of the client, though - it might not support the encryption method we are using.
Finally, import the configuration below and you should be good to go! Most clients support importing from clipboard or scanning a QR code, the latter of which is available by simply clicking links that begin with ss:// below. But, if you do have to configure manually:
Required for all configurations: server address is one of the H3 headers below (ss-*.googlehosts.org), password googlehosts, encryption method chacha20-ietf-poly1305;
V2RAY-HTTP: port 2333, plugin v2ray-plugin, plugin options host=ss-*.googlehosts.org (replace * with the same digit in the server address);
V2RAY-HTTPS: port 2334, plugin v2ray-plugin, plugin options tls;host=ss-*.googlehosts.org (replace * with the same digit in the server address);
V2RAY-QUIC: port 2335, plugin v2ray-plugin, plugin options mode=quic;host=ss-*.googlehosts.org (replace * with the same digit in the server address);
KCPTUN: port 2336, plugin kcptun, plugin options crypt=salsa20;mode=normal;mtu=1200;parityshard=0;dscp=46;nocomp;
PLAIN: port 2337, leave "plugin" and "plugin options" empty.

Telegram MTProto

We've dropped support for SOCKS5 proxies on March 4, 2019 due to continuous blockage by GFW.
Visit status.googlehosts.org for server online status. You might be unable to view the page if your browser doesn't support TLS 1.3.
Server #6 and #7 are optimized for users in mainland China (please note that these two servers might use our relay servers located in mainland China), while server #8 and #9 are optimized for users in Iran.
Clicking the link below should bring up Telegram client and import the proxy automatically; you can also copy the link to any chat and click it there. But, if you do have to configure manually: proxy type "MTProto", hostname is one of the lines below (tg-*.googlehosts.org), port 2335, secret 7hFCDxWP-ehFO9fQguLNzup0Zy0xMC5nb29nbGVob3N0cy5vcmc.
