"Chat: If you want to guarantee Chat is turned off for all users on your network, in your router or proxy server map www.bing.com to nochat.bing.com. If you want to guarantee Chat is turned off for all users on your network plus all users are set to strict SafeSearch, in our router or proxy server map www.bing.com to nochatstrict.bing.com. The above settings will guarantee that strict SafeSearch results and/or Chat, as applicable, are returned or turned off for all queries to this IP and the SafeSearch controls are disabled. Similarly, mapping edgeservices.bing.com to the same subdomain forces the same policies in the Edge sidebar."
