It often occurs with the present perfect. Once the DNS server has found the IP address, it sends the address back to the browser.

13. Language Work: Time clauses 3. We can use until to link an action and the limit of that action: The packets are passed from router to router until they reach the web server. 4. We can use before to show that one action precedes another: The packets may travel by different routes before they reach the Web server. If the subjects are the same in both actions, we can use a participle : The packets may travel by different routes before reaching the Web server.

14. Language Work: Time clauses 5.We can use as to link two connected actions happening at the same time: As the individual packets reach the Web server, they are put back together again.
