When you type an address such as e-lins.com into your browser, your computers uses DNS to look up and translate that name into a computer-friendly IP address. Sometimes, though, the servers your computer uses to look up that information can have issues, or go down entirely. Check out our guide to finding the fastest DNS servers for more information. If your default DNS servers aren’t having problems, then you probably won’t find too much of an improvement with an alternative server — but it might speed up your browsing by a few milliseconds, at least. One reminder: if your provider offers unmetered browsing for services such as iView, be cautious when changing DNS details, since this can mean those services are metered and will count against your download allowance.
