In a connected world, the DNS perimeter has drastically expanded as global workforces now utilize multiple devices to connect to the Internet – increasing your network’s load and exposure. This expansion not only increases performance demands, but also limits your visibility into the threats that are targeting and infecting your networks, ultimately putting your organization in harm’s way. Despite your current safety measures and security provisions, malware still bypasses network defenses, costing you more time and money on cleanups – as well as hindering network performance.

If you have a router on your network, we recommend that you modify your DNS settings there. This way, you typically only have to make one change, as opposed to making a change to each computer or device on your network.
Login to your router
To login and configure your router, you need to use a web browser. Simply type in your routers IP address to get started.
If you don't know the IP address for your router, it is typically one of the following:
If you have forgotten your router's username and/or password, the most common username is "admin" and the password is either blank, "admin" or "password." Most new routers now have unique usernames and passwords written directly on them.
Find the DNS server settings
Look for "DNS" next to a field which allows two or three sets of numbers (these fields may be empty).
3. Put in your desired Free Recursive DNS server IP addresses and click save/apply
Please write down your current DNS settings, in case you want to return to your old settings for any reason.
