Clearing DNS Cache on a Browser

Caching is a mechanism used by systems to improve performance, it’s the process of storing information locally to help expedite the response to requests. Assume most browsers have some form of caching. Because you are manipulating your DNS settings you have three options when you want to realize the benefits of the DNS change.

1. Restart the Router / Device
2. Wait until the DNS changes propagate (~10 – 15m) through your network
3. Flush your DNS cache (local machine and browsers)

These are not mutually exclusive, you can choose to do 1 and 3 together. Clearing your DNS cache will make sure that all new requests go to the new CleanBrowsing DNS IP’s in the place of the DNS entries cached locally.
