“DNS” is one of those terms you’ve most likely heard a few times, and you’re probably aware it’s something to do with the Internet, but possibly don’t know more than that. Essentially, DNS (or Domain Name System) is your PC’s way of translating website names (that people understand) into IP addresses (that computers understand). Your Windows 10 PC stores DNS data locally to speed up browsing, but there may come a time when you want to flush the DNS cache.
Why Would I Want to Flush My DNS Cache?
One of the main reasons is that when websites update their IP addresses, there’s a delay between that and the new IP address getting saved to your cache which means there can be times when sites don’t work because your cache hasn’t yet adapted to the changes online. So if you find a website not working, it’s a good idea to splash the cache, or rather flush the cache, but the other aquatic phrase sounds a bit better, and I think you’ll agree.
Also, if you want to hide your browsing habits online, it’s a good idea to flush your DNS because it stores the addresses to every site you visit. (That’s its entire purpose!) So if you’ve any confidential or naughty secrets in your browsing history, read on.
