FAQs
Why should I flush my DNS?
-
Most operating systems are designed to cache DNS records, which is generally a good practice as it allows for faster requests to a website. However, if DNS has recently changed, it may be necessary to flush the cache on your computer in order to retrieve the new DNS records.
What does flushing cache do?
-
Flushing DNS removes the local cache from your computer and allows it to retrieve the most recent cache that your Internet Service Provider is using. Flushing cache is also very useful when trying to speed up DNS resolution for a newly added or modified domain on your account.
