Dns host record not updating
The Internet Provider's DNS server will update its local cache so it knows the IP address the next time it receives a query.The website IP address is returned to your computer and this enables you to load the website in your browser.DNS caching: DNS caching is the length of a time that a DNS server will retain existing DNS records before checking for updates.The length of time that records are cached is usually determined by the TTL (see definition below) set by the authoritative name server, but some Internet Service Providers may have their DNS servers set to cache records for a longer period of time.It is similar to a zone file, but it is local to your computer system.
Hosts file: The hosts file is a text file in your computer's operating system that you can use to override external DNS records.
They are the primary source for your domain records.
Now that your Internet provider has found the authoritative name server, it is able to get the IP address for the domain.
