Dns records updating
Once the DNS cache is empty, the computer will start asking for new data from the DNS server and it will build DNS cache from the beginning. An alternative method for accessing the command prompt with an administrator level is available on this page.
Flush DNS command on Windows 8 is the same to DNS flush command on Windows 7, the difference is only in how to open the command prompt.
When you access a website, the computer will perform DNS caching, which means that the data in the form of domain name and IP address of the website that you access are locally stored in the computer for a period of time, so when you open a web page that has previously been opened it will feel faster because the computer has remembered the IP address and it does not need to contact the DNS server.
We suggest waiting up to 24 hours for the DNS cache to be fully refreshed. When the DNS refreshes according to its TTL, the propagation is complete and your site will load.
Seamlessly integrate Azure-based services with corresponding DNS updates and streamline your end-to-end deployment process.
Azure DNS uses a global network of name servers to provide fast responses to DNS queries.
The first thing we will want to configure is an A record. This A record will be pointing to the Public IP Address of the service that is accepting your mail.
Now why did I say mail service instead of mail server?
