# Domain Name
General techniques such as applying for a domain name and resolving domain names are not discussed in this document.
Here we introduce a more useful domain name feature of Azure: Azure provides DNS services for each virtual machine.
When the VM is configured with a dynamic IP address, the IP address may change each time the VM is restarted. As a result, the domain name needs to be re-resolved, which brings unnecessary trouble to the operation and maintenance. Azure's DNS function is to help us avoid this problem.
- Login Azure Portal, Open the Overview of VM, Click the "Configure" of DNS name
- Input your DNS name label, e.g "mysite", then Save it
- Complete this setting, you can visit URL http://mysite.centralus.cloudapp.azure.com to this VM's applications
