 ## Create CNAME record in your domain
 
-After the application gateway is created with its public IP address, you can get the DNS address and use it to create a CNAME record in your domain. You can use [Get-AzPublicIPAddress](/powershell/module/az.network/get-azpublicipaddress) to get the DNS address of the application gateway. Copy the *fqdn* value of the DNSSettings and use it as the value of the CNAME record that you create. Using A-records isn't recommended because the VIP may change when the application gateway is restarted.
