<p>
The Domain Name System (DNS) name that Global Accelerator creates that points to a dual-stack accelerator's four
static IP addresses: two IPv4 addresses and two IPv6 addresses.
</p>
<p>
The naming convention for the dual-stack DNS name is the following: A lowercase letter a, followed by a 16-bit
random hex string, followed by .dualstack.awsglobalaccelerator.com. For example:
a1234567890abcdef.dualstack.awsglobalaccelerator.com.
</p>
<p>
Note: Global Accelerator also assigns a default DNS name, <code>DnsName</code>, to your accelerator that points
just to the static IPv4 addresses.
