Enabling IPv6 for Hosted Apps
Page last updated:
This topic describes how to enable IPv6 support for hosted apps.
The procedure described below allows apps deployed to VMware Tanzu Application Service for VMs (TAS for VMs) to be reached using IPv6 addresses.
Note: Amazon Web Services (AWS) EC2 instances currently do not support IPv6.
TAS for VMs system components use a separate DNS subdomain from hosted apps. These components currently support only IPv4 DNS resolved addresses. This means that although an IPv6 address can be used for app domains, the system domain must resolve to an IPv4 address.
To enable support for IPv6 app domains:
Set up an external load balancer for your TAS for VMs deployment. For more information, see Using Your Own Load Balancer.
Configure DNS to resolve app domains to an IPv6 address on your external load balancer.
Note: Your IPv4 interface for the system domain and IPv6 interface for app domain can be configured on the same or different load balancers.
Configure the external load balancer to route requests for an IPv6 address directly to the IPv4 addresses of the Gorouters.
The following diagram illustrates how a single load balancer can support traffic on both IPv4 and IPv6 addresses for a TAS for VMs installation:
