Zscaler is expanding its Global ZIA Service Edge IP address footprint and introducing the following IPv6 addresses on the Configuration page. The expansion of existing Global ZIA Service Edge IP addresses to include IPv6 addresses provides the scalability and reliability required to meet the growing demand for global connectivity on our cloud platform. This expansion benefits users who utilize the no-default route architecture in their network. Additionally, Global ZEN IP addresses are now known as Global ZIA Service Edge IP addresses.
|
What are the Global IPv6 address ranges?
|
CIDR |
2a03:eec0:1211::a2 |
2a03:eec0:1211::a3 |
2a03:eec0:1211::a4 |
2a03:eec0:1211::a5 |
2a03:eec0:1211::a6 |
2a03:eec0:1211::a7 |
2a03:eec0:1211::a8 |
2a03:eec0:1211::a9 |
|
|
|
If you intend to forward traffic to any of the new IPv6 Global ZIA Service Edge IP addresses, you might need to configure your firewall to allow traffic to them and make appropriate adjustments in routing.
If you do not intend to use the new IPv6 Global ZIA Service Edge IP addresses for forwarding traffic to Zscaler, no action is required
|
When will the service be provisioned with these new IP address ranges?
|
The services through the new IPv6 addresses become available any time on or after the availability date listed earlier. An advance notification via Trust Portal post will also be sent. If you have not signed up to receive Trust Portal posts, you can subscribe to them here.
