What is the default address range used in Z-Tunnel 2.0?

The default address range used in Z-Tunnel 2.0 is 0.0.0.0/0. This designation represents all possible IP addresses in IPv4, essentially covering the entire Internet. The Z-Tunnel is designed to provide secure internet access for users, and by using this address range, it can route any traffic from any source to the Zscaler cloud for inspection and policy enforcement.

This configuration is pivotal because it ensures that all user traffic, irrespective of the originating IP address, passes through the Zscaler security layers. This comprehensive coverage allows organizations to maintain consistent security policies across all endpoints, enhancing their overall digital transformation strategy by securing cloud-based applications and data.

Other address ranges mentioned, such as 192.168.1.0/24, 10.0.0.0/8, and 255.255.255.255/32, are either reserved for specific local network uses or represent limited ranges of IP addresses. They do not facilitate the wide-reaching applicability that 0.0.0.0/0 provides, making them unsuitable as the default setting in Z-Tunnel 2.0.
