In the Plus and Enterprise versions of Zendesk, access to your Zendesk can be restricted to specific IP addresses. This means that users from these IP addresses are the only users allowed to log in to your Zendesk. This includes all users.
You can specify ranges of IP addresses, separating each range with a space. Two methods are available to specify a range. The first is to use asterisk (*) wildcards. An IP address consists of four numbers separated by periods, such as 192.168.0.1. You can substitute a single asterisk character (*) for any number group to let Zendesk know that it should accept any value in that space. For example, 192.*.*.* allows any IP address whose first number is 192.
The second way to specify an IP range is to use IP subnet mask syntax. For example, 192.168.1.0/25 specifies all the IP addresses between 192.168.1.0 and 192.168.1.127.
