Role of


Do you know what the role is of Zscaler App’s frequent DNS queries for A record of hostname against DNS server IP address

I can’t find any documentation that explain why it’s doing this.

Thank you,


That is a Z-App test to verify that there are no internal firewalls blocking Z-App traffic. If there was a failure it would display a FW Error.

Thank you,
