Wildcard Domain Allowlisting
For customers whose firewall infrastructure supports wildcard DNS entries (e.g., *packnet.app), Packsize recommends allowlisting this reduced list of URLs. This method streamlines the configuration process and minimizes the ongoing maintenance as new services are introduced or endpoints change.
By permitting the following wildcard domains, customers can make sure comprehensive and reliable connectivity to PackNet services with minimal administrative overhead. Customers should consult their firewall documentation to confirm support for wildcard DNS entries as implementation details may vary.
The table below lists the ports and endpoints that must be allowlisted for IoT devices to connect to PackNet for customers whose firewall infrastructure supports wildcard DNS entries.
Note
When the environment does not support wildcard DNS allowlisting, refer to Fully Qualified Domain Name Allowlisting for the complete list of fully qualified domain names required for PackNet connectivity.
