Overview
All outbound IP addresses used by our systems are managed under the domain:
ips.commbox.io
CommBox maintains this domain and ensures that all our relevant IP addresses are correctly configured.
For security and verification purposes, each IP address also has a corresponding PTR (reverse DNS) record. This ensures a double verification mechanism for our IPs.
IP Addresses
The following are the IP addresses used by CommBox:
- 34.253.247.49
- 54.72.111.9
- 54.73.245.187
- 46.137.14.237
- 52.19.95.133
Best Practice
-
When whitelisting the CommBox IP, use the CommBox domain instead of the IP
Eg. from ips.commbox.io port 8443 allow to datapower.contoso.com -
When possible, enable PTR verification on the addresses under ips.commbox.io
