How to Check IP Addresses Used in B2C Commerce Environments

IP Addresses for Outbound Communication

When communicating from the B2C Commerce environment to external systems (such as service calls), the "POD Outgoing IP address" is used as the source IP address. Use these addresses when allowing traffic from B2C Commerce in the receiving side's firewall settings.
Refer to the following Knowledge Articles for the list of POD Outgoing IP addresses:

• Locations and Outgoing POD IPs for each Commerce Cloud POD [AMER PODs]
• Locations and Outgoing POD IPs for each Commerce Cloud POD [EMEA/APAC PODs]

IP Addresses for Business Manager

The hyphenated hostname used for the Business Manager URL (e.g., production-ap01-example.demandware.net) is routed through the Cloudflare CDN, so it resolves to a Cloudflare IP address.
Specific IP addresses are managed by Cloudflare and can be verified using nslookup or dig commands. Refer to the following for verification methods and IP address ranges:

• How do I find out the IP address of a Commerce Cloud B2C Instance?
• Cloudflare IP Ranges (External Site)

IP Addresses for Email Sending

A fixed IP address is assigned to the Business Manager hostname format, which uses periods as separators (e.g., production.ap01.example.demandware.net). This IP address is used as the source IP address when sending emails from the instance using the Mail.send() method.

• This IP address has a PTR record configured, allowing for reverse DNS lookups.
• It cannot be used to access Business Manager or the storefront via a browser.

IP Addresses for Storefronts

For storefronts where the embedded CDN is enabled (such as in Production environments), the CNAME record for the site's custom domain (e.g., www.example.com) points to the embedded CDN provider's (Cloudflare) domain. Therefore, the resolved IP address will be a dynamic IP address from Cloudflare.
You can verify this IP address using nslookup or dig commands.

Example:

$ dig +noall +answer www.example.com
www.example.com. 300 IN CNAME commcloud.prod-abcd-example-com.cc-ecdn.net.
commcloud.prod-abcd-example-com.cc-ecdn.net. 300 IN A 103.21.244.1

Note: The above is an example. This applies only when an external CDN is not configured in front of the B2C Commerce embedded CDN.
