# IP Address related inquiries

1. **What is Postman’s IP address?**

   * We do not provide our IP address, you can whitelist our domain name. If you really need our IP address, you can resolve the domain to find the IP address, but you will be responsible for updating it if it changes.

2. **Does Postman allow me to bulk upload our IP addresses?**

   * No,  you will need to upload them individually.

3. **What IP can be whitelisted (Internal or public)?**

   * Static Public IP address, do note that you will be calling our API endpoints using this IP address that you have whitelisted.

4. **When do we submit our IP addresses for whitelisting?**

   * This will be done in the campaign creation flow. Refer to our [API documents](/postman-v2-admin-portal-for-api-users-mop/campaign-settings.md#integrations-ip-address-whitelisting) for more information.
