# IP addresses that must be opened in firewalls
{: #ips2open}

IBM® Cloud Logs data is sent using specific IP addresses.
{: shortdesc}

## IP addresses used by IBM Cloud Logs to connect to other services
{: #ip_to_services}

Use these IP addresses in firewalls and other configurations to ensure that the data received by your code, or another IBM service, originates only from IBM Cloud Logs.

### Private IP addresses used for IBM Cloud Object Storage, Event Notifications and Event Streams
{: #ip_private}

These private IP addresses are used to archive logs to IBM Cloud Object Storage, send events to IBM Cloud Event Notifications and stream logs to IBM® Event Streams for IBM Cloud®.
