About this network

IBM Cloud's infrastructure network (SOFTLAYER) — the former SoftLayer hosting provider that IBM acquired and rebranded as IBM Cloud.

What it's used for

• Hosting customer workloads on IBM Cloud: bare-metal and virtual servers, managed services, and enterprise infrastructure.

Notable

• An IP here means IBM Cloud is the host; the workload belongs to a customer.
• The SOFTLAYER handle persists from the acquired brand, which is why lookups show SoftLayer rather than IBM.

Interesting

• SoftLayer was known for automated bare-metal provisioning, a capability IBM folded into its enterprise cloud strategy.
