Esxi 5.5 License Key Github →

Purchase legitimate licenses: Obtain ESXi 5.5 licenses directly from VMware or authorized resellers to ensure compliance and avoid intellectual property infringement.
Use evaluation versions: Consider using evaluation versions of ESXi 5.5 for testing and development purposes.
Report shared license keys: Report any shared license keys on GitHub or other platforms to VMware or the platform administrators.

ESXi hosts can run in evaluation mode (full features) for a limited trial period.
To move to licensed mode, a license key (serial) is applied via vSphere Client, vSphere Web Client (where supported), or via host client/CLI.
Licenses are associated with a vCenter Server license manager in environments using vCenter, or applied per-host in standalone setups.
Feature limitations depend on the license edition (e.g., CPU/socket limits, clustering, vMotion, HA).
Persistent licensing metadata is stored on the host and in vCenter if managed centrally.
