Last updated: YYYY-MM-DD • Category: Config Guides

How to determine whether a deployment is stateful DHCPv6 or SLAAC/stateless DHCPv6, and how to verify client behavior.

Environment / assumptions

  • IPs anonymized (e.g., 10.0.x.0/30, fd00:xxxx::/64)
  • Simulated environment for demonstration (not production)

Procedure

  1. Checked RA flags (M/O) and DHCPv6 configuration for the interface (anonymized).
  2. Typed show ipv6 dhcp binding (or platform equivalent) to confirm stateful leases.
  3. Typed ipconfig /all (Windows) or nmcli dev show (Linux) to verify address assignment.
  4. Validated DNS assignment and renewal behavior with repeatable steps.

Verification

  • List the outputs that prove success.
  • Include command outputs (anonymized) when possible.
