Scenario brief
IPv6 adoption stalls when operators keep invisible v4 assumptions. You configure DHCPv6, wrestle with prefix lengths that looked fine on paper, and validate application behavior when eyeballs disagree. The storyline stays grounded in operational empathy.

Inside the lab
- Client VMs with quirky resolver behavior
- Prefix delegation scenarios with upstream changes
- Mentor prompts to document assumptions explicitly
- Capture review for neighbor discovery oddities
- Checklist for application owners about literal vs mapped addresses
- Hands-on with eyeballs timers without breaking user trust
- Written retro template for edge rollouts
Outcomes
- Ship an IPv6-first edge config with visible guardrails
- Coordinate with apps without blaming DNS by default
- Detect subtle breakage before users screenshot it
Logistics questions
Yes, but we focus on where v6 diverges mentally, not rehashing RIPv2 history lessons.
Cohort notes
“IPv6-First Edge made prefix delegation feel like choreography instead of chaos.”
