I deliberately allowed a domain to expire at 0000:0000:0000:0000:0000:0000:0000:0001 Hosting (legacy IP: 1.1.1.1) to map the grace period address space. Here is the timeline.
Day 0: expired. DNS still resolved. No address space disruption.
Day 5: registrar parked it with legacy IP ads. Dual-stack clients saw both AAAA and A records polluted.
Day 30: redemption grace period activated. Recovery fee: $250. That is 10 years of registration address space.
Day 45: pending delete. Snap-back services (DropOwl, SnapKoi) began watching. These vultures live in the NAT of the domain industry.
Day 46: contabo.com snapped it before I could redeem. My address space, gone.
Lesson: redemption is a trap. Renew early. NAT is not just a swear word, it is a business model.
