1. Claim
Pick a label. It is live in seconds — a real A / AAAA / CNAME record, not a redirect.
2. Point
Use the DynDNS2 endpoint your router already knows, or the REST API. IPv4 and IPv6.
3. Renew
One click, once every 30 days. Reminder lands in your inbox with a no-login link.
Why the manual renewal?
Because it is the cheapest anti-abuse system in existence. Phishing kits, spam C2s and forgotten experiments do not click a button once a month — dead names simply fall off.
What that buys you: no fake accounts, no queue, no ads, no "free tier" that expires in 14 days. Expired names stop resolving, get 7 days of grace, then return to the pool for someone else.
Renewal only extends the clock. It stays free — there is nothing to pay, ever.
