DNS TTL Planner
Enter your event type and current TTL to get a step-by-step timeline for lowering and restoring DNS TTL safely. Runs entirely in your browser.
🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.
Recommended plan
Example shown — replace it with your own current TTL and event.
How it works
- Choose the type of DNS change you're planning.
- Enter your record's current TTL.
- Get a step-by-step timeline for lowering and restoring TTL safely.
Planning calculates how long before your change to lower the TTL — based on the current TTL value — so old cached records expire everywhere before you make the real change, minimizing propagation delay and downtime risk.
FAQ
Is my DNS data uploaded anywhere?
No. Planning happens entirely in your browser — nothing is sent to a server.
What is DNS TTL?
Time to live — how long, in seconds, resolvers are allowed to cache a DNS record before checking for updates again.
Why lower TTL before a planned change?
A lower TTL means resolvers check for updates sooner, so once you make the actual change, it propagates faster — minimizing the window where some visitors see stale records.
How long before the change should I lower the TTL?
At least as long as your current TTL, so the old, longer-cached value has fully expired everywhere before you make the real change.
How we compare

A DNS dashboard changes the record but doesn't plan the timing. DNS TTL Planner gives you the exact schedule to minimize downtime.
