Frequently Asked Questions
Quick answers for common checks and interpretation questions.
How long does DNS propagation usually take?
It depends on TTL and resolver behavior, but updates often stabilize within minutes to 24 hours.
Does this tool flush DNS caches?
No. It only reads resolver responses so you can observe real-world propagation states.
