Frequently Asked Questions
How often does the data on this page update?
The live counters refresh every 15 minutes straight from the scanner fleet and the ClickHouse cluster. The underlying IPv4 allocation data is checked against MaxMind GeoLite2 every day (a new release is imported as soon as it is published) and against the RIR delegation files every six hours.
How does WorldIP.io scan the entire IPv4 address space?
A fleet of scanner nodes across North America, Europe and Asia-Pacific each runs an independent, continuous reverse-DNS (PTR) scan over its own slice of the allocated space. Results stream into a globally replicated ClickHouse cluster, so every region writes close to home while the whole dataset stays queryable in real time.
Do you connect to or probe the addresses you scan?
No. We only issue standard DNS PTR queries against the .in-addr.arpa zones — the same public lookups any recursive resolver performs. No ports are scanned and no connection is made to the addresses themselves.
