Key takeaways
- This tool queries public DNS (Domain Name System) resolvers from many locations at once and shows the A, AAAA, CNAME, MX and TXT records each one returns for a domain.
- Differing answers usually mean either a content delivery network answering per region, or a record change that has not yet expired out of every resolver's cache.
- The lookups run from more than 300 HostTracker locations, which is what makes a propagation gap visible at all.
- It is free, needs no login and no credit card.
- For continuous checks, see the DNS monitoring page: expected IP addresses ride on an Http, Ping or Port monitor.
