This tool runs a short series of DNS leak checks to identify the resolver IPs that answer your DNS requests. If you see only one resolver, your DNS is consistent. If you see multiple resolvers, you may be using split DNS, a VPN, or a misconfigured network.
Why It Matters
- Performance: A slow resolver can make websites feel sluggish.
- Privacy: Your resolver can see which domains you visit.
- Troubleshooting: Resolver changes can explain inconsistent access to websites.
If you want to test DNS record changes, try the DNS Propagation Checker. To inspect a domain’s records, use DNS Lookup.
