Is your domain resolving correctly?
See the evidence behind a DNS answer: public addresses, IPv4 and IPv6, provider hints, canonical chain, nameservers, SOA, TTL, and lookup latency.
Free, no login required
Run a DNS check
Enter a domain or URL. The check uses the hostname and does not expose private lookup data.
What you get
Understand the delegation, not just the answer.
See whether the target returned IPv4, IPv6, or both.
The report explains what one lightweight resolver check can and cannot prove.
Can this identify the registrant?
No. Registrant data is often private and is not part of this public probe. WHOIS and registrar intelligence are planned separately.
Does this test every country or carrier?
No. Multi-region and carrier-aware probes are planned capabilities and are not live in this preview.
