Frequently asked questions
- What is RDAP vs classic WHOIS?
- RDAP is a structured registration data protocol many registries use today. This tool queries RDAP where available and shows DNS records alongside it.
- Which DNS record types are shown?
- Common types include A, AAAA, CNAME, MX, NS, TXT, SOA, CAA, DS, TLSA, and SRV when present. DMARC/SPF hints are derived from TXT where applicable.
- Can I share a lookup?
- Yes. Use the shareable ?q= URL pattern from the tool so someone else opens the same domain view.
- Is DNS data guaranteed accurate?
- Results reflect what resolvers return at query time. TTLs, caching, and split-horizon DNS can make answers differ from other networks.
- Does DNS lookup replace a security audit?
- No. It is a read-only diagnostic for administrators and curious users—not a replacement for professional security review.
