DNS lookup for any domain

Every record type in one query, read from the resolver rather than from a cache we keep. Mail, verification, delegation and certificate-authority records are all here, alongside what the registry says about the name itself.

All the record types, not just the common two

A and AAAA answer where a name points, but most real questions are elsewhere: MX for where mail goes, TXT for the SPF and DKIM records that decide whether it arrives, NS for who is authoritative, SOA for the serial that tells you whether a change has propagated, and CAA for which authorities may issue certificates for the name.

Registry data alongside the records

WHOIS and RDAP answer a different question from DNS: who registered the name, when, through whom, and when it expires. RDAP is the structured successor and is what we prefer where a registry offers it, because a parsed answer beats a paragraph of formatted text that changes shape by registrar.

What a stale answer looks like

DNS is cached at every hop, so a record you changed an hour ago can still be answered from somewhere. Reading the SOA serial is the honest way to tell whether what you are seeing is current, and it is why that record is shown rather than hidden behind an advanced toggle.

Questions

Do you store what I look up?

A lookup is answered and not kept against you. A scan is kept — the account, the target, the time and the authorisation statement — because that record is what an abuse report is answered with, and keeping it is the condition of offering the feature at all.

What can a website see about me?

Your address, and whatever your browser volunteers: its user agent, language, screen size, time zone and a long list of capability flags. Together those are often distinctive enough to recognise a returning visitor without a cookie. The home page shows you what we can see, which is what any site can see.
