What is the difference between A and AAAA?

A returns an IPv4 address, AAAA returns an IPv6 address. Most user-facing domains have both today, with AAAA driving the IPv6-only audience.

It is the time-to-live in seconds — how long a resolver is allowed to cache an answer before re-querying. Common values are 300 (5 minutes) for fast-changing records and 86400 (24 hours) for stable ones.

My DNS change is not visible yet — bug?

Caches along the path still hold the old answer until the TTL expires. The lookup tool sees cached data, not always the live authoritative value.

Can I look up SOA, SRV, or DNSKEY records?

The tool ships with the six most common types today. SOA and SRV are next on the roadmap; if you need them now, use dig against the authoritative name server.

Does this work for internal/intranet domains?

No. The query goes through Toova to Google Public DNS, which only sees records published on the public internet. Internal split-horizon DNS is invisible.

How reliable is the resolver?

Toova resolves through Google Public DNS from its own same-origin API. This avoids browser CORS issues and keeps the tool independent from third-party browser DoH behavior.

DNS Lookup — A, AAAA, MX, TXT records via DoH

DNS Lookup over DoH

Private by design — runs entirely in your browser

Type a hostname like google.com, pick A, AAAA, MX, TXT, NS, or CNAME, and Toova resolves it through Google Public DNS via a same-origin API.

Why DNS-over-HTTPS

DNS-over-HTTPS wraps DNS queries inside HTTPS. Toova calls a same-origin API backed by Google Public DNS, so the static browser app does not depend on third-party DoH CORS behavior.

Record types in plain English

A maps to an IPv4 address; AAAA maps to an IPv6 address. MX lists the mail exchangers for the domain, ordered by preference. TXT carries arbitrary text — SPF, DKIM, DMARC, domain verification tokens all live in TXT. NS lists the authoritative name servers for the zone. CNAME is an alias from one hostname to another. The TTL column shows how long resolvers may cache the answer.

What we do not see

Your browser sends the DNS name and record type to Toova. Toova forwards only that DNS question to Google Public DNS; no personal data is needed for the lookup.
