Which DNS server does the lookup use?

DNS Lookup uses DNS over HTTPS (DoH) to query a public resolver. This means the query is encrypted and doesn't go through your ISP's DNS, which can be useful when diagnosing whether a propagation issue is local to your ISP.

Why is my newly updated DNS record not showing yet?

DNS changes take time to propagate across the internet based on the record's TTL value. If the TTL was set to 3600 (one hour), resolvers that cached the old value won't refresh for up to an hour. Lowering the TTL before making changes speeds this up.

Can I look up records for any domain, including ones I don't own?

Yes — DNS is public by design. You can query records for any domain. This is how DNS resolvers around the world work.

What does a TXT record contain and why would I check it?

TXT records store arbitrary text data. They're most commonly used for SPF records (which IPs are allowed to send email for a domain), DKIM public keys, Google and Microsoft domain verification tokens, and DMARC policies.

What it does

DNS Lookup lets you query the Domain Name System for any domain and see the exact records it returns — A (IPv4 addresses), AAAA (IPv6 addresses), MX (mail servers), TXT (verification and policy records), NS (name servers), and CNAME (canonical name aliases). It's the tool developers and sysadmins reach for when checking whether a DNS change has propagated, verifying SPF or DKIM records for email deliverability, or diagnosing why a site isn't resolving. The lookup runs directly in your browser using DNS over HTTPS, so no software installation is needed. It's completely free and requires no account. Results show the raw record data and TTL values so you can see exactly what the DNS is serving right now.

How to use the DNS Lookup

Open DNS Lookup in Carbide and type the domain name you want to query (for example, example.com).
Select the record type you need: A, AAAA, MX, TXT, NS, or CNAME.
Tap Look up to run the query.
Read the returned records, including the record value and TTL (time to live in seconds).
Switch to a different record type and look up again if you need to check multiple record types for the same domain.
