DNS Lookup
WEBLook up A, AAAA, MX, TXT, NS and CNAME DNS records for any domain — free in your browser.
What is the DNS Lookup tool?
DNS lookup resolves the DNS records behind any domain in seconds: A and AAAA (the IPv4 and IPv6 addresses a name points to), MX (which mail servers accept its email), TXT (verification, SPF and other text entries), NS (the authoritative name servers) and CNAME (aliases that point one name at another). Type a domain, pick a record type and read the answer — a free DNS checker with no sign-up and no rate-limit nag after your third query.
It covers the everyday jobs: check DNS records after moving a website, run an MX record lookup before switching email providers, confirm that the TXT record a service asked you to add actually resolves, or simply resolve a domain to its IP while debugging. Each answer shows the record value and its TTL, so you can tell how long old data may stay cached elsewhere. If a domain looks suspicious, pair this with Carbide's WHOIS lookup to see its registrar and age, or IP Info to inspect the address it points to.
One thing worth knowing: a DNS query has to leave your device by definition. The domain and record type you enter are sent over encrypted HTTPS (DNS-over-HTTPS) to a public resolver — the same kind of query your browser makes whenever it opens a site. Nothing else is sent, and Carbide does not store your queries. The page works just as well on a phone, in English and Arabic.
How to use the DNS Lookup
- Enter the domain you want to check — for example example.com, no https:// needed.
- Pick the record type: A, AAAA, MX, TXT, NS or CNAME.
- Run the lookup and read the records that come back, each with its value and TTL.
- Switch record types to see the domain's full DNS picture without retyping.
- Copy any value with a tap — useful when comparing against your registrar's panel.
Frequently asked questions
How do I check my DNS records?
Enter your domain above, then run the lookup once per record type you care about — A for the website address, MX for mail, TXT for verification entries, NS for name servers. The results show what the public DNS system is serving right now, which may differ from what you just saved at your registrar if the change is still propagating.
What is an MX record?
An MX (mail exchange) record tells the internet which servers accept email for a domain, with a priority number for each. If MX records are missing or point at the wrong provider, email to that domain bounces — checking them is the first step when mail stops arriving.
What is a TXT record used for?
TXT records hold free-form text that services read for verification and policy: proving domain ownership to Google or Microsoft, SPF entries that say which servers may send your email, and DKIM or DMARC policies that fight spoofing. A TXT lookup shows every entry currently published.
Why don't my DNS changes show up yet?
DNS answers are cached for the record's TTL (time to live) — often anywhere from five minutes to 48 hours. Until caches expire, different networks can see different answers. The TTL shown next to each record tells you the maximum wait; there is no way to force other resolvers to refresh sooner.
Is this the same as nslookup or dig?
It returns the same live answers, without a terminal. nslookup and dig are command-line tools that query DNS directly; this page sends the equivalent query over DNS-over-HTTPS and formats the response for reading on any device, including your phone. For scripted or advanced work (custom resolvers, DNSSEC debugging), dig is still the right tool.
Is this DNS checker free? Are there limits?
Yes — free, no account, no daily quota and no paid tier hiding record types. It is part of Carbide's free toolkit, so the networking tools around it (WHOIS lookup, IP info, ping, speed test) are free too.
What does a lookup send, and is it private?
Only the domain name and record type you enter, sent over encrypted HTTPS to a public DNS resolver — that query is simply how DNS works. Carbide does not log or store your lookups, and nothing about your connection is included beyond what any web request carries.
