Check DNS records for any domain online. Use this free DNS checker to lookup A, AAAA, CNAME, MX, TXT, NS, SOA and CAA records and test DNS status quickly.
Use this DNS Checker to check DNS records for any domain and see how your website, email, and nameserver settings are resolving online. Enter a domain name, choose the DNS record type you want to test, and run a fast DNS lookup to view live results. This tool helps you check A, AAAA, CNAME, MX, TXT, NS, SOA, CAA, and PTR records without using command-line tools.
A DNS lookup is useful when a website is not opening, email is not working, nameservers have changed, or a new DNS record needs to be verified. Instead of guessing where the problem is, you can check DNS records online and confirm the current value, TTL, record status, and DNS response from the selected resolver or authoritative DNS server.
To use the DNS checker, enter your domain name in the search box, select the record type, and click the check button. You can test one record type, such as A, MX, TXT, CNAME, NS or SOA, or check all common DNS records when you want a complete view of the domain’s DNS setup. The result helps you see whether the domain is pointing to the right server, mail provider, verification record, or nameserver.
This DNS check online tool is built for website owners, developers, SEO users, hosting users, and anyone who needs a quick answer. You do not need to install software or remember nslookup commands. If you want to check my DNS, test a client domain, or confirm a DNS change after editing hosting settings, this DNS check tool gives a clear result in seconds.
DNS records control how a domain works. An A record points a domain to an IPv4 address, while an AAAA record points it to an IPv6 address. A CNAME record connects one hostname to another hostname, MX records handle email routing, TXT records are used for verification and email security, NS records show the nameservers, SOA records show zone authority details, and CAA records control which certificate authorities can issue SSL certificates for the domain.
This DNS records lookup helps you check DNS records for a domain before and after making changes. You can use it for an A record lookup when a website is pointing to the wrong IP, a CNAME lookup when a subdomain is not loading, a TXT record lookup when Google, Microsoft, SPF, DKIM or DMARC verification is failing, and an MX record lookup when emails are not being delivered correctly.
A DNS lookup result shows the record type, value, TTL, and response status for the domain you entered. The value is the actual answer returned by DNS, such as an IP address, mail server, text string, nameserver, alias, or authority record. TTL means “time to live,” and it tells DNS resolvers how long they can cache that record before asking again for a fresh result.
When you use a DNS lookup tool, the most important thing is not just whether a record exists, but whether it matches what you expected. A wrong A record can send visitors to the wrong server. A missing MX record can stop email delivery. A broken TXT record can fail domain verification. A wrong CNAME can break a subdomain. Reading the DNS lookup result carefully helps you find the exact issue faster.
A nameserver check shows which NS records are responsible for your domain. Nameservers are important because they tell the internet where your domain’s DNS zone is managed. If your domain is using old nameservers, wrong hosting nameservers, or mixed nameservers from different providers, DNS records may not resolve the way you expect.
Use the nameserver check when you change hosting, connect a domain to a new DNS provider, move DNS to Cloudflare, or update records at your registrar. A DNS server lookup can help confirm whether the domain is using the correct DNS provider and whether the authoritative DNS server is returning the right record values. This is often the first place to check when a domain does not load after a DNS change.
A DNS test online helps detect common problems that affect websites and email. If your site is not opening, check the A or AAAA record. If a subdomain is broken, check the CNAME record. If email is bouncing, check MX records and related TXT records. If domain verification is not working, check TXT records exactly as provided by the service. Small mistakes such as extra spaces, wrong hostnames, old IP addresses, or missing records can create large problems.
This DNS test also helps after changing hosting, adding SSL, setting up business email, connecting a domain to a website builder, or verifying a domain in Google Search Console. When a record is missing or different from what your provider gave you, the result tells you what needs to be fixed. That makes the tool useful for both quick checks and real troubleshooting.
DNS lookup and DNS propagation are related, but they are not the same. A DNS lookup checks what a DNS server returns right now for a domain or record type. DNS propagation is the process where updated records spread across different DNS resolvers and locations after a change. If you recently changed a record, one resolver may show the new value while another still shows the old value until its cache expires.
Use this DNS lookup page to check current DNS records, verify domain settings, or inspect record values. Use a DNS propagation checker when you want to compare the same record across multiple global locations. For best results, check the record value first with this DNS checker, then use a propagation tool if the record has changed recently and users in different regions are seeing different results.
