DNS Lookup
Look up DNS records for any domain using DNS-over-HTTPS. Check A, MX, TXT, CNAME, and more.
Maps domain to IPv4 address. Essential for website hosting.
Maps domain to IPv6 address. For IPv6-enabled servers.
Alias pointing to another domain. Used for subdomains and CDNs.
Mail server records. Required for receiving emails.
Text records for verification, SPF, DKIM, DMARC.
Nameserver records. Delegates DNS for the domain.
Start of Authority. Contains zone info and admin contact.
Reverse DNS lookup. Maps IP back to domain name.
Service records. Used for specific services like SIP, XMPP.
Certificate Authority Authorization. Controls SSL issuers.
DNS lookups are performed using DNS-over-HTTPS (DoH) via Cloudflare. Your queries are encrypted.
DNS Lookup Tool Online
Look up DNS records for any domain. Check A, AAAA, MX, TXT, CNAME, NS, and SOA records. Free online DNS checker using DNS-over-HTTPS.
How It Works
Enter a domain name and select the record type you want to query (A, AAAA, MX, TXT, CNAME, NS, SOA, etc.). Our tool uses DNS-over-HTTPS to fetch the records securely and displays all the results with TTL values.
Common Use Cases
- Checking if your domain's DNS records have propagated after making changes
- Verifying MX records to troubleshoot email delivery issues
- Looking up TXT records for SPF, DKIM, or domain verification
- Finding the nameservers (NS) for a domain
Frequently Asked Questions
DNS (Domain Name System) translates human-readable domain names (like google.com) into IP addresses (like 142.250.80.46) that computers use to communicate.
DNS-over-HTTPS (DoH) is a protocol that encrypts DNS queries, preventing eavesdropping and improving privacy compared to traditional DNS lookups.
DNS propagation can take anywhere from a few minutes to 48 hours. Different DNS servers around the world update at different rates.
MX (Mail Exchange) records specify the mail servers responsible for receiving email for a domain. They include a priority value — lower numbers are tried first.
A CNAME (Canonical Name) record creates an alias from one domain to another. For example, www.example.com → example.com. It cannot be used at the zone apex (root domain).
DNS changes typically propagate within 15 minutes to 48 hours. TTL (Time To Live) values on DNS records determine how long resolvers cache records before re-querying.
TXT records store text data for various purposes: SPF (email authentication), DKIM (email signing), domain verification (Google, Microsoft), and DMARC policies.
