Note: Full DNS lookups require a backend server (browser DNS APIs are not publicly available). This tool explains DNS record types and parses your domain. For live DNS lookups, use tools like MXToolbox or Google's DNS checker.

How to Use DNS Lookup

  1. 1

    Enter the domain name

    Type the domain you want to query — for example example.com — without http:// or www.

  2. 2

    Select the record type

    Choose from A, AAAA, MX, CNAME, TXT, NS, or SOA depending on which DNS records you need to inspect.

  3. 3

    View the live results

    See the DNS records returned by the resolver in real time, including TTL values and record data, to diagnose propagation or configuration issues.

Frequently Asked Questions

What is the difference between an A record and a CNAME record?
An A record maps a domain directly to an IPv4 address. A CNAME is an alias that points one domain name to another domain name, which is then resolved to an IP.
How long does DNS propagation take?
DNS changes can take anywhere from a few minutes to 48 hours to propagate globally, depending on the TTL set on the previous record and how aggressively resolvers cache responses.
Why would I look up TXT records?
TXT records are used to store SPF, DKIM, and DMARC policies for email authentication, as well as domain verification tokens for services like Google and GitHub.

About DNS Lookup

The DNS Lookup tool on Utilko lets you query live DNS records for any domain directly from your browser. Whether you are debugging email delivery failures, verifying that a new DNS record has propagated, or auditing a domain's security posture, this tool surfaces the exact record data returned by a public resolver.

Support for all major record types — A, AAAA, MX, CNAME, TXT, NS, and SOA — means you can investigate any DNS scenario without leaving your browser or reaching for command-line tools like dig or nslookup.
