Free DNS Lookup Tool – Check DNS Records

Find and inspect the DNS records configured for a domain with the
free JUJU Host DNS Lookup tool. Check A, AAAA, CNAME, MX, NS, TXT
and SOA records to troubleshoot domain configuration, website
connectivity and email delivery.

Enter a domain name in the lookup tool below to retrieve the DNS
information available through the resolver used by our server.

What Is a DNS Lookup?

DNS stands for Domain Name System. It is the system that translates
human-readable domain names, such as example.com, into information
that computers and network services use to locate websites and
other internet services.

A DNS lookup queries DNS information associated with a domain.
These records help browsers locate web servers, mail servers and
other services connected to a domain.

DNS lookups are useful when setting up a new website, moving hosting
providers, configuring email, changing nameservers or investigating
connection problems.

DNS Records You Can Check

A Record

An A record maps a domain name to an IPv4 address. It is commonly
used to direct a website domain to its hosting server.

AAAA Record

An AAAA record maps a domain name to an IPv6 address. It allows
compatible devices and networks to reach a server over IPv6.

CNAME Record

A CNAME record creates an alias from one domain name to another
canonical hostname. It is commonly used for subdomains and
third-party services.

MX Record

MX records identify the mail servers responsible for receiving
email for a domain. Their priority values help determine which
mail server should be preferred.

NS Record

NS records identify the authoritative nameservers for a domain.
They are important when configuring domain DNS hosting or changing
DNS providers.

TXT Record

TXT records store text-based DNS information. They are frequently
used for domain verification and email authentication systems
such as SPF, DKIM and DMARC.

SOA Record

The Start of Authority record contains administrative information
about a DNS zone, including its primary nameserver and zone
management parameters.

How to Use the JUJU Host DNS Lookup Tool

Enter the domain name you want to investigate.
Submit the domain using the lookup tool above.
Review the DNS records returned by the resolver.
Check the record values against your hosting or DNS provider’s
configuration.
If a record is missing or incorrect, review the DNS settings
with your domain or hosting provider before changing anything.

When Should You Perform a DNS Lookup?

Website migration: Check whether your domain
points to the intended hosting server.
Email configuration: Inspect MX and TXT records
when configuring mail services.
Nameserver changes: Review the nameservers
associated with a domain.
Website troubleshooting: Investigate DNS
configuration when a website cannot be reached.
Domain verification: Check TXT records used
by hosting, email and other online services.
Hosting setup: Verify DNS records after
connecting a domain to a new server.

DNS Lookup vs. DNS Propagation Checker

A DNS lookup displays records returned by the DNS resolver used
for the query. A DNS propagation checker is different: it compares
DNS responses from multiple resolvers or locations to help identify
differences after DNS changes.

The JUJU Host DNS Lookup tool checks records through its server’s
configured resolver. Results can differ from those returned by
other DNS providers because of caching, resolver configuration
and DNS propagation.

Frequently Asked Questions

Is the JUJU Host DNS Lookup tool free?

Yes. The tool is provided as a free resource for checking supported
DNS records for a domain.

Which DNS record types are supported?

The tool supports A, AAAA, CNAME, MX, NS, TXT and SOA records.

Why do DNS lookup results sometimes differ?

DNS responses may differ because of resolver caching, DNS
propagation, geographic location and the configuration of
individual DNS providers.

Can a DNS lookup fix my domain configuration?

No. A lookup displays DNS information but does not change your
domain settings. You must update records through your domain
registrar or DNS hosting provider.

Does an MX record control outgoing email?

MX records identify the servers that receive incoming email.
Outgoing email delivery also depends on your mail server and
appropriate authentication and sending configuration.

Does this tool check DNS globally?

No. It queries the resolver configured on the JUJU Host server.
It is not a worldwide DNS propagation testing service.
