How to read a DNS lookup

DNS records explain how a domain connects to websites, mail services and other systems. A lookup is useful after a domain change, when a website points somewhere unexpected or when email records need checking.

Start with these steps

  1. Enter a domain such as example.com. A full website URL is accepted, but the domain is the part used for the lookup.
  2. Select all supported record types for an overview, or choose one type to narrow the result.
  3. Compare the name, type and value with the settings supplied by your hosting or email provider. On a phone, scroll the record table sideways to see all columns.

The records you will see

A and AAAA · website addresses
A records contain IPv4 addresses; AAAA records contain IPv6 addresses. More than one address can be intentional.
CNAME · an alias
Points one hostname to another. A lookup may also show the address records associated with that name.
MX · mail server routing
Lists servers that receive mail for the domain. Lower priority numbers are preferred. A null MX record declares that the domain does not accept email.
TXT · text-based settings
Can contain provider verification, SPF or other domain settings. A TXT record’s existence alone does not confirm that every related service is configured correctly.
NS · authoritative nameservers
Identifies the nameservers responsible for the domain’s DNS zone. Compare these with the provider managing your records.
TTL · cache lifetime
Shown in seconds. Cached answers can remain visible while a DNS change is spreading between resolvers.

What to try next

For a website problem, follow the lookup with the website status tool. For mail configuration, use the email DNS checker. If a recent change has not appeared, check the active DNS provider and allow the existing cache to expire.

Know the limits

NetLuma uses its hosting server’s DNS resolver. A missing record can be intentional, and a different resolver may show a different cached answer. This lookup does not automatically edit your DNS.

GOOD TO KNOW

A little more context.

Why are my new records not showing?+

DNS responses are cached. Different resolvers can show older records until their cache expires. This tool uses the resolver available to the hosting server.

Which DNS records can I check?+

A, AAAA, MX, TXT, NS and CNAME. Choose one type to narrow the results, or select all supported types.
