CNAME, MX and NS records describe aliases, email delivery and authoritative nameservers.

FAQ
DNS lookup questions
What is a DNS lookup?+
A DNS lookup asks a resolver for the public records associated with a domain. Those records can identify website addresses, mail servers, nameservers and domain policies.
Why can a DNS change take time to appear?+
Resolvers may cache a record for its TTL. Until that cache expires, different users or resolvers can temporarily receive different answers.
Does this tool continuously monitor DNS?+
No. This page performs an on-demand lookup. Continuous DNS monitoring is planned for OwlUptime and is marked as coming soon.
Is the result authoritative?+
The result shows the answer returned by a public recursive resolver. For a configuration dispute, compare it with the authoritative nameserver and your DNS provider.
