What is a DNS lookup?

A DNS lookup queries DNS servers to retrieve records associated with a domain name — such as where the website points (A/AAAA), where mail goes (MX), or verification text (TXT).

How do I check DNS records?

Enter your domain in the DNS lookup tool at the top of this page, run the query, and review grouped results. Use our DNS propagation checker if you need to compare resolvers worldwide.

What is an MX record?

An MX record tells email servers where to deliver messages for your domain. Each MX entry includes a priority number — lower numbers are tried first.

What is DNS propagation?

DNS propagation is the time required for DNS changes to update across recursive resolvers and ISPs worldwide. Until caches expire, some users may still see old records.

How long does DNS propagation take?

Typically between a few minutes and 48 hours, depending on TTL settings, record type, and how aggressively resolvers cache your zone.

What is a CNAME record?

A CNAME record aliases one hostname to another domain name. It cannot coexist with other records on the same name in most setups — use A/AAAA for root domains when your host requires it.

DNSSEC adds cryptographic signatures to DNS responses to help protect against spoofing and cache poisoning. It does not encrypt DNS traffic by itself — pair with DNS-over-HTTPS/TLS for privacy.
