About This DNS Lookup Tool

DNS (Domain Name System) records translate domain names into IP addresses and control how email, websites, and other internet services work for a domain. Our free DNS lookup tool queries Google's public DNS API to retrieve current DNS records for any domain.

A records point the domain to an IPv4 address. MX records specify mail servers. TXT records contain SPF, DKIM, and verification codes. NS records show which nameservers control the domain's DNS. CNAME records create domain aliases. Use this tool to troubleshoot email issues, verify domain configuration, and check DNS propagation.

Frequently Asked Questions

An A (Address) record maps a domain name to an IPv4 address. For example, example.com → 93.184.216.34. This is the most fundamental DNS record that tells browsers where to find the website's server.

MX (Mail Exchanger) records specify which mail servers accept email for a domain. When someone sends email to user@example.com, the MX record tells the sending server where to deliver it. Multiple MX records can exist with different priorities.

TTL (Time To Live) is the number of seconds a DNS record is cached by resolvers before being re-fetched. A low TTL (300 seconds) means changes propagate faster. A high TTL (86400 = 24 hours) means fewer DNS queries but slower propagation of changes.

DNS propagation typically takes 24–48 hours for changes to reach all DNS servers worldwide, though it often happens much faster (within a few hours). The TTL of the old record determines the minimum propagation time.
