Frequently Asked Questions

What is the purpose of an MX record?
MX (Mail Exchanger) records specify which mail servers are responsible for accepting incoming email messages on behalf of your domain, alongside numerical priority rankings for fallback servers.
What are TXT records commonly used for today?
TXT records hold human- and machine-readable text used predominantly for domain ownership verification, SPF email authorization, DKIM cryptographic signatures, and DMARC security policies.
What is the difference between an A record and a CNAME record?
An A record maps a hostname directly to an IPv4 IP address (e.g. 192.0.2.1), whereas a CNAME record creates an alias pointing one domain name to another domain name.
Can this tool check subdomains as well as apex domains?
Yes. You can lookup root domains like example.com or specific subdomains like api.example.com, blog.example.com, or staging.example.com without restrictions.
Is my search history logged or shared with third parties?
No. OmegaTools processes DNS lookups transparently and ephemerally without logging queries or building tracking histories.
