DNS Lookup & Domain Analyzer

A DNS record is a database record residing on a DNS server that maps a domain to an IP address or specifies mail server routing (MX) or security settings (TXT, CAA).

This tool queries Cloudflare's public DNS-over-HTTPS (DoH) API. All lookups are performed directly in your browser using secure client-side fetch calls without tracking.

SPF and DMARC are DNS TXT records used to authenticate emails sent from your domain, preventing domain spoofing, phishing, and ensuring high email deliverability.

DNS resolution speed is the very first step in website load time (affecting Core Web Vitals like LCP). A slow DNS provider increases page load delay, leading to higher bounce rates and poorer search engine rankings. Switching to a fast DNS hosting provider directly boosts SEO performance.

TTL specifies how long DNS records are cached by ISP servers and browsers. During server migration, reducing the TTL values in advance ensures that visitors and search engine bots are redirected to the new server instantly without experiencing downtime or 404 errors, preserving organic search traffic.

Yes, properly configured SPF, DKIM, and DMARC TXT records prevent your domain name from being spoofed by bad actors, which significantly boosts your email sender reputation. This ensures your marketing campaigns land directly in user inboxes instead of spam folders, resulting in higher click-through traffic.

DNSSEC adds cryptographic signatures to your DNS records to prevent spoofing and DNS cache poisoning attacks. While not a direct ranking factor in Google's algorithm yet, it prevents malicious redirect attacks that can cause Google to de-index or penalize your website, making it essential for domain authority and traffic safety.
