DNS Lookup
Frequently Asked Questions about DNS Lookup
Which DNS record types does this tool retrieve?
The tool queries all primary DNS resource records: A (IPv4), AAAA (IPv6), MX (mail exchange), CNAME (canonical name), TXT (SPF, DKIM, DMARC, verification tokens), NS (name servers), SOA (start of authority), and CAA records.
How do DNS errors impact SEO and search indexing?
DNS resolution failures prevent search engine crawlers (Googlebot, Bingbot) from reaching your site. Repeated DNS errors can lead to crawl budget exhaustion and temporary de-indexing of key pages.
How long does DNS propagation take?
Propagation duration depends on the TTL (Time to Live) values configured on the records, typically ranging from 5-15 minutes up to 24-48 hours across global recursive resolvers.
What are CAA and TXT records used for?
CAA records specify which Certificate Authorities are allowed to issue SSL certificates for your domain. TXT records store machine-readable data for domain verification and email authentication protocols (SPF, DMARC).
Can I perform bulk DNS lookups for multiple domains?
Yes, bulk mode allows you to query DNS configurations for up to 100 domains simultaneously and export complete records in CSV format.
The Domain Name System translates human-readable domain names into the technical records used by browsers, mail servers, and other internet services. Incorrect or outdated DNS settings can make a website unavailable, break email delivery, prevent ownership verification, or send visitors to the wrong infrastructure. Reviewing DNS is therefore an important part of a technical website audit.
The DNS lookup retrieves common record types such as A, AAAA, CNAME, MX, TXT, NS, SOA, and CAA for the entered domain. Use the result to confirm an IP change, diagnose name-resolution problems, inspect mail routing, or check whether a verification record has propagated. Remember that cached records may remain visible until their TTL expires.
