DNS Lookup for Websites

Website DNS controls how a domain reaches a server, CDN, or platform. A website-focused DNS lookup helps confirm the records that affect web routing, hostname aliases, and nameserver setup.

DNS records help control how websites, email, verification systems, and subdomains work.

DNS records used by websites

Websites commonly rely on A, AAAA, CNAME, and NS records. Each plays a role in routing users to the correct service or server.

When to check website DNS

Check website DNS when launching a site, changing hosting providers, connecting a domain to a builder, adding a CDN, or troubleshooting downtime.

What to review in results

The most important checks are whether the domain points to the right IP or hostname and whether nameservers are configured in the right place.

Common website DNS mistakes

Common mistakes include wrong A records, incorrect CNAME targets, stale old hosting values, and updating the DNS zone in the wrong provider dashboard.
