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.
Websites commonly rely on A, AAAA, CNAME, and NS records. Each plays a role in routing users to the correct service or server.
Check website DNS when launching a site, changing hosting providers, connecting a domain to a builder, adding a CDN, or troubleshooting downtime.
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 mistakes include wrong A records, incorrect CNAME targets, stale old hosting values, and updating the DNS zone in the wrong provider dashboard.
