DNS Check
Ensures your domain name resolves correctly to an IP address, detecting DNS misconfigurations and propagation issues.
What is DNS?
The Domain Name System (DNS) is often described as the internet's phone book. It is a hierarchical, distributed database that translates human-readable domain names (like example.com) into machine-readable IP addresses (like 93.184.216.34) that routers and servers use to direct traffic.
DNS was originally specified in RFC 1034 and RFC 1035. Every time you visit a website, your device queries a DNS resolver which walks the hierarchy — from root servers, to TLD servers, to authoritative nameservers — to find the answer.
What is a DNS Check?
A DNS check verifies that your domain resolves correctly to a valid IP address. It queries an authoritative nameserver directly, independent of your web server, so it catches DNS-level failures that other checks would miss.
What DigiPulse Checks
Domain resolution — Confirms your domain resolves to a valid IP address.
Response time — Measures how fast DNS lookup completes.
Failure detection — Alerts you if the domain becomes unresolvable.
Why It Matters
DNS failures mean no one can reach your site, even if your server is perfectly healthy. Issues can arise from expired domains, misconfigured records, or DNS provider outages. This check catches those problems independently of your web server.
