About Net Utils
Net Utils is a practical suite of online network diagnostics tools for DNS, IP, email, HTTP, SSL, ports, ping, MTR and traceroute checks.
Reliable diagnostics without noise
The service is designed to make infrastructure checks understandable: from a single DNS record to global connectivity tests powered by distributed probes.
Network and domains
Check DNS records, propagation, reverse DNS, WHOIS and route availability in one place.
Security checks
Review SSL certificates, HTTP responses, mail authentication records and IP reputation signals.
Performance insight
Measure ping, latency, packet loss, HTTP timing and browser speed without installing tools.
What Net Utils is built for
Net Utils focuses on everyday operational questions: why a domain does not resolve, why mail goes to spam, why a server is unreachable, why a region sees slow responses, or whether an exposed port is expected.
The interface is intentionally direct: enter a target, run the check, then read structured results with context and next steps.

Data sources
Live DNS lookups, TLS handshakes, HTTP requests, Globalping measurements, DNSBL checks and local server-side diagnostics are used where appropriate.
Quality and updates
Checks, labels and recommendations are refined as standards and real operational cases change. Results are designed to be transparent rather than mysterious.
Responsible use
Network tests and port scans should be run only for systems you own or have permission to inspect. The service uses rate limits to reduce abuse.
Principles
Results should explain what happened and why it matters.
Inputs are handled carefully and unnecessary long-term storage is avoided.
Tools are built around real troubleshooting workflows.
