Live network diagnostics

Network Tests Online for Speed, Ping, Jitter, DNS, IPv6 & More

Use focused browser-based checks to troubleshoot lag, unstable calls, DNS issues, IPv6 reachability, remote access problems, and certificate or protocol setup without installing anything.

1 Start with the test that matches your current problem.
2 Review the exact signal that matters, such as speed, latency, jitter, DNS records, IPv6 reachability, or open ports.
3 Save or share the result when you need help from your ISP, host, or IT team.

Choose the right network test for the problem

Start with the symptom you want to validate: slow speed, high latency, lag spikes, DNS issues, IPv6 reachability, remote access, certificates, or browser protocol behavior.

Internet Speed Test

Measure download, upload, latency, and connection quality before troubleshooting Wi-Fi, streaming, or ISP issues.

Run speed test

Ping Test

Check browser latency and missed samples when games, calls, or web apps feel delayed.

Run ping test

Jitter Test

Measure ping variation to spot lag spikes, unstable Wi-Fi, and choppy calls.

Run jitter test

Open Ports Test

Test whether a public TCP port is reachable for game servers, SSH, RDP, NAS, or port forwarding.

Run open ports test

IPv6 Test

Check whether your network reaches IPv6 services and whether dual-stack connectivity is working as expected.

Run IPv6 test

DNS Lookup

Resolve DNS records to validate propagation, mail routing, and domain configuration.

Run DNS lookup

WHOIS Lookup

Review registrar data, status, and nameservers when ownership or delegation is in question.

Run WHOIS lookup

SSL Certificate Checker

Check certificate expiry, issuer, SANs, and hostname match for a public HTTPS host.

Check SSL certificate

Security Headers Checker

Review CSP, HSTS, X-Frame-Options, Referrer-Policy, Permissions-Policy, COOP, and CORP for a public URL.

Check security headers

HTTP/2 + HTTP/3 Test

See whether your browser negotiates HTTP/2 or HTTP/3 with a site.

Run HTTP protocol test

WebRTC Leak Test

See whether your browser exposes local or public IP candidates through WebRTC.

Run WebRTC leak test

IP Address Lookup

See your public IP address, ISP, ASN, and basic connection details.

Check IP address

Built for clearer troubleshooting

Useful when you need to separate speed issues from latency, DNS, reachability, or browser-level configuration problems.

Troubleshoot by symptom

Start with the problem you actually see, such as lag spikes, failed remote access, SSL errors, or IPv6 reachability.

Separate speed from stability

Use speed, ping, and jitter together so bandwidth problems are not confused with latency variation or Wi-Fi instability.

Rerun after every change

Compare results after router changes, DNS updates, firewall rules, or switching between Wi-Fi, ethernet, and mobile data.
