Precision Network Diagnostics & Telemetry
Execute multi-region latency, hop route tracing, DNS resolution, and HTTP audits across 240+ global probes without local software.
Network Telemetry Engines
ICMP Ping Test
Measures millisecond round-trip latency, jitter, and packet loss across multiple geographical regions.
Network Traceroute
Traces packet progression hop by hop with per-router timing to pinpoint transit bottleneck nodes.
MTR Path Quality
Combines traceroute and continuous ping to correlate packet loss percentage against autonomous systems.
DNS Resolution
Validates record propagation (A, AAAA, CNAME, MX, TXT, NS, SOA) across regional recursive resolvers.
HTTP Reachability
Evaluates status codes, TTFB (Time to First Byte), DNS latency, and request transfer timelines.
IP Intelligence & ASN
Extracts autonomous system number (ASN), routing organization, reverse ISP, and geographic coordinates.
Security Headers Audit
Analyzes HTTPS protection headers including HSTS, CSP, X-Frame-Options, and Referrer-Policy with score rating.

Machine-Readable Network API
Every diagnostic tool on RTT.ICU is backed by high-throughput REST and markdown negotiation endpoints. AI agents, autonomous LLM tools, and SRE scripts can programmatically dispatch global measurements without browser dependencies.
REST JSON Endpoints
POST to /api/measurements for asynchronous global telemetry polling with 202 Accepted.
Markdown Negotiation
Send Accept: text/markdown to receive clean, LLM-ready markdown summaries directly.
