How It Works

CTX ASN Monitor uses only public Internet data sources — no access to your routers, no credentials, no agents. Just enter an ASN number and we query RIPEstat, PeeringDB, Cloudflare RPKI validators, and IRR registries to build a complete health profile.

01 — RPKI Validation

Checks ROA coverage for every announced prefix. Detects invalid or missing ROAs.

02 — IRR Consistency

Verifies route objects exist in Internet Routing Registries for proper filtering.

03 — Peer Diversity

Analyzes upstream providers to identify single points of failure in connectivity.

04 — Best Practices

Scores PeeringDB presence, IPv6 readiness, and WHOIS freshness against industry standards.
