The ultimate BGP data
exploration tool
Explore how any prefix or ASN is routed across the internet, both live and historically. BGPHorizon turns 24 global route collectors into fast, searchable answers for network operators, investigators, and security teams.
The prefix overview for 1.1.1.0/24: origin, RPKI and IRR status, activity over time, AS paths, and communities.
Instead of parsing raw MRT dumps or standing up your own collectors, you get the full global routing table, from RouteViews and RIPE RIS combined, indexed and query-ready in seconds. Search any ASN, prefix, or IP.
A more approachable BGP tool
BGP has a reputation for being hard to understand. A goal of this platform is to change that. Every chart and tool explains itself in plain language, with helpful tooltips and the kind of clean, consistent navigation you expect from a modern CTI platform. Whether you live in routing every day or you are trying to make sense of an incident for the first time, BGPHorizon is designed to make investigators' and network engineers' lives easier.
Plain-language captions and hover tooltips on every visual, telling you what it shows, why it matters, and examples of how to interpret the results.
Type an ASN, prefix, IP, or a field query. Or use the query language for advanced searches.
Enrichment from RPKI, IRR, RDAP, PeeringDB, and BGPHorizon detections is folded in, so you can quickly understand the context.
Complete, clean data
Origin and history, RPKI and IRR status, RDAP and PeeringDB, AS paths, communities, activity over time, and global reachability. For any prefix or ASN, over historical windows.
Upstream and downstream relationships
An inferred transit graph built from the observed paths. Upstream providers climb toward the Tier 1s, downstream ASNs are also shown, and you can weight each link by how much traffic really uses it based on observations.
Geo communities on a map
Operators tag their routes with geo-communities that say where traffic entered their network. BGPHorizon decodes those tags and plots them geographically. Click any city to see the exact communities observed there, who published them, and how often.
Hijacks, leaks, RPKI problems, and more
We watch the entire internet for 15 detection types, from RPKI-invalid origins and MOAS conflicts to path anomalies and withdrawals. When something fires, drill down to the raw BGP events behind it to see the evidence.
Monitor your networks or networks of interest
Monitors are fully customizable across all 15 detection types we watch the entire internet for. Track any prefix or ASN, tune exactly which signals you care about, and get alerts by email, webhook, Slack, or Discord the moment something changes.
Hunt through raw BGP events
Go beyond a single prefix or ASN. Query the raw BGP event stream with a field-based search language, matching on AS path, origin, communities, next hop, and more. Hunt for routes that transit a network, carry a specific community, or match a path signature across the entire table.
AI-ready
BGPHorizon is built to plug into your automation and your AI. A fast, documented REST API exposes 35 endpoints across everything the platform knows, and a Model Context Protocol server ships 19 task-shaped tools, plus reference resources and prompts, so any AI assistant can investigate routing in plain language. Hosted or self-hosted, it is ready for whatever your AI workflow needs.
