What's New?

Country code flags for ASNs

• ASN overview pages and search results now display country flag icons based on RIR delegation data, making it easy to identify the registered country for any AS at a glance.

Smarter free-text search ordering

• Free-text search results are now ranked by match relevance. Matches on name fields (AS name, maintainer name, set name, NIC handle) appear first, followed by description matches, then other fields, with remarks last.
• Previously, results for a free-text query appeared in no particular order. Now, searching for something like “Cloudflare” will surface the AS-name match at the top instead of buried among description or remarks hits.

New API endpoint: BGP events export

• A new GET /api/v1/events/export endpoint lets you programmatically export up to 2 million BGP events (announcements and withdrawals) for any prefix or ASN.
• Responses are streamed as gzip-compressed NDJSON (newline-delimited JSON), so exports stay fast and memory-efficient even at high volumes.
• Requires API key authentication. See the API documentation for full details and examples.

Overview page full-export button

• Prefix and ASN overview pages now have an export button that downloads a consolidated snapshot of the resource, including PeeringDB data, IRR/RADB records, and high-level statistics (prefix counts, announcement and withdrawal totals, origin ASNs, and more).

BGPSentinel is now BGPHorizon!

• We’ve rebranded from BGPSentinel to BGPHorizon — same platform, new name and identity.

New logo

• Fresh branding with a new BGPHorizon logo across the entire platform, including a proper favicon.

Support/Feedback email address

• Have questions or feedback? Reach us at [email protected].

RDAP lookup data

• ASN and prefix overview pages now display RDAP (Registration Data Access Protocol) information including registration details, abuse contacts, and network metadata.

PeeringDB data & searchability

• PeeringDB facility, exchange, and network data is now integrated into overview pages and is searchable from the main search bar.

Additional IRR data sources

• Expanded IRR coverage to include RIPE, ARIN, APNIC, AFRINIC, Level3, NTTCOM, JPIRR, ALTDB, CANARIE, and Bell Canada alongside RADB.

IRR data moved to standalone tab

• IRR/RADB data now has its own dedicated tab on prefix and ASN overview pages for clearer navigation.

Open registration & guest access

• Anyone can now register for a BGP Horizon account with email verification.
• Guest access is available with up to 10 queries per day — no account required.

Email support & MFA

• Email verification for new accounts, password reset via email, and email-based multi-factor authentication are now supported.
• MFA can be enabled from the user panel under Profile → Security.

Optimized search capabilities — extremely fast event searching is now possible.

• A new query planner picks the most selective field in your query as the search “driver,” then narrows the event scan to just the prefixes that match — instead of walking the full events table.
• Backed by precomputed lookup tables (community ↔ prefix, AS-path ↔ prefix, peer-ASN ↔ prefix, origin-ASN ↔ prefix), the following event-search fields are now dramatically faster:
  • peer_asn — e.g. peer_asn: 13335
  • origin_asn — e.g. origin_asn: 13335
  • as_in_path — e.g. as_in_path: 3356
  • community, community_asn, community_action — e.g. community: "2914:420", community_asn: 2914, community_action: 666
  • collector_id — e.g. collector_id: rrc00
  • prefix — e.g. prefix: 8.8.8.0/24
• Combining these fields with AND automatically picks the smaller candidate set as the driver; OR unions the candidates, with a short-circuit fallback when one branch alone would be huge.
• Pair this with the new Search Query Guide for the full syntax reference.
