BGP Route Lookup

Look up BGP routes for any IP address or network prefix. See origin ASN, RPKI validation, and MOAS detection with broad global routing visibility.

Global Visibility

BGP data from authoritative routing sources with broad global coverage

RPKI Validation

Every route checked against published ROAs - valid, invalid, or not found

MOAS Detection

Identify prefixes announced by multiple origin ASNs across collectors

Origin Verification

Cross-reference origin ASN against IRR route objects and RPKI ROAs

What You Get

Origin ASN and announcing organization
Broad route visibility from global vantage points
RPKI validation status (valid / invalid / not found)
IRR route object cross-reference
More-specific prefixes and covering aggregates
RIR allocation data and registration details

Frequently Asked Questions

What is a BGP looking glass?

A BGP looking glass lets you see how a prefix is routed on the Internet - which ASN originates it, whether the route is cryptographically validated via RPKI, and how it appears across multiple vantage points. Traditional looking glasses are hosted by individual carriers; ipctl aggregates data from authoritative routing sources for a broader view.

Where does the BGP data come from?

We process full routing table dumps from authoritative routing data sources. Data is updated regularly from the latest available snapshots, providing broad visibility into Internet routing.

What does RPKI status mean?

RPKI (Resource Public Key Infrastructure) lets prefix holders cryptographically authorize which ASN may originate their routes. 'Valid' means the origin matches a published ROA, 'invalid' means it doesn't (possible hijack), and 'not found' means no ROA exists for the prefix.

Can I query BGP routes via API?

Yes. The GET /v1/prefix/{prefix} endpoint returns BGP routes with origin ASN, RPKI status, and collector information. The GET /v1/ip/{ip} endpoint also includes BGP routes for the covering prefix. Free tier includes 1,000 requests/day.

Programmatic Access

Query BGP routes via the REST API. Returns all routes with origin ASN, RPKI status, and collector information.
