Routing intelligence tool
Prefix lookup for CIDR ranges, origin ASN context, registry data, BGP fixture hints, RPKI, IRR, and source-labeled warnings.
Normalize the prefix and show the address family and prefix length.
Connect the range to BGP, RDAP, RPKI, and IRR hints when public sources return data.
Responses keep source names, cache state, freshness, and partial-result warnings visible.
The lookup accepts IPv4 and IPv6 CIDR notation, then returns a structured result suitable for humans and scripts.
/api/lookup?query=1.1.1.0/24 returns structured JSON.A prefix lookup checks an IP network written in CIDR notation and returns registry, route, and source-labeled routing context when available.
CIDR notation combines a network address and prefix length, such as 1.1.1.0/24, to describe a range of IP addresses.
Yes. Prefix results can include RPKI and IRR status when those public sources return data.
