What ASPA Providers Mean

ASPA (Autonomous System Provider Authorization) is an RPKI object that lists which upstream providers an ASN authorizes.

These ASNs are allowed upstreams for the customer ASN.
Not a guarantee that the relationship is active right now.
Helpful for validation of provider relationships and path checks.

In short: the listed providers are authorized to carry this ASN as a customer.

What is Geofeed?

Geofeed (RFC 8805) lets network operators publish authoritative geolocation data for their IP prefixes in a simple CSV file.

Why it matters

Accurate geolocation — commercial geo-IP databases often mislocate prefixes. A geofeed gives you direct control over what location is reported.
Faster corrections — instead of filing tickets with every geo-IP vendor, publish once and major providers (Google, Cloudflare, MaxMind, etc.) pick it up automatically.
Content delivery — CDNs use geolocation to route traffic; wrong location means suboptimal routing and higher latency for your users.
Regulatory compliance — some content is geo-restricted; incorrect geolocation can block your users or expose you to compliance issues.

How to set it up

Create a CSV file with your prefix geolocation data (one line per prefix):

192.0.2.0/24,US,US-CA,Los Angeles,90001
2001:db8::/32,DE,DE-BE,Berlin,10115

Host the file on a web server over HTTPS (e.g. https://example.com/geo/geofeed.csv).

Add a geofeed: attribute to your inetnum/inet6num RPSL object at your RIR:

remarks:        Geofeed https://example.com/geo/geofeed.csv
geofeed:        https://example.com/geo/geofeed.csv

Optionally, sign your geofeed with RPKI (RFC 9632) for stronger authentication.

Once published, geo-IP providers and tools like this one will automatically discover and use your geofeed data.

AS-SET Search Help

You can search by different input types:

AS-SET name (e.g. AS-GOOGLE) — exact lookup showing members, child sets, and parent sets.
ASN (e.g. 15169 or AS15169) — find all AS-SETs this ASN is a member of.
IP address (e.g. 8.8.8.8 or 2001:4860::1) — finds the origin ASN via BGP, then shows its AS-SET memberships.

Partial match checkbox enables substring search across all AS-SET names (e.g. searching GOOGLE finds AS-GOOGLE, AS-GOOGLE-CLOUD, etc.).
