Network & Routing Report
The full picture of how a network is put together and reaches the internet. Give it a network or address block and get a health card: what it announces, who it peers and buys transit from, whether it leans dangerously on a single upstream, and how well its routes are protected. The one-look report for network engineers assessing reach and resilience.
How it uses the graph
Traverses the BGP, RPKI, physical layers of the graph, in 10 steps:
Reading the prefix's MOAS, anycast and withdrawn flags…
Listing ASNs that also announce this prefix…
Reading the prefix's RIR allocation…
Listing prefixes the ASN's ROAs authorise…
Listing the ASN's announced prefixes…
Listing the ASN's facilities and exchanges…
Reading the ASN's rank, cone size and tags…
ASN identity & registration…
Prefix membership hierarchy…
AS-SET membership (IRR)…
Why each step runs
- 01BGP status. Establishes the prefix's baseline BGP state — the headline of the health card the rest of the run fills in.
- 02MOAS conflicts. Enumerates the CONFLICTS_WITH origins behind a MOAS, the concrete competing announcements that signal a hijack or misconfig.
- 03RIR allocation. Names which registry allocated the block, the authority record against which legitimacy is checked.
- 04RPKI ROA coverage. Walks ROA_AUTHORIZES_ORIGIN/PREFIX to show what the network is RPKI-authorised to announce — the basis for valid-vs-invalid routing.
- 05Announced prefixes. Enumerates what the network actually routes via ROUTES, the footprint compared against its ROA coverage.
- 06Facilities & IXes. Maps physical presence via AS_PRESENT_AT and IX_MEMBER, the interconnection context behind the routing posture.
- 07ASN reputation. Surfaces transit importance (AS-rank, customer cone) and bgp.tools tags — the reputation read that frames the whole health card.
- 08ASN identity & registration. Names the network, its home country, the organization that holds the AS number, and how many prefixes it announces — the identity header of the routing card.
- 09Prefix membership hierarchy. Lists the sub-prefixes and individual IPs nested inside the prefix, so you can see exactly what address space lives under the block.
- 10AS-SET membership (IRR). Shows which IRR-declared AS-SET the network belongs to and its member ASNs, the routing-policy grouping used by transit providers to build filters.
