PeerGlass

Fetch peering policy, IXP presence, NOC contacts, and BGP neighbours for an ASN.

Data sources (queried in parallel):

• PeeringDB (www.peeringdb.com) — the internet's peering registry

• RIPE Stat asn-neighbours — live BGP upstream/downstream relationships

Information returned:

• Peering policy: Open / Selective / Restrictive / No Peering

• IRR AS-SET (used in route filters, e.g. AS-CLOUDFLARE)

• NOC email, abuse email, peering contact email

• IXP presence: which exchange points, peering IPs, link speed

• BGP neighbours: up to 30 adjacent ASNs in the routing table

Use cases:

• "Does Cloudflare have an Open peering policy?"

• "Which IXPs is AS13335 present at?"

• "What is the NOC email for AS1234 to report an incident?"

• "Is this ASN a residential ISP or a CDN?"

Results are cached for 6 hours.

Args: params (PeeringInfoInput): - asn (str): ASN to look up (e.g. 'AS13335', '13335', 'AS-CLOUDFLARE') - response_format (str): 'markdown' (default) or 'json'

Returns: str: Peering policy table, IXP presence table, contacts, BGP neighbours.
