PeerGlass

Check whether a prefix or ASN is currently visible in the global BGP routing table.

Uses RIPE Stat (which aggregates data from RIPE RIS route collectors worldwide). BGP is the internet's routing protocol — the "GPS" that tells traffic how to navigate from one network to another.

For a prefix, returns:

• Whether it is currently announced in BGP

• Which ASN(s) are announcing it (multiple = potential hijack)

• Percentage of global BGP peers that can see it (visibility)

For an ASN, returns:

• Whether the ASN has any active BGP announcements

• A list of all announced prefixes (use rir_get_announced_prefixes for details)

Combine with rir_check_rpki for complete routing security assessment. Results are cached for 5 minutes (BGP tables change frequently).

Args: params (BGPStatusInput): - resource (str): Prefix (e.g. '1.1.1.0/24') or ASN (e.g. 'AS15169') - response_format (str): 'markdown' (default) or 'json'

Returns: str: BGP visibility, announcing ASNs, and prefix list. JSON schema: { "resource": str, "resource_type": str, "is_announced": bool, "announcing_asns": [str], "visibility_percent": float, "announced_prefixes": [{"prefix": str, "peers_seeing": int}] }
