Subject: [routing-wg] Best source for historical RADB AS-SET data

 

Hi RIPE Routing-WG,
Does anyone know of an easy way to determine *when* a particular ASN was first added to a specific AS-SET in RADB?

More specifically, I am looking for a historical source (besides downloading the entire list of snapshots from ftp.radb.net and comparing) or tool that would allow me to identify the earliest date on which a given ASN appeared as a member of an AS-SET.

Thanks in advance for any suggestions.

Best regards,

Salvador Bertenbreiter
