| Applications can already map IPs to ASNs using information from a BGP | Looking Glass.

This sounds rather vague to me ... which protocol do I have to use for download from which address? Which file format is it, i.e., what kind of parser do I need? As your protocol proposal is based on HTTP anyway why not just always offer the file for download from the ALTO server? | Alternatively, the GetNetworkMap interface defined in this document | could be extended to map ASNs into a set of IP prefixes. The | mappings provided by the ISP would be both smaller and more | authoritative. This option sounds better to me.
