i am using traceroute command for checking internet path stability. i ran a tracroute and it gave something like the following:

Code:

Was this every time or did you try it once? I was able to resolve it to AS11164. Perhaps there was a timeout on the lookup, or maybe it's rate limited.

It means the ASN was not in the lookup table. The version of traceroute you are using uses third party lookups to do ASN to IP matching. For whatever reason the lookup failed / doesn't exist.

Traceroute cannot directly get the AS information since that is in the BGP routing core and the protocol normally doesn't need to provide that information to IP. They get the information by scanning certain BGP core routers that they have visibility in to.
