IXs themselves do not have ASNs, as they are Layer 2 providers.
most modern IXPs will have an ASN for their route server, and possibly a
separate asn for their mgmt infrastructure.
Not sure how useful the mgmt ASN is, although most IXPs will paradoxically
include this on their list of members.

Thanks for your help!
I studied all the AS-Path in the routing table (from routeviews and
RIPE), and found that some ASN of IXPs were included in some AS-Path. I
think that under normal circumstances they should not appear in the
AS-Path, hence i want to filter out them.
Best!
