remarks:        PA Space Aggregation
remarks:        =============
remarks:        GRNET aggregates its PA space before announcing it to its
remarks:        upstream(s) and exchanges. Should a custemer with PA space
remarks:        wishes not to have its prefexes aggregated, a special community
remarks:        should be used to tag this route (see below).
remarks:        
remarks:        Primary/Backup control
remarks:        ========================
remarks:        GRNET respects the MED received by its customers; thus, the
remarks:        customers can indicate their primary/backup line and control
remarks:        incoming traffic by setting MED appropriatelly. Also, the
remarks:        customers may use the community 5408:110 to indicate their
remarks:        backup connection (lower local pref), but this method is
remarks:        recommended only for customers multihomed to another Greek ISP
remarks:        that use their connection with GRNET as backup.
remarks:        
remarks:        Anycast
remarks:        ========================
remarks:        GRNET does not follow any explicit policy for anycast services.
remarks:        Normal routing (and, thus, preference) applies to all anycast

Details

Autonomous System Numbers (ASNs) are assigned to entities such as Internet Service Providers and other large organizations that control blocks of IP addresses. This network page, and the organization field that's shown on the main IP address information page and also returned in the geolocation API are based on the ASN.

The ASN details will often correspond to the IP address owner, but for smaller organizations it may be that organization's parent, or their ISP.
