Internet Exchanges

Exchanges where this network has a listed peering LAN connection

No Internet Exchange memberships found

The exchange directory has no current membership records for this AS.

Source:peeringdb retrieved

Exchange membership means the network has a listed connection; it does not prove peering with other members.

Observed adjacencies

Networks seen next to AS3 in BGP paths by route collectors.

Note:
These are observed adjacencies derived from BGP path data, not confirmed commercial relationships. A network appearing before another in an AS path does not establish that it is a paying transit customer, a settlement free peer, or anything else contractual. Adjacencies marked uncertain were seen only as direct peers of a route collector, so the collector's own peering may have created them.
