IP ranges are the different blocks of IP addresses advertised by an Autonomous System (AS). These ranges can be used by the same organization operating the AS, or by different organizations.

Peers of AS8047

23 peers

AS3130 AS3701 AS4181 AS1828 AS4766 AS4826 AS6327 AS6939 AS7575 AS11164 AS20055 AS34927 AS35280 AS40271 AS49544 AS53828 AS137409 AS199524 AS394256 AS9002 AS18106 AS24482 AS58511

AS8047 peers with these other Autonomous Systems.

Peering is a direct, often free, traffic exchange between Autonomous Systems (ASNs). They share routes only to their own networks and customers, making connections faster and cheaper for that specific traffic, without providing full internet access to each other.

Upstreams of AS8047

4 upstreams

AS2914 AS7922 AS11404 AS52025

AS8047 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS8047 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS8047

25 downstreams

AS5062 AS10538 AS13150 AS14789 AS15269 AS18443 AS21528 AS22079 AS22284 AS27575 AS33168 AS33707 AS33751 AS36056 AS40094 AS53469 AS62680 AS396006 AS397082 AS397349 AS397388 AS397548 AS397824 AS397967 AS398361

AS8047 provides internet connectivity to these downstream Autonomous Systems.

A downstream is a customer Autonomous System that pays another AS (its provider) for internet access. The provider AS carries the downstream's traffic and makes its network reachable.
