AS1000

AS12257 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 AS12257

14 upstreams

AS701 AS1273 AS2686 AS3356 AS4657 AS4755 AS5400 AS7018 AS7473 AS8220 AS9498 AS12400 AS12849 AS198949

AS12257 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS12257 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS12257

0 downstreams

AS12257 has no downstreams recorded.

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.
