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 AS109

3 peers
AS5713 AS8220 AS11164

AS109 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 AS109

17 upstreams
AS701 AS1221 AS1299 AS1680 AS2764 AS3356 AS3491 AS4637 AS4657 AS4755 AS4812 AS6939 AS7018 AS7473 AS8551 AS9498 AS17621

AS109 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS109 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS109

0 downstreams

AS109 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.
