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 AS27065

0 peers

AS27065 has no peers recorded.

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 AS27065

1 upstreams

AS721

AS27065 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS27065 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS27065

23 downstreams

AS56 AS126 AS149 AS321 AS367 AS463 AS467 AS637 AS656 AS1553 AS1733 AS2633 AS5052 AS5180 AS5231 AS5839 AS5927 AS5972 AS6035 AS27046 AS27064 AS27139 AS27153

AS27065 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.
