This table only shows the first 100 of the set of IPv4 and IPv6 prefixes. All data is available via our IP data API.

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 AS5371

0 peers

AS5371 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 AS5371

1 upstreams

AS27064

AS5371 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS5371 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS5371

0 downstreams

AS5371 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.
