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 AS1600

0 peers

AS1600 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 AS1600

1 upstreams

AS1600 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS1600 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS1600

0 downstreams

AS1600 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.
