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 AS20746

0 peers

AS20746 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 AS20746

2 upstreams

AS3269 AS6762

AS20746 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS20746 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS20746

10 downstreams

AS9076 AS15472 AS20580 AS29270 AS35793 AS44920 AS54253 AS60049 AS207157 AS209071

AS20746 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.
