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 AS23520

16 peers

AS3303 AS3356 AS3816 AS6057 AS6939 AS7195 AS12956 AS14080 AS16735 AS18678 AS23473 AS27951 AS52320 AS53828 AS60068 AS199524

AS23520 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 AS23520

5 upstreams

AS174 AS1299 AS6762 AS6830 AS22356

AS23520 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS23520 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS23520

167 downstreams

AS23520 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.
