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 AS4713

20 peers

AS4673 AS2000 AS2500 AS2514 AS2516 AS2518 AS2527 AS2687 AS2906 AS4777 AS7500 AS9374 AS16509 AS17534 AS17676 AS18126 AS18260 AS24262 AS25152 AS15169

AS4713 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 AS4713

2 upstreams

AS2497 AS2914

AS4713 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS4713 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS4713

104 downstreams

AS4713 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.
