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 AS7474

10 peers

AS286 AS3356 AS4648 AS16509 AS24516 AS136557 AS137409 AS8075 AS13335 AS38561

AS7474 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 AS7474

4 upstreams

AS1221 AS2764 AS3257 AS7473

AS7474 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS7474 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS7474

187 downstreams

AS7474 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.
