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 AS4780

24 peers

AS983 AS2497 AS4134 AS4657 AS6939 AS7481 AS7713 AS8220 AS8359 AS8966 AS10099 AS17639 AS23673 AS35280 AS49544 AS57304 AS132337 AS137409 AS140627 AS9304 AS24482 AS39120 AS55720 AS58453

AS4780 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 AS4780

6 upstreams

AS2914 AS3491 AS6453 AS9002 AS9505 AS9924

AS4780 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS4780 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS4780

58 downstreams

AS4780 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.
