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 AS9848

14 peers

AS9002 AS5580 AS6939 AS7713 AS8966 AS10099 AS14537 AS35280 AS49544 AS63927 AS132337 AS137409 AS24482 AS59318

AS9848 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 AS9848

10 upstreams

AS3491 AS4637 AS4766 AS6453 AS9318 AS9957 AS15412 AS23764 AS58453 AS138195

AS9848 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS9848 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS9848

53 downstreams

AS3608 AS4664 AS4670 AS7562 AS9492 AS9493 AS9527 AS9577 AS9632 AS9646 AS9709 AS9781 AS9842 AS9947 AS9952 AS9959 AS9973 AS9976 AS10036 AS10049 AS10171 AS10193 AS17592 AS17608 AS17833 AS17837 AS18294 AS18300 AS18305 AS18309 AS18317 AS23588 AS23593 AS24509 AS38098 AS38425 AS38676 AS38686 AS45361 AS45374 AS45968 AS45971 AS45977 AS46011 AS55591 AS131794 AS131820 AS131826 AS131828 AS131866 AS139341 AS152220 AS152294

AS9848 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.
