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 AS9931

4 peers

AS10099 AS24187 AS24482 AS38794

AS9931 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 AS9931

2 upstreams

AS4651 AS38040

AS9931 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS9931 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS9931

47 downstreams

AS72 AS7715 AS7862 AS8674 AS9335 AS9464 AS9649 AS17468 AS18197 AS18252 AS18409 AS23900 AS24042 AS24060 AS24190 AS24328 AS24393 AS38228 AS38265 AS38293 AS38296 AS38328 AS45533 AS45575 AS45806 AS46071 AS63972 AS131089 AS132133 AS133947 AS134565 AS134695 AS134811 AS135566 AS135635 AS136035 AS137058 AS137850 AS140618 AS140699 AS141214 AS141692 AS147300 AS150716 AS152130 AS152463 AS153746

AS9931 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.
