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 AS17621

0 peers

AS17621 has no peers recorded.

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 AS17621

2 upstreams

AS4837 AS9929

AS17621 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS17621 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS17621

37 downstreams

AS109 AS7609 AS9809 AS10100 AS10212 AS17739 AS17775 AS23853 AS24141 AS37963 AS37965 AS38375 AS38381 AS45073 AS45079 AS45110 AS55956 AS55992 AS55996 AS56006 AS56013 AS58593 AS58850 AS59019 AS59083 AS63538 AS63570 AS63603 AS63641 AS135432 AS137715 AS137746 AS137759 AS137782 AS139148 AS146842 AS151247

AS17621 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.
