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 AS17408

25 peers

AS1828 AS7713 AS8966 AS703 AS4775 AS4777 AS5580 AS9002 AS9902 AS10099 AS12389 AS14537 AS38001 AS38855 AS45474 AS59105 AS132337 AS137409 AS138915 AS150766 AS216458 AS18042 AS24482 AS49544 AS63927

AS17408 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 AS17408

6 upstreams

AS3462 AS6939 AS9505 AS10133 AS15412 AS58453

AS17408 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS17408 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS17408

70 downstreams

AS4845 AS7540 AS9269 AS9831 AS9917 AS9920 AS9922 AS10135 AS11179 AS13150 AS17416 AS17651 AS18018 AS18046 AS18186 AS18411 AS18419 AS18422 AS21734 AS24168 AS25152 AS38047 AS38325 AS38797 AS38851 AS38853 AS45593 AS53813 AS55256 AS57976 AS63199 AS63909 AS64078 AS131584 AS131596 AS131599 AS131600 AS131605 AS131606 AS131607 AS131619 AS131620 AS131627 AS131638 AS131645 AS131657 AS131663 AS131680 AS132157 AS133182 AS133847 AS133953 AS134700 AS136041 AS136744 AS139327 AS139750 AS141158 AS150137 AS150767 AS150768 AS150770 AS150771 AS152623 AS198148 AS204844 AS204921 AS208770 AS216198 AS396856

AS17408 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.
