AS9251 — INTERLINK-TECH-AS-ID PT INTERLINK TECHNOLOGY

Network type: residential

AS9251 announces 1 IPv4 prefixes covering 256 addresses and 0 IPv6 prefixes.

About this network

AS9251 (INTERLINK-TECH-AS-ID) is held by PT Interlink Technology, a Jakarta-based internet service provider. Interlink sells bandwidth and connectivity, server colocation and managed network services, operating over fibre, radio link and satellite, and is based in the Cyber Building — Jakarta's main carrier-dense interconnection address.

What it's used for

The reverse DNS confirms the holder without ambiguity: sampled addresses resolve to ip-103-253-106-5.interlink.net.id and ip-103-253-106-133.interlink.net.id, the operator's own templated naming on its own domain.

The routing is small but the shape is telling. RIS sees a single prefix, 103.253.106.0/24 — 256 addresses — with no IPv6, yet 8 observed neighbours. That combination is the interesting part of this card. A /24 with eight BGP adjacencies is not an enterprise stub; it is a network that is well interconnected relative to the address space it announces, which is what a provider looks like when it peers actively at local exchange points from a carrier-dense facility. Interlink runs the bulk of its business through a different, larger autonomous system, so AS9251 is best read as a secondary AS: a small block held and announced separately, with the peering fabric of the wider operation behind it.

Notable

• Interlink's primary network is a different ASN; this one carries only a single /24, so it is not a good proxy for the operator's overall footprint.
• The company is located in Gedung Cyber in Jakarta, the interconnection hub that explains the high neighbour-to-address ratio.
