Summary

Delovaya Set - Irkutsk (DSI, ER-Telecom)

Russia · AI-generated

business isp legacy

DSI-IAS — the network of Delovaya Set – Irkutsk ("Business Network Irkutsk",

dsi.ru), a Siberian operator that is now part of JSC ER-Telecom Holding, the

group behind the Dom.ru brand. The RIPE holder field shows the parent; the

network on the wire is still DSI's.

What it's used for

  • Connectivity for organisations across Irkutsk Oblast. Customer addresses resolve as IP-ADDR-irk.cust.dsi.ru and IP-ADDR-ang.cust.dsi.ru — static, per-customer names tagged by city (Irkutsk, Angarsk), with backbone routers as r-CITY-sc.dsi.ru.

Notable

  • Despite the parent being a large consumer ISP, this AS looks like a business access network, not an eyeball one: roughly 21k addresses, no pool-, dyn- or pppoe- subscriber naming anywhere in the rDNS, and DSI is marketed inside the group as a Dom.ru Business asset. ER-Telecom's residential subscribers ride other ASNs.
  • A good example of why a subsidiary should not inherit its parent's kind.
