ASNs, Domains, IP ranges Description
The constituency of the Proximus CSIRT is twofold:
- ISP-customers and commercial-customers: services that Belgacom offers.
- Commercial-organization: employees of the Belgacom Group

The Proximus CSIRT is not intervening for cyber security incidents, that are not occurring on Proximus managed infrastructure. That means that consumer equipment (eg laptop) does not fall in the scope of the Proximus CSIRTs responsibilities. Affiliates (Telindus NL, Telindus UK, Telindus LU, Tango LU, BICS) are part of the commercial-organization constituency.
In general, the full AS5432 is owned by Proximus. However, these also include IP addresses that are statically or dynamically assigned to customers for which Proximus will not be intervene outside of the legal framework that we are bound to operate in.
