About this network

DSIDATA is the AS handle for DSI DATA, a. s., a Slovakian internet service provider operating under the brand name flexi.

What it's used for

• The address space carries residential customer traffic, evidenced by reverse DNS entries like 1009.000.cus.dsidata.sk and 1105.000.cus.dsidata.sk which indicate customer-facing infrastructure.
• With 24,576 IPv4 addresses announced across 7 prefixes and 38 observed neighbours, the ratio suggests a regional access network providing connectivity to end-users rather than a transit provider.
