Iskratel d.o.o. — 5 prefixes (MA-L)

A MAC address starting with 64:6E:EA, 00:D0:50, 54:C2:50, 48:55:41, or 10:A3:B8 belongs to Iskratel d.o.o., a Slovenian telecom equipment manufacturer, typically seen on GPON/XGS-PON optical network gear or Innbox-branded residential VoIP/Wi-Fi routers.

Iskratel is based in Kranj, Slovenia, and operates as a company of the Kontron group. It supplies telecom, rail/transport, public-safety, and energy operators — its own site names customers including Telekom Slovenije and Turkcell.

Five distinct MA-L blocks in the local IEEE registry snapshot share the same organization name and Ljubljanska cesta 24a address, which is itself a signal of an active, recurring hardware manufacturer rather than a one-off registrant. Product lines span GPON/XGS-PON/Combo-PON optical line terminals, Innbox CPE routers and mesh Wi-Fi (e.g. Innbox V60U, V51 R2), and 5G private mobile network equipment.

The one recurring security-relevant fact is that Innbox CPE routers carry documented factory-default credentials, catalogued across multiple third-party router-password aggregator sites. No confirmed CVE or vendor security advisory naming Iskratel or Innbox was found; this reads as a generic weak-default-credential pattern common to consumer/SMB CPE, not a specific exploited vulnerability.

No assignment or registration date is recorded for any of the five blocks. IEEE's public MA-L data does not publish per-block dates, so none is claimed here.

Analyst note

multiple OUI assignments under one identifiable, findable company with concrete device/product context clears the bare-registration bar for this vendor; default-credential reports are a generic CPE weak-config pattern, not a specific exploited vulnerability [Confirmed]
