About this vendor.
A MAC address beginning 00:1E:57 matches an IEEE MA-L assignment registered to ALCOMA, spol. s r.o.; the prefix alone does not identify a particular device. The supplied company history describes ALCOMA as a Czech developer and manufacturer of microwave point-to-point radio links. It says the company began making radio links in 1994 and that ALCOMA spol. s r.o. transformed into a joint-stock company on 1 July 2012.
The company page describes Ethernet, PDH, and SDH links, antennas, and IDU-ODU and all-outdoor configurations. That catalog information is company context only: the evidence does not map these products or any device category to 00:1E:57.
This is one 24-bit prefix. Its first octet is 00, so the Group and Local bits are both zero. Matching fixes the first 24 bits; the remaining 24 bits allow 16,777,216 suffix values, not a count of devices or shipments. A captured match supports the registry-assignment association, not the identity, location, or security state of a device.
