About this prefix.
4C:D7:3A is registered to Shenzhenshi Xinzhongxin Technology Co.,Ltd, CN. That page carries the full record: every prefix the organisation holds, its registered address, and the research behind the entry.
4C:D7:3A is an OUI: the first three octets of a MAC address. Every address beginning with these octets was issued from this block. The remaining three octets are assigned by the block holder to individual network interfaces, so one 24-bit block spans 16,777,216 addresses.
The IEEE Registration Authority is the source of record for these assignments. A 24-bit block can belong to one organisation outright, or be divided into smaller MA-M and MA-S ranges held by several unrelated registrants.
