What is the OUI E8:B8:53?

E8:B8:53 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to GSD VIET NAM TECHNOLOGY COMPANY LIMITED. It covers every address from E8:B8:53:00:00:00 to E8:B8:53:FF:FF:FF, or 16,777,216 addresses in total. It is also written E8-B8-53.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E8:B8:53:00:00:00 that is E8:B8:53 — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.

Where is GSD VIET NAM TECHNOLOGY COMPANY LIMITED located?

GSD VIET NAM TECHNOLOGY COMPANY LIMITED is listed at PART OF FACTORY 2, LOT C2.10, D1 STREET, DONG AN 2 INDUSTRIAL PARK, BINHDUONG WARD HO CHI MINH CITY HO CHI MINH VN 820000 in the IEEE OUI registry entry for E8:B8:53.
