Elitegroup (ECS) registrations identify computer hardware interfaces. A prefix match cannot identify a particular motherboard or finished system.

Apple registers address blocks used across its computers and mobile devices. A matching prefix identifies the registered interface vendor, but cannot identify an iPhone or Mac model.

Hon Hai (Foxconn) is a contract manufacturer. Its registry name may appear on devices sold under another brand because the address belongs to the manufactured interface.

TP-Link prefixes appear on routers and other network interfaces. One router can have several addresses for LAN, WAN and wireless interfaces; the lookup does not identify which role an address serves.

Cisco prefixes occur on routing, switching and wireless equipment. A switch may expose different addresses for its physical interfaces and logical interfaces; a prefix match alone does not reveal its model.

Huawei registers prefixes for networking and consumer hardware. Use a lookup alongside your switch or wireless inventory; the prefix alone cannot distinguish a phone from network infrastructure.

Realtek supplies network interface chips to many hardware manufacturers. A Realtek match can identify a component supplier even when the device carries a different brand.

This registration names a manufacturing or component supplier. The finished product can carry another brand, so compare the lookup with device inventory rather than treating it as a model identifier.

Dell prefixes are used on computers and servers. A Dell system may also contain a network interface registered to Intel or another component supplier.

Tenda registers address blocks for network interfaces. A router may have separate addresses for its wired and wireless roles; the prefix alone cannot identify the role.
