DASAN Networks, Inc. — 2 prefixes (MA-L)

A MAC address starting with 54:AE:D0 or 18:2C:A9 belongs to DASAN Networks, Inc., a South Korean network-equipment maker, and typically identifies GPON/FTTH broadband CPE, Ethernet switches, xDSL gear, or wireless-access equipment rather than a general-purpose consumer device.

DASAN Networks traces to DASAN Engineering Co., Ltd., founded March 1993 in South Korea, which listed on KOSDAQ in 2000 and renamed itself DASAN Networks, Inc. in 2002. It is headquartered at DASAN Tower in Seongnam-si, Gyeonggi-do, and its product line spans FTTH/GPON, Ethernet switching, xDSL, wireless access, and security-switch equipment.

DASAN Networks is one of several similarly-named but registry-distinct DASAN entities: DASAN CO., LTD. (MA-L 18D071, 00D0CB), DASAN Network Solutions (MA-L 2443E2, 64681A), and DASAN Newtork Solutions [sic, a typo in the registrant name] (MA-L DC4965, F42756) each hold separate IEEE registrant-name rows and are not covered by this entry.

Security researchers disclosed CVE-2018-10561 (authentication bypass) and CVE-2018-10562 (command injection enabling remote code execution) in 2018, affecting DASAN-branded GPON home routers; over one million internet-exposed devices were found via Shodan, and the flaws were reported as actively exploited by the Hajime, Mettle, Mirai, Muhstik, and Satori botnets. No source located ties these CVEs specifically to OUI 54:AE:D0 or 18:2C:A9 as opposed to sibling DASAN/DZS product lines, so this is device-class corroboration only.

Analyst note

A MAC beginning 54:AE:D0 or 18:2C:A9 identifies genuine DASAN Networks, Inc.-registered hardware, most likely GPON/broadband CPE or switching gear; do not conflate with the similarly-named but registry-distinct DASAN Network Solutions, DASAN Newtork Solutions, or DASAN CO., LTD. blocks, which are separate OUI assignments under different registrant-name rows.
