ShenZhen Rapoo Technology Co., Ltd. — 2 prefixes (MA-L)

A MAC address starting with 6C:5D:63 or E4:12:18 belongs to ShenZhen Rapoo Technology Co., Ltd., typically seen on wireless computer mice, keyboards, and the USB nano receivers/dongles paired with them.

Rapoo is a real, identifiable operating company, not a bare registry entry: founded 2002, headquartered in Shenzhen, Guangdong, and publicly traded on the Shenzhen Stock Exchange (ticker 002577). It sells wireless mice, keyboards, combos, gaming headsets, and video-conference gear under its own brand via rapoo.com and regional storefronts.

The vendor holds two separate MA-L (24-bit) OUI blocks, each registered directly and exclusively to "ShenZhen Rapoo Technology Co., Ltd." at two different Shenzhen addresses — BaoAn district for 6C:5D:63, Pingshan district for E4:12:18. Neither is a slice of a shared IEEE Registration Authority base like 70:B3:D5; both are dedicated blocks this company owns outright.

Third-party aggregator maclookup.app displays "2011-03-17" and "2014-03-11" next to these two blocks, but those are that site's own database timestamps, not IEEE facts — IEEE's public the IEEE MA-L registry publishes no assignment-date field for MA-L registrations at all.

On security, Rapoo does not appear on Bastille Networks' MouseJack list of affected wireless-input vendors, and no CVE for a Rapoo RF protocol flaw turned up in an August 2026 search. Heuristic "malicious activity" scores on sandboxed Rapoo driver installers are not corroborated by any antivirus engine (0 of 70 flagged) and match normal input-driver API usage, not confirmed compromise.

Shared-base check

neither 6C:5D:63 nor E4:12:18 is a shared IEEE-RA base (unlike 70:B3:D5 or 8C:1F:64); both are exclusive MA-L assignments [Confirmed] — the IEEE MA-L registry 6C5D63, E41218; https://maclookup.app/vendors/shenzhen-rapoo-technology-co-ltd; https://www.adminsub.net/mac-address-finder/e4

Registration-date caveat

maclookup.app shows "2011-03-17" (6C5D63) and "2014-03-11" (E41218) as its own crawl/database timestamps; IEEE's MA-L registry contains no assignment-date field, so these are not IEEE registration dates [Confirmed] — https://maclookup.app/vendors/shenzhen-rapoo-technology-co-ltd

Security context — MouseJack

Rapoo is not listed among tested/affected vendors (AmazonBasics, Dell, Gigabyte, HP, Lenovo, Logitech, Microsoft) as of an August 2026 check [Confirmed negative] — https://bastille.net/research/vulnerabilities-mousejack/

Security context — CVE

no CVE record found in an August 2026 search for a Rapoo wireless-receiver/keyboard RF vulnerability; not directly queried against NVD's own database [Unknown]

Security context — driver installer sandbox flags

ANY.RUN and Hybrid-Analysis heuristics scored sampled Rapoo driver installers as "malicious activity"/100, but 0 of 70 antivirus engines on Hybrid-Analysis flagged the sample, and the flagged APIs (GetKeyboardState, GetRawInputData) are normal for an input-device driver — treated as heuristic false positive, not confirmed compromise [Likely] — https://any.run/report/06bd27c8f2bea255777184610cf58496ede70ef4b226d6dbb0ab1a7dbd448d59/71fc70e4-615e-48a1-a9c0-2ee7173672ee, https://hybrid-analysis.com/sample/d60a79ed41877be4a47ea0ca9291db7c2e1b28213204b84806ef8c35bd22da23/5d73c416028838d781c9b6a3

Prefix-to-model mapping

no public source maps a specific product model to 6C:5D:63 or E4:12:18 specifically; only aggregator pages attribute the whole prefix to Rapoo generically [Unknown]

Related vendors

none identified [Unknown]

Analyst note

MACs beginning 6C:5D:63 or E4:12:18 reliably identify Rapoo-registered hardware — both blocks are owned outright, not shared IEEE-RA bases — and the wireless-input product line (mouse/keyboard + paired receiver) plausibly consumes this address space, but no source ties either prefix to one specific product model.
