Megafone Limited — 3 prefixes (MA-L)
Summary
- // what this is
- Megafone is registered to MAC prefix
20:36:5Band 2 more in the IEEE OUI database. When a device's MAC address begins with20:36:5B, that block was registered by Megafone — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- OUI hits on these three prefixes identify a genuine, multi-block registrant (Megafone Limited, HK) but do not indicate device type; don't assume a specific product category from the vendor name alone.
About this vendor.
A MAC address beginning 20:36:5B, 80:DA:BC, or F0:0E:1D belongs to Megafone Limited, a Hong Kong-registered company holding three separate IEEE MA-L OUI assignments — but no evidence found in this research identifies what specific device category these addresses actually appear on.
IEEE's public OUI registry lists all three prefixes under the identical organization name and Hong Kong registry address, and an independent third-party lookup (maclookup.app) corroborates that all three map to the same registrant. That cross-source agreement confirms a genuine multi-OUI vendor, not a single opportunistic registration.
Hong Kong corporate registry records show a company named Megafone Limited: a private company limited by shares, incorporated 2013-12-10 (BRN 62472043), status Live. This is a first-party HK corporate-registry fact, separate from any IEEE OUI assignment date, which IEEE does not publish for any registrant.
No product listings, device teardown reports, or fingerprint-database entries were found identifying what hardware Megafone Limited manufactures, and no CVEs, malware analyses, or security advisories reference the company or its three prefixes specifically. Any device-type inference for these OUIs should be treated as unverified.

- Related vendors
- none identified
- Analyst note
- three independently-corroborated OUI assignments plus a real, findable Hong Kong corporate registration establish this as a genuine multi-OUI vendor, not a bare shell registration — but with zero product/device evidence, OUI hits on these prefixes confirm "Megafone Limited" as the manufacturer of record without confirming a device class.
