Nsolution Co., Ltd. is a South Korean network-security appliance maker holding the MA-L block 98:10:82, registered to a Gyeonggi-do address at 1001-1, 387 Simin-daero, Dongan-gu, Anyang-si. The MA-L assignment (a 24-bit OUI) covers the full 98:10:82:00:00:00–98:10:82:FF:FF:FF range, roughly 16.77 million addresses. The company's flagship product is NetSpliter, a dedicated VPN gateway-plus-client appliance that physically separates a hardened security channel from general network ports, so an internal security zone is reachable only through approved client devices; product literature lists modest embedded hardware (750 MHz dual-core CPU, 512 MB RAM, 256 MB flash). NetSpliter V2.0 carries a Korean Common Criteria certification (KECS report CR-17-68) from the IT Security Certification Center. The vendor name is a notable disambiguation trap: at least two unrelated firms share the "nsolution" name — an Albanian ISP (nsolution.al, Tirana) and a U.S. infrastructure-automation vendor (nSolutions Inc.) — but only the South Korean Nsolution Co., Ltd. holds this OUI prefix. No CVEs or public vulnerability disclosures were found for the company or NetSpliter in this research pass. As with all OUIs, IEEE publishes no registration date; a "17 April 2021" date seen on a third-party lookup is a database artifact, not an IEEE fact.

- Disambiguation
- distinct from NSolution (nsolution.al), an Albanian ISP/IT-services firm in Tirana, and from nSolutions Inc., a U.S. infrastructure-automation vendor (NOVA appliance); only the South Korean Nsolution Co., Ltd. holds 98:10:82 [Confirmed] — https://www.nsolution.al , https://www.linkedin.com/company/nsolutions-inc.
- Analyst note
- 98:10:82 reliably identifies genuine Nsolution hardware (a low-volume Korean security-appliance vendor); the registered address sits in the Anyang-si Simin-daero tech corridor alongside other Korean network-hardware firms (e.g. WooriNet).
