NAGTECH LLC — 3 prefixes (MA-L ×2, MA-S ×1)

A MAC address starting with F8:F0:82 or 8C:AE:DB belongs to NAGTECH LLC, a networking-equipment manufacturer based in Yekaterinburg, Russia, and typically identifies an SNR-series L2+ managed Ethernet switch such as the SNR-S5210 (24x1GbE + 4xSFP+, PoE variants available) or the SNR-S5311 (48x1GbE + 6xSFP+, 216Gb/s switching capacity).

NAGTECH holds three separate IEEE registrations rather than a single bare OUI: two MA-L (24-bit) blocks — F8:F0:82 and 8C:AE:DB — plus one MA-S (/36) sub-block reported as 8C:1F:64:29:F, all registered to the same Ekaterinburg address. Multiple independent assignments to one registrant, paired with a live vendor site and downloadable datasheets and firmware, distinguish this from a shell registration with no verifiable substance beyond a bare IEEE listing.

The MA-S sub-block sits under 8C:1F:64, a base the IEEE Registration Authority sub-allocates in small /36 slices to thousands of unrelated companies. NAGTECH owns only its one narrow slice beneath that base — not the base itself — so a MAC merely starting 8C:1F:64 cannot be inferred as NAGTECH hardware; only the specific slice identifies it, and even that slice's final hex nibble is reported inconsistently across third-party sources.

NAGTECH's product line reportedly extends beyond switches to IoT controllers, IPTV set-top boxes, and wireless routers, per the vendor's own site, though the confirmed device/OUI pairing supported by product documentation is the SNR switch line. No CVE is recorded in the NVD for NAGTECH, NAGTECH LLC, or the SNR-S5210/S5311 lines as of an August 2026 search.

IEEE assignment

F8:F0:82 (MA-L), 8C:AE:DB (MA-L) → NAGTECH LLC, registered Ekaterinburg, Sverdlovskaya oblast, RU [Confirmed] — the IEEE MA-L registry F8F082, the IEEE MA-L registry 8CAEDB

MA-S sub-block

8C:1F:64:29:F → NAGTECH LLC (final hex nibble reported as either 4 or F across third-party sources; the project's own registry row is authoritative) [Likely] — the IEEE MA-S registry 8C1F6429F

Registry / block size

MA-L (24-bit, 2 blocks) + MA-S (/36 sub-block, 1 block) [Confirmed] — the IEEE MA-L registry, the IEEE MA-S registry

HQ / address

12A, Krasnolesya Str., off 507, Ekaterinburg, Sverdlovskaya oblast, RU 620110 [Confirmed] — the IEEE MA-L registry F8F082

Company status

active — live vendor site with current product documentation [Confirmed] — https://nagtech.systems/

Device types

L2+ managed Ethernet switches (primary, confirmed); IoT controllers, IPTV set-top boxes, wireless routers (secondary, per vendor site) [Confirmed primary / Likely secondary] — https://nagtech.systems/

Notable products

SNR-S5210 series (24x1GbE + 4xSFP+, PoE variants), SNR-S5311 series (48x1GbE + 6xSFP+, 216Gb/s switching capacity), vendor OS "eNOS" [Confirmed] — https://data.nagtech.systems/switches/S5210/Datasheet/, https://snr.systems/site/data-files/snr.global/Products/SNR%20Switches/5210%20Series/Guides/SNR-S5210_configuration_guide.pdf

Shared-base caveat

8C:1F:64 is an IEEE-RA base sub-allocated in /36 slices to thousands of unrelated registrants; NAGTECH holds only its one slice, not the base [Confirmed] — the IEEE MA-S registry

Security context

no CVE recorded in the NVD for NAGTECH or its SNR-S5210/S5311 lines as of an August 2026 search [Likely] — https://nvd.nist.gov/vuln

Third-party registration dates

maclookup.app/macaddress.io display "date registered"/"last updated" values for these prefixes; these are third-party database artifacts, not IEEE-published facts — IEEE's own OUI/MA-S registry publishes no assignment date [Confirmed] — https://maclookup.app/macaddress/f8f082
