Agranat Systems, Inc. — 00:90:B3 (MA-L)

Agranat Systems is the registered name on IEEE MA-L block 00:90:B3, assigned to an address at 1345 Main Street, Waltham, MA. The name belongs to a real, identifiable embedded-systems software company founded and led by Ian Agranat, best known for "EmWeb," a small-footprint (roughly 25KB) embedded HTTP server toolkit that let OEMs add web-based management interfaces to microprocessor-based devices such as datacom/telecom gear, office peripherals, test-and-measurement equipment, and industrial controllers. Trade press from the late 1990s documents named enterprise licensees — 3Com, ABB, Cabletron, Canon, Hewlett-Packard, Lucent, Nortel Networks, Siemens, Teradyne, and Xerox — giving the company a credible footprint well beyond a bare OUI registration. Agranat also held embedded-web-server patents (US 6,456,308 among them) and related international filings. In August 2000 the company was acquired by Virata Corporation and continued operating as a Virata subsidiary out of Maynard, MA, ahead of Virata's later merger path into Conexant/GlobespanVirata. No MA-M or MA-S block exists for the name, so this single MA-L prefix appears to be the company's only IEEE assignment; given Agranat's software-licensing business model, the registered hardware is most plausibly reference or evaluation gear used to demonstrate EmWeb rather than a high-volume shipped product line — an inference from the documented business model, not a directly sourced fact.

IEEE assignment

00:90:B3 → AGRANAT SYSTEMS, registered Waltham, MA, US [Confirmed] — the IEEE MA-L registry

Registry / block size

MA-L (24-bit OUI); one block in the cached registry [Confirmed] — the IEEE MA-L registry

Registered address

1345 Main Street, Waltham, MA, US, 02154 [Confirmed] — the IEEE MA-L registry

MA-M / MA-S holdings

none found — no Agranat Systems entry in the IEEE MA-M registry (MA-M) or the IEEE MA-S registry (MA-S); holds only the single MA-L block [Confirmed] — the IEEE MA-M registry, the IEEE MA-S registry

Cross-reference

Wireshark the Wireshark manufacturer database DB line 16001 lists 00:90:B3 as "Agranat" / "Agranat Systems," consistent with the registry (non-authoritative confirmation only) [Confirmed] — the Wireshark manufacturer database

Product

EmWeb — ~25KB-footprint embedded HTTP 1.1/XML/HTML server for OEM web-management interfaces on microprocessor-based devices [Confirmed] — embeddedtechnology.com; internetnews.com

IP / patents

US 6,456,308 (embedded web server) plus related filings WO1998006033A1 and EP0853788A1 [Confirmed] — freepatentsonline.com; patents.google.com

Acquisition history

acquired by Virata Corporation, August 2000; continued as a Virata subsidiary in Maynard, MA ahead of Virata's later merger into Conexant/GlobespanVirata [Confirmed] — en.wikipedia.org (Virata Corporation); embeddedtechnology.com

Likely device context

business model was software/IP licensing to OEMs (who embedded EmWeb in their own routers, switches, and controllers); no source ties the 00:90:B3 prefix to a specific named shipped product — most plausibly Agranat's own reference/evaluation hardware

[Likely] — inferred from documented business model

Registration date

none — IEEE publishes no OUI assignment date and the cached registry CSV has no date column; any "date registered" on third-party MAC-lookup sites is a database artifact, not an IEEE fact [Confirmed] — the IEEE MA-L registry

Security context

no CVEs, advisories, or vendor-specific incident history found for Agranat Systems or EmWeb in this pass; treated as no-finding, not confirmed-clean [Unknown]

Analyst note

Single-OUI vendor with a well-documented independent paper trail (named founder, product, patents, customers, trade-press coverage, and a traceable 2000 acquisition), clearing the company-substance bar despite holding only one IEEE block; the company's own web presence is defunct (Virata subsidiary, then folded into later mergers), so live 00:90:B3 devices in the field are plausible but undocumented.
