Summary

// what this is
Advanced Switching Communications is registered to MAC prefix 00:90:26 in the IEEE OUI database. When a device's MAC address begins with 00:90:26, that block was registered by Advanced Switching Communications — the OUI identifies the maker of the network hardware, which is not always the brand on the device. Advanced Switching Communications has ceased operations, but the registration remains on record with IEEE.
// analyst note
Single-OUI registrant, but verifiable company substance (SEC IPO filing, named products/customers, address match) clears the abstain-on-shells bar. No security/CVE history surfaced in this pass — treat as unknown, not as a clean bill of health.

About this vendor.

Updated  ·  Confidence: Medium

Advanced Switching Communications, Inc. holds a single IEEE MA-L block, 00:90:26, registered to the company at 8330 Boone Boulevard, 5th Fl., Vienna, VA 22182, US. Unlike many single-OUI registrants that turn out to be shell filings, this one is backed by verifiable corporate substance: the company was founded in September 1997 and filed SEC Form S-1 and S-1/A paperwork (CIK 1095583, FY2000) for a proposed IPO, describing itself as a provider of "next-generation broadband access platforms" for telecom carriers, with named customers including UUNet, Intermedia Communications, and Broadview Networks. Archived third-party datasheet mirrors reference specific shipped products — the A4000 ("Affordable PoPs") and the A1240, a 24-port T1/E1 access platform for ATM, Frame Relay, and TDM traffic — consistent with the S-1's business description. The company did not survive the dot-com bust: an SEC 8-K reports stockholders approved a plan of liquidation around April 12, 2002, with a certificate of dissolution intended around May 10, 2002. No second OUI block was found under this registrant name, and IEEE's public registry publishes no assignment date for 00:90:26, so none is recorded here.
