Summary

Brewer Science

United States · AI-generated

enterprise legacy

The corporate network of Brewer Science, Inc., a specialty-materials company in

Rolla, Missouri that makes thin films and coatings for semiconductor and

microelectronics manufacturing, registered under the handle BREWER-SCIENCE.

What it's used for

  • Enterprise connectivity for the company's headquarters, laboratories, and manufacturing operations, along with its public-facing services.

Notable

  • A single 256-address block. This is a private manufacturer routing its own space, not a provider selling connectivity.
  • ARIN records date the current registration to 2009, so the low AS number is a later reassignment rather than an early-internet allocation.

Interesting

  • Brewer Science is best known for anti-reflective coatings used in photolithography, materials that sit several layers deep inside the chip fabrication process rather than in any finished product.
