Summary
Cirrus Logic, Inc.
enterprise legacy
Corporate network of Cirrus Logic, Inc. (CIRRUS), the fabless semiconductor
company headquartered in Austin, Texas.
What it's used for
- Corporate and engineering networking for Cirrus Logic's own sites.
- A small footprint (about 1,000 IPv4 addresses) consistent with an enterprise serving its own staff and infrastructure rather than customers.
Notable
- This is a corporate network, not an eyeball ISP: addresses here belong to a chip designer's offices and internal systems, so traffic from this range is business rather than residential.
- Cirrus Logic is best known for audio and mixed-signal converter chips used in consumer electronics.
Interesting
- The low AS number and the ARIN registration date of 1994 place Cirrus Logic among the companies that took their own ASN very early, back when a single corporation with an internet connection was still unusual.
