About this network

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.
