About this network

CCS-AS belongs to Clare Computer Solutions, an IT managed-service provider based in San Ramon, California, serving businesses in the San Francisco Bay Area.

What it's used for

• The company's own network and the IT services it delivers to client businesses — managed IT, network support, and related infrastructure work.
• A single /24 (256 addresses), which is a small business footprint.

Notable

• ARIN's registration for AS5081 dates to June 1995, placing it among the genuinely early entries in this part of the number space.
• A regional MSP holding its own AS number is unusual today; most operate entirely inside their upstreams' address space.
