About this network

The network of Alameda County, California, which covers Oakland, Berkeley, Fremont and the rest of the East Bay.

What it's used for

• County government networking: administration, courts, health services, public safety and the rest of a large local authority's estate.

Notable

• One prefix, announced whole: 166.107.64.0/18, registered as ALAMEDA with the county's network services group as the contact. 16,384 addresses, no deaggregation, three observed BGP neighbours.
• No IPv6 announced.

Interesting

• The AS handle is ALAMEDACOUNTYDATAPROCESSING. Data Processing was the standard name for a government IT department in the era this was registered, before the function was renamed to Information Services and then to Technology. The department has almost certainly been renamed since; the AS handle has not.
