About this network

NET-CITY-SA is the municipal network of the City of San Antonio, Texas.

What it's used for

• City government networking: departments, offices, public safety, libraries, and municipal services.
• Public-facing city services and the connectivity behind them.

Notable

• Municipal address space is institutional — it serves a city administration, not residents' home internet. San Antonians' broadband comes from commercial ISPs, not from this ASN.
• The footprint is large for a city, a legacy of an era when organizations were allocated public addresses generously and used them directly on internal networks.

Interesting

• Local governments holding low AS numbers are uncommon; most cities came online well after the commercial internet took off, so San Antonio's early presence stands out among municipalities.
