About this network

SMART-CITY-HQ belongs to Smart City Networks, the Las Vegas-headquartered company that provides the internet, Wi-Fi and voice infrastructure inside American convention centres. It is the in-house telecom provider at dozens of large exhibit halls, selling connectivity to venues, show organisers and individual exhibitors.

What it's used for

Venue connectivity. RIS observes 26 IPv4 prefixes and roughly 14,592 addresses, no IPv6, and just one BGP neighbour — a single upstream carrying a geographically scattered but functionally uniform network.

The reverse DNS maps the business almost building by building. Every sampled name sits under smartcity.com with a venue code in front of it: scnhq-66-78-200-5 (the Las Vegas headquarters), lacc-66-78-232-5 and lacc-24-56-184-5 (Los Angeles Convention Center), lbcc-96-8-36-5 (Long Beach), fwcc-24-75-240-5 (Fort Worth), plus kecc, cncc and cbcc blocks. Each convention centre gets its own address range out of the same pool.

Notable

Every announced prefix is registered to a Smart City SCN- ARIN block, so despite address space drawn from half a dozen unrelated-looking /8s (24., 66., 67., 96., 208.), this is entirely first-party space. The scatter is an artefact of acquiring blocks over decades, not of leasing.

Interesting

Traffic on this AS is spiky in a way almost no other network is: an exhibit hall is dark for weeks, then carries tens of thousands of simultaneous users for four days. The addressing reflects it — large per-venue pools that are mostly idle.
