About this network

CYBERCON — Cybercon, Inc., a data-centre and hosting company founded in 1995 and operating out of 210 N. Tucker Blvd. in downtown St. Louis, Missouri, one of the city's main carrier hotels.

What it's used for

• Colocation, dedicated servers, and private-cloud hosting. Reverse DNS on the announced space is unmistakably hosting: names like cp12.ezhostingserver.com and platinum.classcreator.com — control panels and customer web properties.
• The ASN announces roughly 55k IPv4 addresses across ~140 prefixes.

Notable

• Hosting address space, not eyeball: no DSL, cable, or CGNAT-style subscriber hostnames appear anywhere in the block.
• The prefix list is worth noting for its shape — a US-registered ASN announcing a long tail of mostly-/24 prefixes drawn from European (RIPE) address ranges alongside its ARIN space. That pattern usually means leased or acquired address blocks rather than organically grown allocations.

Interesting

• Cybercon is one of the older independent hosting companies still operating under its original name, with an ASN registered in 1996 — barely a year after the company was founded.
