About this network

ACCESSUS-DOM is accessU.S./BASENet, a small regional internet provider registered in Mt. Vernon, Illinois. It is a mid-1990s ARIN allocation that has stayed with the same holder.

What it's used for

• Five legacy IPv4 blocks (a mix of /18s and /19s) totalling roughly 65,000 addresses, reaching the internet through a single upstream: Charter Communications' Missouri/Illinois network.

Notable

• The address space is far larger than the network's present-day footprint suggests — very little of it carries reverse DNS or hosted content, which is typical of a 1990s dial-up-era ISP allocation that was never given back.
• A single-upstream, single-region network rather than a transit or hosting operator.
