About this network

RGNET-DFW is one of the autonomous systems of RGnet, the small network run by internet routing researcher Randy Bush. The name marks its home: an Equinix facility in Dallas.

What it's used for

• A tiny, deliberately minimal network. It announces a single IPv4 /24 and is operated as one of RGnet's site presences rather than as a commercial service.
• RGnet's networks are long associated with internet routing and measurement work, so this address space behaves more like a research and operations vantage point than like a customer network.

Notable

• The resource is held as a RIPE legacy object under RGnet OÜ, an unusual arrangement for a network whose routing presence is in the United States.
• RGnet operates more than one low ASN, and they are recognisable in routing data by how little they announce compared with their prominence in the operator and standards community.

Interesting

• Networks like this are why the internet's measurement infrastructure works at all: a handful of small, well-run ASNs held by researchers provide the vantage points that routing studies depend on.
