About this network

ERX-AU-NET belongs to Assumption University, a private university in Bangkok, Thailand — widely known by its older name, ABAC. The AS number was originally registered through ARIN and later moved to APNIC as part of the Early Registration Transfer project, which is why the record still carries the ERX- prefix.

What it's used for

• Campus connectivity for the university's Bangkok-area campuses — student and staff networks, labs, and university-run online services.

Notable

• An institutional network rather than a commercial one: the addresses here belong to a single university, not to paying subscribers.
• The holding is unusually large for a single university, on the order of tens of thousands of IPv4 addresses, reflecting an era when address space was handed out generously.

Interesting

• The ERX- naming is a fossil of internet governance history. Registrations predating APNIC's authority over the region originally sat with ARIN and were bulk-transferred to the regional registry, leaving the marker in the object name.
