don't want to file a decom report with a gap so I figured I would ask here.

On a contract job clearing out a data center doing routine stuff like taking inventory and audits before we decommission hardware. The issue is there is one node that keeps coming back that isn't in the documentation. ip is in the 46.28.x.x range Its not in the facilities registry though. Ran it through RIPE and ARIN to find nothing.

The latency is what is getting me though. 0.4 round trip every time. Tested from multiple machines including a phone on LTE to get the same response time. That should theoretically mean I am right next to the machine which doesn't make sense across three different connections.

Checked the physical hardware and it's nothing I've ever seen before. Not standard 1U or 2U ports maybe proprietary. serial format is:

CC-[4 digits]-[2 digits]-[6 alphanumeric]

CC prefix doesn't math Cisco, Ibm, Dec, 3com or anything. went back through the facility's historical logs. node appears in their earliest available records, which go back to 1994. facility was built in 1997.

has anyone seen a CC- serial prefix before? or have an explanation for the latency consistency?
