How it works ("old-style")
THE GRH PROJECT HAS BEEN CONCLUDED
As IPv6 Routing Stability has improved over the years we have concluded the GRH project.
The GRH pages remain for a historical perspective.
The ULA Registry remains active.
GRH (Ghost Route Hunter) is a centralized mechanism for collecting routes and detecting the anomalies therein. We keep a history of these Ghost Routes providing a means of visualizing the problem. The ultimate target is to have no ghosts at all. As we have availability over several BGP tables we also collect prefix statistics and provide a distributed looking glass into these tables.
The Ghost Route Hunting process has the following four steps:
A snapshot of all the collected tables are kept per day in the archives. All the ghosts are kept per 10 minutes.
