Ghost Route Hunter : IPv6 DFP visibility

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.

These pages show the visibility of Default Free Prefixes (DFP's) as delegated by the RIR's.
This is seen from the ISPs as listed on the Ghosts pages.
If a prefix is seen by any of these ISPs it is counted as 'visible', the number of ASPaths gives as slight inside how many working peerings where visible at that timestamp.

DFP visibility per RIR

All RIR's in one overview.

Missing DFP's per GRH participant

The following form allows you to check which GRH participants are missing which prefixes.

Prefix Length distribution

The following prefixlengths are delegated by the above RIR's.
