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.

Totaling in 29586 DFP prefixes and 3317 returned/reclaimed ones.
IPv6 DFP's per country
Total number of countries: 188
V: Visible: Number of Visible Prefixes for this country.
A: Allocated: Number of Allocated Prefixes for this country (excludes returned prefixes).
VP: Visible Percentage: Percentage of visible prefixes against global number of allocated prefixes.
