Despite the very un-well defined definition for "global routing table", I'm going to assuming something similar to the DFZ, or the set of prefixes which is seen in all (most of?) the transit-free networks[*]. Given that definition, there are exactly zero /25s in the GRT (DFZ). And unlikely to be for a while. Whether "a while" is "next 12 months" or "several years" is something I am very specifically choosing not to answer. -- TTFN, patrick [*] Don't you hate the term "tier one" these days? It doesn't mean what it used to mean (i.e. _settlement free_ peering with all other tier one networks). And given that there are non-transit-free networks with more [traffic|revenue|customers|$WHATEVER] than some transit free networks, I prefer to not use the term.
