I've had a few questions about the data I posted. That was a total of
all ribs I have access to, not a summary of uniques. I thought maybe a
report of OIX would be a better example. Here's the full rib report:
Total prefixes seen in RIB: 238997
Total origin ASes seen in RIB: 26514
Total 32 bit ASes seen in RIB: 0
Total peer pairs seen in RIB: 55947
RIB Peers not found in all other tables: 4
RIB Prefixes not exactly matched in all other tables: 123
RIB more specific prefix count: 123
Number of unique prefixes in RIB compared against all data: 123
Number of unique origin ASes in RIB compared against all data: 4
Number of ASes announcing only one prefix: 11229
Number of Transit Only ASes: 125
