Re: ROVER routing security - its not enumeration

...

There are number of operational models that provide the needed routing protection without enumeration. I can see a use-case for something like: "Build me a prefix list from the RIR data"

this requires a full data fetch, not doable in dns. and, at the other end of the spectrum, for any dynamic lookup on receiving a bgp announcement, the data had best be already in the router. a full data set on an in-rack cache will go nuts on any significant bgp load. beyond that, you are in non-op space. randy
