Split the zone files. You notice I had aa.bb.cc.dd not aabbccdd. - thats
how the in-addr.arpa domain works and it replicates fine.

I dont claim DNS does this. I claim NNTP does not because it doesn't solve
the case where through partial connectivity and the fact its too slow to
search the entire history for all time for missing entries some people dont
get an entry. Nor does NNTP solve the case where two entries collide and
are submitted from different sites.

You want a central but relocatable sanity point. BTW - one thing that
did occur to me - we can use cddb quite legally and above board to sanity
check our submissions. Same key, doesnt look similar to the cddb entry - mark
as suspicious.

The other mirror servers cover it transparently. DNS does that for free

To me thats a long form of "doesnt work". Thats not to say it can't be made
too. NNTP doesnt solve the querying or query caching. Maybe you use an NNTP
like protocol to populate your DNS servers ?
