DiG has supported ixfr over udp since 2007. It just defaults to TCP. you have to disable TCP after specifying ixfr. e.g. dig ixfr=2007111878 dv.isc.org +notcp > You could try setting "request-ixfr no;" to see if AXFR (over TCP) works > better. > > Tony. > -- > f.anthony.n.finch <d...@dotat.at> http://dotat.at/ > Shannon: Northwest 5 to 7, decreasing 4 or 5.
