Upon hearing your announcement, I went and dig myself a new root.hints
file from one of the root servers. the "D" root is still pointing to the
old address. So I had to go in and manually edit the root.hints file
myself. I blame you for all that extra work :-)

Would there be any impact to having the root servers immediatly provide
the new IP for the D server so that a
dig ns . > root.hints  would yield the new updated
file ?

I realise that keeping the old IP functional for some time is important
for all the static configurations. But does it matter if a dynamic list
is updated "real time" without much advance warning ?
