Several people have forwarded to me a message you sent to NANOG saying that
the problem with the RFC 1918 delegations was fixed yesterday. As far as I
can tell, this is not true. I'm still seeing lame responses from both
blackhole.isi.edu and ns2.internic.net (which replaced rs0.internic.net in
the delegations yesterday).
Also, we have a system here configured as a secondary server for the RFC
1918 domains, so that we can point customer firewalls to it for their zone
transfers (this way, if the original primary moves, we only have to update
one system, not all the firewalls). It used to use ns.isi.edu as its
primary, but that stopped working on 3/25. Is there a machine that can be
used instead?
