        Who says SRI-NIC knows who the root servers are. Below is the
contents of a NS lookup of the root servers directed to SRI-NIC. Note
that it lists itself, C.ISI.EDU (which is shutoff today), BRL-AOS.ARPA
and A.ISI.EDU. However for additional records it only supplies an A
record for SRI-NIC and BRL-AOS. C.ISI.EDU and A.ISI.EDU are not
provided with A records.
