This boils down to checking two list of names to see if they are
the same. We have tools that will give you the lists. I could ask
a 12 year old if two list of names are the same and get the correct
No, this is not rocket science and never has been.
Designing the tools to do the lookup in the first place was but we
have the tools to do that and they have existed in one form or
another since RFC 1034 was written. They existed in 1992 when I
started working on the DNS.
This is nothing more than text processing which lots of non-scientists
have been doing for centuries. There is nothing here which businesses
have not been doing for centuries in one form or another. Does the
list of goods you got match the list of goods you ordered?
No, this is not rocket science. Just because you get the answer
from the DNS does not make it rocket science. If there was any
thought that this was rocket science the proceedures for checking
the names and addresses would have been specified.

These are all checkable. It doesn't take massive resources to make

Which just means ICANN stuffed up.
