It should be the root zone master file.
However authoritative server implementations differ in whether they echo
the query case or preserve the master case. e.g. a.root-servers.net
(running Verisign ATLAS) echoes case, f.root-servers.net (running BIND)
preserves case. k.root-servers.net is amusing because it runs a load
balancer in front of BIND, Knot, and NSD; Knot and NSD echo case, so
K-root's case handling behaviour is unpredictable.
