< / code > < / pre > < p > I had been regenerated the < code > sitebndl.zip< / code > file on the CGIAR Library server and sent it to the Handle.net admins but they said that there were mismatches between the public and private keys, which I suspect is due to < code > make-handle-config< / code > not being very flexible. After discussing our scenario with the Handle.net admins they said we actually don’ t need to send an updated < code > sitebndl.zip< / code > for this type of change, and the above < code > config.dct< / code > edits are all that is required. I guess they just did something on their end by setting the authoritative IP address for the 10947 prefix to be the same as ours… < / p >
