IP Adress mismatch should not matter. What is the actual error you saw?
The mismatch might be unintentional.
The reason I say ip address should not matter is that if you change the
ip address of a datanode, it should still work correctly.

i tried swapping two hot-swap sata drives between two nodes in a
cluster, but it didn't work: after restart, one of the datanodes shut
down since namenode said it reported a block belonging to another
node, which i guess namenode thinks is a fatal error. is this caused
by the hadoop/datanode/current/VERSION file having the IP address and
other ID information of the datanode hard-coded? it'd be great to be
able to do a manual gross cluster rebalance by just physically
swapping hard drives, but seems like this is not possible in the
current version 0.18.3.
