If this works on Solaris the same way as Windows then you need do
nothing, it will reconfigure it's local interfaces addresses and resume
processing. I do this every day on Windows. Usually you don't want or
need to get new servers but that is something that we need to consider
for the future. The sites I use right now would not change when I change
locations but only because I'm staying in the same geographical area. On
the other hand if you fly from Los Angeles to London you probably want
new servers. Is this the scenario you are thinking of?
