We can leave the space after the IP address. That will not matter for the ssh command.
Code:
sed "s/ \([0-9.]\{1,\}\)@\([^ ']*\)/ \2@\1/ ; s/ @/@/"  file

GNU sed -r; BSD sed -E:
Code:
sed -E "s/ ([0-9.]+)@([^ ']*)/ \2@\1/ ; s/ @/@/" file

Code:
alias server.domain.com='ssh user1@192.168.1.1 '
alias server1.domain.com='ssh user2@192.168.1.1'
alias server1.domain.com='ssh user3@192.168.1.1'

It won't take core of switching the order on the first line, but the extra space problem can be resolved simply with:
Code:
awk '{print $1,$2,$3 $4}' file
