No need to put the host in backticks though, you already have that value locally.

Code:

host="10.72.169.$i"
server=`ssh -o ConnectTimeout=3 root@10.72.169.$i 'hostname'`
release=`ssh -o ConnectTimeout=3 root@10.72.169.$i 'cat /etc/redhat-release'`
echo "$host $server $release" >> result

Running two ssh:s to run two commands in sequence still seems very wasteful, but if you can't get it to work with both commands in the same ssh command line, I guess that's inevitable.
