Adding elements in a Bash array to print them later

I am adding elements on an array (Add a new element to an array without specifying the index in Bash) but I am getting an unexpected result. I suppose I am doing something wrong when adding elements in the array and/or when iterating the array to print its values.

Code:

for name in $(cat list.txt); do
    host $name.$DOMAIN | grep "has address" | cut -d" " -f4
done

for name in $(cat list.txt); do
    echo "."
    IPS+=(`host $name.$DOMAIN | grep "has address" | cut -d" " -f4`)
    echo ${#IPS[@]}
done

for ip in $IPS; do
    echo "IP: $ip"
done

Output:

12.210.145.45
67.20.71.219
75.58.197.10
31.70.88.22

Expected output:

Output:

67.20.71.219
75.58.197.10
31.70.88.22

To iterate over an array, use

for ip in "${IPS[@]}" ; do

See PARAMETERS in man bash.
