Problem with a "for"

[tirengarfio]

Hi,

im trying to write a script to check the port 22 of 4 IPs.

IPS={89.17.206.180,89.17.206.185,89.17.206.186,89.17.206.187}

for i in ${IPS}
do
nmap -p 22 {IPS}
done


but i get this error:

Failed to resolve given hostname/IP: {IPS}.  Note that you can't use '/mask'
AND '1-4,7,100-' style IP ranges
WARNING: No targets were specified, so 0 hosts scanned.
Nmap done: 0 IP addresses (0 hosts up) scanned in 0.14 seconds

Any idea?
