Check the value that you assigned using echo.
$ echo "$IPS"
{89.17.206.180,89.17.206.185,89.17.206.186,89.17.206.187}
Notice that brace expansion hasn't occurred in variable assignment.
In the bash manual it says:
A variable may be assigned to by a statement of the form
name=[value]
If value is not given, the variable is assigned the null
string. All values undergo tilde expansion, parameter and
variable expansion, command substitution, arithmetic
expansion, and quote removal (see EXPANSION below).
Notice that it doesn't say that the value undergoes brace expansion.
This feature originated in csh and csh didn't perform brace expansion
on variable assignment either.
You can do what you want by using echo and process substitution.
IPS=$(echo {89.17.206.180,89.17.206.185,89.17.206.186,89.17.206.187})
However I don't really see the point here. It seems easier simply to
use a normal variable string assignment.
IPS="89.17.206.180 89.17.206.185 89.17.206.186 89.17.206.187"
That seems the simplest and best way to do this.

Again using echo here is very useful.
$ for i in ${IPS}
> do
> echo nmap -p 22 {IPS}
> done
nmap -p 22 {IPS}
You didn't have a dollar sign there. But actually you wanted to
say $i instead.
Hope this helps,
