In a makefile, the value of variable is a the name of another variable. How do I get it inside target?

For example:

my_variable := Hello
target:
    @var_name="my_variable" ; 

    result=$($(var_name)) ; 

    echo $$result

The result should be Hello.

Or another example:

VALUES123 := 1 2 3
CLIENTS_1_IP := 10.100
CLIENTS_2_IP := 10.100
CLIENTS_3_IP := 10.100
cll: 
    @for value in ${VALUES123}; do 

        var_name="CLIENTS_$${value}_IP"; 

        echo $$var_name; 

        $(eval CLIENT := $(value $$(var_name))) 

        echo $$CLIENT; 

    done

I need something instead of
