hash-identifier md5crypt?

[pay]

hey every1,

i am trying to crack an encryption,i am trying to understand what encryption is that, i know its an md5crypt but i want to know which one,  when using jtr its telling me its md5crypt 256 AVX2, when using hash id unknow , hash-identifier its telling me only md5 (UNIX) and when using online hash id or hashcat its telling me its md5crypt only the encryption is 

<REDACTED>

i want to know what command do i need to use to crack this

what i am using right now is

Code:

-m 500 pass.txt --increment --increment-min=1 --increment-max=10 --custom-charset1=?d?l -a 3 ?1?1?1?1?1?1?1?1?1?1

i tried other combination (like ?1?1?d?d?d?d?d?d?d?d and so on) with no luck, i am not sure this is the right atack that i need to use on this.
my feeling is i am doing somth wrong

thanks ! and have a wonderfull day
