Kerberos

Good day, everyone!

I work with Kerberos authentication using wireshark to capture packets with information in it.
I want to hashcat Kerberos hashes, but have some problems with the template.

For example
 
Kerberos 5 AS-REQ Pre-Auth etype 23     
$krb5pa$23$user$realm$salt$4e751db65422b2117f7eac7b721932dc8aa0d9966785ecd958f971f622bf5c42dc0c70b532363138363631363132333238383835

This is an example from hashcat website.

The first question: $krb5pa - so in my wireshark traffick the field will be different? or i should leave it in that way?

The second question: $23 - what is this? should i find in packets another value? Look at the attachment, i have maybe different value? should i put 18 in the template?
