Node in Default Node category despite of successful host connection




Please help me to understand below issue.



I have discovered few unix server with host connection by shell.


The connection job was successful also its hostname got resolved as per communication log. But still it is showing  its hostname as      " 10.X.X.X_default node" and it is under CIT "NODE" . It is supposed to bein "UNIX " category.



 What could be the cause as inspite of successful connection , other details are not getting discovered. and IP addres doesnot get resolved to hostname.



I have attached communication log herrewith.



with regards,
