I am trying to remove my old ip from my server
It gives error.

C:\Program Files (x86)\Parallels\Plesk\admin\bin>ipmanage.exe -r 46.20.154.36
The IP address 46.20.154.36 is already used for hosting.


mysql> select * from dns_recs WHERE val= '46.20.154.36' ;
Empty set (0.00 sec)


mysql> select * from ip_addresses ;
+----+--------------+-----------------+--------------------------------+--------------------+-------------------+-------+--------+---------------+----------
