We had the problem that the ip we removed remains in the user domain files. This is what we did:
1) Gave a reseller a dedicated ip
2) Gave a user his own dedicated ip
3) Set that to the main ip for the user
4) Later on decided to remove the ip from the user
5) Freed the ip in IP Management
After this the dedicated ip remained in the file(s) /usr/local/directadmin/data/users/<user>/domains/mydomain.com.ip_list
