The addresses assigned dynamically will not be removed from the RBLa IT Centre, unless the applicant is the appropriate person indicated in the WHOIS database. Only a service provider may submit a request to remove dynamically assigned IP addresses.
IP removal will only take place if the address class has changed from the dynamic to static one.
