IPmanager checks that IP addresses can be allocated to servers again.

The verification consists of two steps:

  1. Verification of IP address for physical accessibility on the network.
  2. Verification of IP address for the presence of DNSBL blacklists.

Learn more in IP address testing. If the IP address did not pass the verification, it will be added to the list in Statistics → Problem IP addresses.

Possible problems:

  • the address is already used in the network;
  • the address is blocked by DNSBL.

Click Unlock to forcibly release the IP address. The IP address had the status "Blocked by DNSBL", the status will be changed to "Available".
