Address ranges entered for the `AllocationPools` IPv6 networks and IP allocation pools must be input in a valid format according to RFC 5952. Consequently, invalid entries will result in an error.
As a result, IPv6 addresses should be entered in a valid format: Leading zeros can be omitted or entered in full, and repeating sequences of zeros may be replaced by "::".
For example, an IP address of "fd00:0001:0000:0000:00a1:00b2:00c3:0010" may be represented as: "fd00:1::a1:b2:c3:10", but not as: "fd00:01::0b2:0c3:10", because there are an invalid number of leading zeros (01, 0b2, 0c3). The field must be truncated of leading zeros or fully padded.
