Fixed In Version:
Doc Type: Bug Fix
Doc Text:
Cause: Improper calculation of IPv6 address caused IPv6 addresses that began with leading zeroes to be not be calculated, and those IP addresses would not be assigned. Consequence: Only IPv6 addresses that did not begin with leading zeroes would be calculated. Fix: IPv6 calculation method improved. Result: IPv6 addresses with leading zeroes are calculated properly.
