Cause: IPv6 addresses should be expressed either with no leading zeros, or with enough leading zeroes to pad out the full address.
Consequence: If an IPv6 is supplied with only some of the leading zeroes, this will cause the IP address to be interpreted incorrectly.
Workaround (if any): Always use full leading zeroes, or do not use leading zeroes. For instance, the IPv6 address 2001:db8::1 may also be expressed as 2001:db8:0001, but 2001:db8:01 will fail.
Result: You must pay attention that IPv6 addresses are specified in the above way, or deployment may fail as a result.
