JDBC Ipv6 address, what is the port number?

Question

I believe there might an ambiguity when using IPv6 IP address
format with JDBC connection address.
A common format for the connection url is:
jdbc:subprotocol:subname
Where:
subprotocol = <some name>
subname = //<{IP Address|Machine Name}[:port]>/<database name>
Example:
jdbc:sql:t9://130.168.200.30:1433/database1
An IPv6 has the format
x:x:x:x:x:x:x:x
where the 'x's are the hexadecimal values of the
eight 16-bit pieces of the address. This is the
full form. For example,
1:2:0:0:5:6
The IPv6 format also allows an abbreviation version where 0's are
replaced with "::". So, the above address could also be written
as:
1:2::5:6
An optional port number can be added. For example,
1:2:0:0:5:6:8888
or as the following if using the abbreviation version of IPv6
1:2::5:6:8888
While decoding this version of the address, an ambiguity arises.
Does the address expand to
1:2:0:5:6:8888 // no optional port number
or
1:2:0:0:5:6:8888 // contains the optional port number.
Is this correct? If so, how are vendors dealing with this?
Thanks,

Is this correct? I am rather certain that you can not create a form that is ambiguous. Ipv4 has either 4 or 5 integers. Where Ipv6 has either 6 or 7.
If so, how are vendors dealing with
this?Realistically the following situations probably exist
- They are not dealing with it.
- The use the functionality in java.net.* and it deals with it.
- They wrote their own stuff which mimics what java.net.* does.
