Choosing A Webhost:
A web hosting service is a type of Internet hosting service that allows individuals and organizations to provide their own website accessible via the World Wide Web. Web hosts are companies that provide space on a server they own for use by their clients as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center, called colocation. more...

Hi all.
I have a Java application that it connects to the PostgreSQL database with
IPv6 patch installed.
What exactly do you have for the URL in the first argument to
getConnection? If you have a direct IPv6 address like
jdbc:postgresql://::1 it will not work at the moment because it tries to
parse the url using the colon as a delimiter which works fine for IPv4
addresses, but not IPv6 see org.postgresql.Driver#parseURL for more info.
What happens if you are using a name that resolves to an IPv6 address?
You're probably the first person to actually try this. I will look into
this further, but it may take me a while to get IPv6 up and running on my
machine.
Did you get it working yet?
Kurt
The following patch allows you to connect using an IPv6 address by
enclosing it in square brackets.
jdbc:postgresql://[::1]:5432/dbname
Additionally some minor cleanup to JDBC docs, adding <acronym> tags,
mentioning JDBC 3 support, and cross referencing the installation
instructions.
