IPv6 question
Hi Tomcat community
I'm planning to give a short blurb on IPv6 support in Tomcat at
ApacheCon next week, but as I'm not a heavy Tomcat user, can someone go
over the following information and correct me if I've mis-stated something?
* IP binding is handled by the underlying JRE or via APR if tcnative is used
* If <Connector> only specifies a port, then addresses 0.0.0.0 AND ::
are assumed
* Otherwise, specify address parameter:
- IPv4 as “x.x.x.x”
- IPv6 as “[x:x::x]”
Sample config:
File: server.xml
<Connector port=“8080”
address=“85.195.98.140”
address=“[2a01:7a0:3:200::2:2]”
protocol=“HTTP/1.1”
…
/>
Also, if there are any other points that bear mentioning, I'd be happy
to add them.
Thanks,
Issac

I'm not sure the above applies for APR, I've never gotten it to work (at least not on Windows).
It appears that APR defaults to IPV6 if no address is given. If you look back in this list for about a year to year & a half, you'll see much discussion on this. I am not positive that this has not been addressed yet, as I've resorted to specifying address='0.0.0.0' in all my connectors since I ran into the problem. Give it a test and see.
I think you are correct however for the JRE-based connectors.

I don't think that one can have multiple addresses per <Connector>.
In your example above, you may need two separate <Connector>'s.
<Connector port=“8080”
address=“85.195.98.140”
protocol=“HTTP/1.1”
/>
<Connector port=“8080”
address=“[2a01:7a0:3:200::2:2]”
protocol=“HTTP/1.1”
/>
