--------------------------------------

             Summary: IPv6 is not working on 2a01:4f8:130:2192::2 host
                 Key: INFRA-11567
                 URL: https://issues.apache.org/jira/browse/INFRA-11567
             Project: Infrastructure
          Issue Type: Bug
          Components: DNS, Website
            Reporter: Sylvain Rochet
            Priority: Minor


2a01:4f8:130:2192::2 is the IPv6 address currently set for, at least, http://httpd.apache.org and http://apr.apache.org.

$ dig +short -t AAAA httpd.apache.org
2a01:4f8:130:2192::2

$ dig +short -t AAAA apr.apache.org
2a01:4f8:130:2192::2

IPv4 is working fine but IPv6 hang forever:

$ telnet 88.198.26.2 80
Trying 88.198.26.2...
Connected to 88.198.26.2.

[HANG HERE]

That's a problem, because most browsers don't failback to IPv4 if the IPv6 TCP session is properly established but hang forever. Currently, all IPv6 enabled browsers can't access to anything hosted on 2a01:4f8:130:2192::2 at all
