Hi, (not perfect English incoming)
I have a question to the Netcode (XBL Cloud Serves) H5 use.
Over my ISP I have a native Ipv6 Adress and a Ipv4 Adress over DS-Light, I wonder witch Networkprotocol the Cloud Servers use.
Thanks.
I don’t think such information is disclosed or will be.
A quick google search revealed that some people have had problems when using Ipv6 with H5, so they asked their ISP to change it to Ipv4. I don’t know much about networking, but apparently Ipv6 is not currently widespread.
IPv6 is not required, but may be utilized if available. Teredo and other bridge protocols may or may not be used. Bottom line is your answer is that only IPv4 is required. A;so, you’re likely referring to your external/public IPs, which you have no control over. You can only control the translation between your public and private addresses. If you need help port forwarding or any questions you can PM me

Sorry for the late response, thanks for ur answers.
@thearis420: I “must” use DS-Light, i have not real IPv4 Adress. The Ports are not the Problem.
My IPv6 is lower as my IPv4 ping. 10ms, its not huge but i really wanna know with witch Type i connect to the H5 Server, we all know, v6 is better.

Can confirm. I was switched to IPv6 and couldn’t connect at all, tried various ways of troubleshooting then called my ISP and asked them to change my back to IPv4 and problem solved.

IPv6 will be widespread in a few years, the world is running out of IPv4 addresses(im not kidding)

This is my understanding as well. For anyone that was wondering…
“Teredo is an IPv6 transition technology that provides address assignment and host-to-host automatic tunneling for unicast IPv6 traffic when IPv6/IPv4 hosts are located behind one or multiple IPv4 network address translators (NATs). To traverse IPv4 NATs, IPv6 packets are sent as IPv4 User Datagram Protocol (UDP) messages.”
