Just because a smartphone can get an IPv6 address from a cellular network doesn’t necessarily mean that its tethering functionality is also IPv6 capable. Fortunately, I’ve noticed in practice that more and more devices that are coming to the market these days have implemented the feature. And here is how it works:
A couple of weeks ago I had a post in which I noted that while I have mobile IPv4v6 connectivity while I’m in my home country, I get IPv4-only connectivity when roaming by default. Now it looks like this is not universally true anymore.
Back in 2009 (!) I described the theory behind how a mobile network assigns an IPv6 Prefix to a mobile device. 3GPP TS 23.221 and TS 23.060 are a good starting point. 6 years later things have moved from theory to practice so I decided to write another blog entry on the topic, this time … Continue reading How To Get an IPv6 Prefix From The LTE Network
Over the past years but particularly in recent months I had quite a number of posts on many different aspects of using IPv6, beginning from IPv6 use at home on the PC to using IPv6 on a server at home. With things now neatly in place on both clients and server it’s time for an … Continue reading Hosting An IPv6 Reachable Server At Home – The Summary
I’m probably one of the few people on this planet who appreciates and uses IPv6 both over my DSL connection at home and also over my cellular connection. Unfortunately there is one thing missing on the mobile side: Unrestricted incoming IPv6 access.
I’m quite advanced in my IPv6 adventures but there has been one thing that has been holding me back so far: The DNS resolver in my DSL router at home refuses to properly return the IPv6 address of my local server. Instead it doesn’t respond at all to this request. As a consequence my web … Continue reading My IPv6 DNS AAAA-Resolver Bug Is A Feature – With A Fix
I’ve written about having IPv6 access both at home and on my mobile devices anywhere now a number of times before but actually, it’s not as universal as that after all because there is one loophole…
In my quest to do as many things over IPv6 now that it’s supported not only by my VDSL line at home but also by my mobile network operator, the last success story I reported here was about how to update my IPv6 DNS entry whenever the dynamic IPv6 address of one of my servers … Continue reading The Mysterious IPv6 DNS AAAA-Resolver Bug
On my way into IPv6 land the next stop was in OpenVPN land and to see if I could establish an OpenVPN tunnel over an IPv6 UDP connection. Note that in this scenario I only want to have IPv4 inside the tunnel as before but the tunnel itself should make use of a UDPv6 instead … Continue reading No Love In Ubuntu 14.04 for OpenVPN and IPv6/UDP for Transport
In a previous post on my first “IPv6 call” to a service at home I reported about the pains of finding a Dynamic DNS provider that supports IPv6 and supports it with a Time To Live (TTL) value of 60 seconds. The later part is important as this is the time the domain is not … Continue reading How To Get That Dynamic IPv6 Address To The DNS Server
