is the telnet protocol compatible with IPV6? if not what is going to happen to trade wars when everyone changes over from Ipv4? or should i even worry?

Protocols are built up in layers, and each layer is ignorant of the layers above and below it. Telnet doesn't know or care about TCP/IP, just as TCP/IP doesn't care about the hardware layer.

All modern OS have telnet that supports IPv4 or IPv6 addresses.

But what of TWGS support for IPv6? I think that's the real question. The latest version doesn't bind to any IPv6 addresses.

The helper apps would need to be refreshed as well. SWATH for one won't connect to IPv6 hosts/addresses. No one is going to refresh the helper apps to support IPv6 if TWGS doesn't support it.

Are any ISPs suporting IP v6 yet? Mine isn't.

Again, a well-written application does not know or care what version of IP it is using. The IP layer is two layers below the application layer. If an app uses hostnames instead of numeric addresses, it will simply work.

Unfortunately, TWGS forces you to specify its binding interface as a numeric IPv4 address. It may also be hard-coded to use "127.0.0.1" as its "default" interface. Ideally, it would request a list of interfaces from the OS and present them to the user instead of asking the user to input anything. Then it would be properly IP-agnostic.

My point is, that there aren't really any public IPv6 addresses in use yet. They only exist on private LANs.

There are a few. Google launched its IP6 site on June 6.

They aren't the only major site that is moving to IPv6, but until your local ISP supports IPv6 you can't connect to it. I really don't understand why major ISPs like Cox and AT&T are holding us back.

I'll do whatever is necessary to keep TWGS running on IPv6. We discussed this awhile back and decided it's not quite time to take that step. I'm waiting for this to be a bit more urgent.

Uhm, except they are. My connections to Google, Facebook, Netflix, VPN to work, SSH to my colo-hosted servers, and many others use IPv6 natively across the Internet. As of June 6, 2012, dozens of sites permanently turned on their IPv6: http://www.worldipv6launch.org/participants/



Comcast enabled IPv6 service for residential customers (business customers coming soon). If you have Comcast Internet but do not yet have IPv6 connectivity, you most likely need to upgrade your router (and cable modem as well - but if you rent it you can just exchange it for a DOCSIS 3.x one what supports IPv6). From a friend's blog (but I have the same IPv6 from Comcast here as well):

Even if you don't have an IPv6-enabled ISP, you can still get an IPv6 tunnel to Hurricane Electric or SixXS for free to connect to the IPv6-connected Internet.

It'd be nice to see IPv6 support + SSH support added. Thing is, using an IPv6-enabled SSH host would accomplish both, and then just port-forward telnet locally to the TWGS using IPv4.

Google high speed Internet is about to open here in Kansas City, so I'm hoping to have a chance to dabble in "the future" here a little bit. Hopefully that'll give me a chance to explore how TWGS will need to adapt to keep up with changes.

*drool* Have you already got your fiberhood pre-registered so you'll be one of the first to get fiber deployed?

Unfortunately, my area is just south of the southern edge of their starting area, like a mile or two :( But my wife is a doctor with an office in the area and I'm hoping she'll have connectivity. We'll just have to see.

Hopefully, when they expand, we'll be among the first here.

For anyone worried about things not working... there is a "way around" any compatibility issues people might have with ip4/ip6 and it starts with using a router that supports both ip4/ip6.

Basically like my two providers, support ip6, one forces it, the other does not... their modems support one or the other, but with my router, I can support both... and thats the trick to it.

the router acts as the shield for this... my internal network is all ip4 while externally I would appear to others from the router up as an ip6 network... so anyone who does, or will need that buffer for certain software, thats the way.

This is an overkill router for the home user, but I'm certain there are other routers you could grab off the shelf of best buy that do this exact same thing. You can be ip6 to the outside world and ip4 to the inside world so you won't have to make any changes, the router will handle it all for you.

OMG... I just looked at google fiber... they have an option for "free" internet for 7 years minimum... all you have to do is pay the $300 setup... I would so be in on this... no data caps.

sure the speeds aren't glorious but thats a heck of an amazing no monthly price for 7 years! although I know I'd be a sucker for gigabit speeds at $70...

they had me at hello...
