UPC ipv6 deployment DS-Lite

K6M2UL

I just signed up as a new UPC customer. I got the T7200 modem. On bootup it appears to have configured itself as native dual stack IPv4 and IPv6. From what I can see the ipv4 nat to a public ip now occurs somewhere within the carrier network and not in the modem. There appears to be no way to configure any kind of inbound ipv4 connection (port forwarding/dmz at the carrier nat, bridge mode doesn't help since the nat is not occurring in the modem).
Am I interpreting this correctly? I get that IPv4 exhaustion is hitting, and i do appear to have native ipv6 access. But it appears It's not possible to run a globally accessible IPv4 service on upc's network. That's not really what I would define as providing an internet service.
I called upc to confirm this as well and they did.
Anyone have any experience with this or suggestions? 4over6 tunnel providers? can I purchase public v4 address from upc? Move to UPC business?
Failing that can anyone reccommend an alternative provider - I care about: a base speed of > 40mb down and at least > 10mb up, a reliable connection - having the modem require a manual reboot or exhibiting any bursts of packet loss are very undesirable, an ipv4 address with a modem that just acts as a bridge. I'm in north dublin city and i believe should be fttc enabled.

Plenty of the country have sub 5MB broadband if any broadband at all. You're complaing because UPC don't give you a dedicated external IP address. Seriously! Many other ISPs don't. Why don't you look at Magnet if you want that. Up to last year I successfully used DDNS to manage external access to endpoints on my internal UPC network. Worked fine for me. You're a bit spoiled if you don't consider 200MB broadband as not acceptable for a service. God help us if you ever move to the countryside!

Its a perfectly valid complaint to have with a fixed line service. Not as much for 3G or FWA but definitely for fixed line.

Don't be so bloody butthurt.

Have you seen this thread on the UPC forum? UPC may be able to assist you.

Thanks that's a useful thread.

There are many axes along which value can be provided for an internet connection. Instantaneous speed is one. Reliability is another. How the Isp peers is another (see the level3 article "'not' neutrality" about us providers intentionally leaving their interconnects saturated). For me personally the value is not concentrated in the instantaneous speed of the last mile connection. There are basic levels of service I expect in these various axes, a globally routable IPv4 address being completely unavailable is below the level of service I expect for a 50-odd euro/month connection. I know IPv4 is running out - Amazon changes 3 euro a month to reserve an ip on their infrastructure - I'd pay that. I was a netsource->magnet customer, and I may well end up moving to them if upc can't provide a solution. Btw DDNS won't help you with DS-Lite.

IPv6 is also a killer blow to smart DNS services.

Interesting - why do you think so?

Just know from expats here in Germany who use overplay and uno telly that they don't work if your ISP assigns you an ipv6 address.

Yeh but there's nothing stopping any of the smart dns providers supporting dns over ipv6 lookups or responses. I guess they'd need to do a prefix match on the ip to cover all the devices in your house.

Hey guys, I recently switched back to upc and I'm using the old cisco router I had previously had in bridge mode.

However now the modem is giving me a ip address in the 10. Range. Is this because I'm on the dslite and using IPV6?

Has anyone seen this before?

Are you sure it's actually in bridge mode? I didn't think the old modems were getting DS-Lite at all. The Technicolor and Ubee ones are though.
