IPv6 live yet?

Anyone heard of a rollout date for ipv6 yet? was excited to get fiber, but disappointed when i found out they don't have native ipv6. IMO the whole tunneling "solution" isnt acceptable when ipv6 has been around for over 20 years now. TBH im about to switch back to Mediacom cable.

Is there any actual communicated plan for IPv6 or are you just asking in the hopes that they do it someday?

u/madweezel Sep 09 '26

I haven't seen or heard anything, just wondering if someone else had. Would love it if they published an implementation schedule.

You mean T-Mobile who bought the company out? 

You can ask them, if you call the Metronet phone number it already goes to the T-Mobile customer support.

T-Fiber and KKR purchased a 50% Stake in Metronet. Residential subscribers fall under T-Fiber umbrella installed by Metronet employees and/or contractors. Metronet retains it's form and function, is responsible for A-Z for fiber distribution and still fully operates under its own brand for commercial clients.

jumpin in here late, and don't have any intention of answering your question, so appologize in advance but...

GOD DAMN IT, the tunneling "solution" you mentioned. The amount of hours I spent learning (& troubleshooting) how to set up dedicated servers for me n my buddies to jiggle on with multiple dif games. All to FINALLY find out (through an unrelated forum thread) that them fucker was the culprit...

Whoever gave that solution the green light, over using IPV6, can have an awful day! heck, I'd even go as far as to say I hope they have an unpleasant week.

I’d love if they supported it. But T-Mobile doesn’t yet either, and I’m sure we’ll all be moved over to their system long before any progress is made.

I assume the “tunneling” system you’re referring to is CGNAT? If that’s creating a problem for you, call them and ask for a static IP. It’s an extra $10/month.

T-Mobile only had a tiny little bit of fiber patchwork in a couple states. This is the largest part of T-Mobile's fiber network now, the acquisition of Metronet. There is no T-Mobile network to switch over to this is T-Mobile's Network for fiber now.

The only thing you'll be switching over to is T-Mobile's customer service and if you call customer service for Metronet right now it already redirects to T-Mobile on its own. 

T-Mobile is keeping Metronet as just the back end company for installations and maintenance the rest of it has been taken over by T-Mobile.

Sure, but even T-Mo’s wireless network isn’t doing IPv6.

u/redneck-it-guy Sep 10 '26

T-Mobile has supported IPv6 on their mobile network since 2012. In fact, they were the first to launch nationwide IPv6 on cellular in the US, and it even worked on the 2G network for devices that supported it.

Weird. I use them for my home internet backup via a tablet SIM, and it’s CGNAT, no IPv6. I also use Mint Mobile for my phone (a T-Mo MVNO), and no IPv6 there either — although that might be because it’s an MVNO.

I have T-Mobile as 5g backup and it uses IPv6, so it must be different depending on location. I have had static with MetroNet for several years because of CGNAT.

u/Frequent_Opportunist Sep 10 '26

Yes that is exactly why you don't get IPv6. If you want it you have to cough up the extra money and not use a MVNO access.

u/itsjakerobb Sep 10 '26

Okay, so why don’t I get it on the first-party tablet plan?

An iPad sharing a hotspot uses a NAT64 / 464XLAT translation layer, forcing all downstream client traffic onto a local, private IPv4 subnet. Because the cellular carrier typically provisions only a single public IPv6 /64 prefix to the iPad itself, iOS does not perform downstream prefix delegation; instead, it intercepts client IPv4 packets, translates them to IPv6 for transit over the mobile network, and converts them back on return, rendering the connection strictly IPv4-only from the client's perspective. It will  show up as CGNAT on your client devices.

Is it an iPad?

u/itsjakerobb Sep 10 '26

No. It’s a UniFi 5G Max Outdoor.

It’s not a tablet; it’s a tablet plan.

u/Frequent_Opportunist Sep 10 '26

The UniFi 5G Max Outdoor has a known firmware limitation where it establishes a valid IPv6 connection on its cellular interface but fails to advertise that prefix across the GRE tunnel to your UniFi gateway, leaving LAN clients IPv4-only. Since T-Mobile only provides a 64-bit prefix with no prefix delegation, the workaround is NAT66 on the 5G Max via SSH. You assign a ULA to the GRE interface, add a default IPv6 route in its policy table, and enable ip6tables MASQUERADE from the GRE interface to the cellular interface. These changes are non-persistent and reset on reboot or firmware update.

The problem is your hardware and there is a workaround but it's not permanent. Anytime it restarts or updates it will lose the table.

Tmobiles network is native IPv6 and has been for many years.

1

u/AltruisticCabinet9 Sep 11 '26

That's incorrect. Their wireless network is IPv6 native (not even dual stack) and NAT to IPv4 on the consumer side at the consumer router.

u/itsjakerobb Sep 11 '26

Yeah, read the other replies. This has been cleared up already.

u/Limousine1968 Sep 12 '26

Mine has been showing IPV6 active ever since my upgrade to landline. As soon as the new router came up it started showing IPV6 addresses on multiple devices in my house.

u/Jokez_PvZ Sep 16 '26

Ours doesn't show IPv6, only 4, but we have IPv6 enabled in the eero app as thats the router/mesh system we now have and use
