I get asked a lot in the comments section “Why should I use IPv6 in my homelab”? And it’s a valid question, IPv4 being the norm in so many networking tutorials and classes, what advantages are there really to v6 anyway?
Well today, I’m going to explain a hypothetical setup with multiple…

Really great video!
Thanks for it!
As someone who used to disable ipv6 on everything, you have converted me.
I started looking at doing your final design at home about 5 years ago but using Docker and found out it's not good for IPv6. Came back here from your Frigate video, unhappy to see it is no better still.
Very nice!
I literally cant even ping the ipv6 address that is assigned to my desktop FROM MY DESKTOP!!! This technology was invented in 1999… its had 25 years to get to a working state…. 25 years for vendors and engineers to implement it. AND YET.. I can not ping my own fucking computer using it!!!!!! IPv6 is useless and worthless and has no application in the real world and that will remain true forever.
websites are working but i am unable to download files from the websites , is any solution for that
Awesome video, very clear, definitely switching to IPv6 for my homelab after watching this, thanks so much!
what are you using for the "explaing" program
My entire ISP does not provide ipv6 in or out. I can't even use it for lan only routing due to modem restrictions.
Very helpful video, although I've used dual stack for all my server's services for a while now.
Could you please make a video with details on your ipv6, where and why you use private/public subnets, how big those are and when and where you use static ips.
Details about your ipv4 to ipv6 layer 4 proxying would also be great (edit: just saw you have a video about that already, amazing!)!
And details how you setup quic and your certificate management as well of course!
Great video!
There's one point I'm not clear about here. You got your IPv6 addresses from your ISP, right? If not, I don't understand how traffic is routed to you from an external IPv6 network (e.g. Verizon mobile)
great presentation, but that brings up some serious security concerns, I guess we will have to rely a lot more on vlans for network segmentation.. I'm very curious about what it's gonna look like in the future..
Ciao, a very useful and clear video, but I am still skeptical about the ipv6. Maybe because of the tons of video and articles: "Hacker paradise", "less secure than.." etc..
To simplify, are you sure that my laptop is still secure with a global address that exposes it from any site and services on internet?
Also if I change the ISP I have to reconfigure all the internal network (static addresses, thier matches on the unbound, etc)
Don't you think that using the ULA and a virtual IP to match the prefix given by the ISP is better?
Saluti dall'Italia 😉
problem solved with a VPN hosted on my router. all clients use local ipv4 addresses and clients outside the LAN automatically connect to VPN.
I'm a simple man. I hear the sound of buckling spring keyboard and I upvote.
If your ISP assigns you a dynamic IPv6 prefix everything breaks because when your prefix rotates you need to change every single DNS record and every single firewall rule.
To me the only problem to solve is how to make the Wireguard devices connect to my home dynamic address peer. That problem is about DNS and it is the same when you have ip 4 or 6. Servers with fixed ipv6 is another story, where your arguments may be applicable. Despite the fact I'm disagreeing: I love your proxmox videos and learnt a lot. Thanks!
What is this green lock in the topology and what is its purpose?
Like most said this was a really great and useful explanation. Thank you.
How do you handle the certificate management with the two different paths?
I'm pretty sure that all the catastrophes that have been happening the world over since 2020 are an effort by the elite to reduce human population. I believe that the main motivator for this is the fact that moving to IPv6 would be so insanely difficult and expensive that, instead, the global elite have decided to reduce the human population in an effort to free up IPv4 addresses so we can avoid the transition altogether.
Are you Italian? It looks like every word you say has a paired hand motion to go along with it.
Is there a matrix that shows you get more clicks or does this translate to more views? Really just curious, I don’t believe you do that in everyday conversation.
Please stop switching the camera's so often. Not just point one second to the screen with the mouse and switch back to see you again. Like i mention before i like your video's but this new stile is getting me crazy !!!
Guys I need help , I want to convert my ipv4 to ipv4/ipv6 , I have 0 clue on how these work , can someone just please help me out, it’s been days I’ve been trying to figure this out, my Wi-Fi customer care doesn’t even seem to care
You may want to think about IPv6 NAT if you have more than routed link. Typically for home users, this might be for a 4g/5g backup provided by the ISP for a landline.
I know you have a video that explains IPv6, but more are always welcome.
I'm still stuck with needing learn how to assign static addresses in a network.
Pls make a video "How U set up your ipv6 homelab"
How service change to ipv6
How to config wireguard
Etc…
Thanks
So what is ipv6 native mean on my router
What if you change ISPs / IPs? On IPv4 NAT takes care of this so if your public IP changes then no device needs to be reconfigured. With IPv6 however you'd have to reconfigure every single device. DHCP wouldn't work either unless you have a DDNS client embedded in every device / service with an IP (not feasible, esp for IoT).
Unless things have changed in the last 5 years or so, IPv6 implementations still haven't been fully completed or standardized. I've tried to set up IPv6 in a couple different environments and I've never gotten it to work properly. Not sure if it's a Microsoft thing, or maybe the specific network vendors I was trying to use (Cisco, Juniper, Palo Alto, Windows server 2016, and Ubuntu 18), or perhaps it was something on the ISP's side, but I was never able to get simple things to work, i.e., being able to ping an IPv6 address inside my network from the internet. I've been working full time doing IT/networking for over 20 years and even with support from the ISP I was not able to get any devices working on v6. It makes a lot of sense for corporations and mobile network operators to use v6 because of the sheer number of addresses needed, but in literally every network install I've ever done it makes no sense. As for split horizon DNS, that is easily fixed by putting your devices which need remote access in a DMZ subnet and let the router do what it was designed to do. No DNS tricks needed. When you host a device on-premises without using a DMZ there's no way to get around hairpin routing if you want to use a single IP for your server/device. IPv4 is getting old and it's not perfect, but it's still FAR easier to work with than IPv6. Maybe when device manufacturers get on board and fully support v6 and ISPs in rural areas get serious about v6 it will be different. For now it's more of a novelty.
IPv6 is kinda like 5G cellular. I am told that 5G has all these great features and can support more bandwidth and connections, but if you live in a state that has terrible mobile connectivity, the number of Gs doesn't really matter. I would absolutely love to be able to make phone calls while driving multiple hours to jobs sites, but most places I drive don't have any cell coverage at all, except by quaint local telephone companies that are 10 years or more behind the technology curve. I guess I've said all this to say that it's all relative. You can upgrade your customer's phones to whatever technology you want, but if they live in an area where you don't want to provide service, it doesn't help them at all. If you provide virtually unlimited IPv6 space to corporations, they'll use it and it will be the greatest thing ever. If you offer those IPv6 addresses to overworked hospital, school, library, etc. IT staff, you're going to have to come up with a damn good reason why they need to renumber their networks for virtually no gains. The people that need IPv6 will figure it out and make it work. The people that don't need it will very likely continue for many more years without it and get by just fine.
But what if you don't want a static unique public ip?
4:00 what application are you using for the diagrams? Looks super helpful!
3:06 what's the app with all the text on your laptop?.
Is it a notes app? With the evernote death, I'm looking for any help possible.
So I lose firewall protection with v6. Not a good tradeoff.
I've been running IPv6 on my home network for over 13 years. Initially, it was via a 6in4 tunnel, but for the last 7.5 years my ISP has provided native IPv6. I get really annoyed at those who claim IPv4 is good enough, especially when they should know better. I just wish people would get their heads out of the sand and move to IPv6. I know a few people whose ISP provides IPv6, but they won't configure their routers to use it. Stupid!!!
That's what bitcoin sv wants to do using ip6 addresses multicast and the blockchain for peer to peer nano financial transactions worldwide for fractions of a penny.
So one thing I'm noticing, is how easy it will be o physically map out my internal network on IPv6. Well, I noticed it a long time ago. There are valid reasons to not use v6. Now, your apparent lack of respect for people that learned the hard stuff long before you were born, is amazing. You think IPv6 is hard for people older than you? You know, the guys on the ground that built it and used it first? Already used it and switched back? Kid, learn to shave your neck, then you might be worth listening to a lecture from.
As a home user, I have no use for IPv6, so I disable it. Less fuss in my systems
How does a private individual own a permanent IPv6 address since these are addresses of all the devices on my network? Is there somewhere I go to buy an IPv6 address block? And how do I get my ISP to route these?
Ipv6 is a failed technology.
Thanks you are the only person that is focusing on IPv6 in the home lab that is making sense. Whenever I post a IPv6 question on forums there is usually a "expert" that will say you don't need IPv6 why bother. Why bother? Because IPv4 NAT really broke how things are supposed to work on the internet and many of the admins and network guys just seemed to forget how great things were without translations. Yes there are new new things to learn with IPv6 such as self configuration, SLACC, RA etc but in the end it so much easier. Also I don't have to run split horizon DNS services anymore. There is one problem of course all those cheap IOT devices that never will use IPv6 we have to account for them and continue to run dual stacks because of that.
