Should I be running an IPv6 network?

[MacBH928]

I noticed that some people online talking and having their network on IPv6. Is there any advantage to this?

My understanding is IPv6 has failed to pickup for over 20 years and has compatibility problems since a lot of devices dont support it, why would anyone use IPv6?

Right now everyone agrees IPv6 is only good for roger to router communications and everyone believe in NAT routers separating the their network from the Internet! To me IPv6 is not ready for internal Networks!

Well, given it was ratified only 3 years ago (it was still in draft status until then) I'm not sure your 20 year statement holds much water.

For an internal network I see very little use of implementing IPv6, other than preventing ARP poisoning or education.

One thing to all the smart products seem to be only on 2.4 network and current crop of IP6 wireless devices seem not do IPv6!

What does 2.4ghz have to do with IPv6? My Eero supports both 2.4Ghz and IPv6.

so now I stand corrected! However if a computer orInternet smart device needs to be update to at least use the IP5 network(AC) from now on!

IPv6 and WiFi 6 are not the same thing whatsoever.

You seem to be misunderstanding some terms.

IPv4 and IPv6 are protocols used by Ethernet for addressing purposes.

Wireless 2.4Ghz (802.11a/802.11g), 2.4Ghz & 5Ghz (802.11n), 5ghz (802.11ac) and 6Ghz (802.11ax aka WiFi 6e) are methods of providing wireless Ethernet connectivity.

I dont know when it was "ratified" but according to this Wiki they have been talking about it for 25 years.

From the same Wiki you just quoted:

"In December 1998, IPv6 became a Draft Standard for the IETF, who subsequently ratified it as an Internet Standard on 14 July 2017."

You can talk about much, but until a standard like this is ratfied it can be changed.

No-one started why proper rollouts until 10 years ago and even now there's very little need for internal Network implementation for almost all consumers and most SoHo business's where their existing Enterprise addresses are doing fine.

As long as your systems can connect to the outside world then that's all that matters for most people. For most folk ask they need are Operating Systems, Routers and ISPs that are IPv6 capable. Everything else is just gravy.

I’m a retired Network Administration and I help build the Internet that you use today! So don’t tell me I don’t understand!

IPV6 doesn’t use NAT so to use internal IPv6 internally is not smart! To put another way, if you have the Internet smart devices do any of them support IPV6, please point them out!

Hey, you're the one who used "IP5" and "IP6" in your posts - neither of them are official terms. 802.11ac, IPv6 and WiFi-6e are some of the names you should have been using here. There is no such thing as an "IP5" network.

It was your continued misuse of terms that led to confusion. Don't admonish me for correcting you and assuming ignorance of the requisite technology as a result.

And as for the idle boast - that was a rather pointless attempt to impress me - doubly so given your consistent misuse of terminology.

On the internet anyone can claim to be anything. I've been in this game 30 years+ and met way too many self claimed "pioneers".

If your ISP can deliver traffic over IPv6, the big advantage over consumer level IPv4 is that any device on your network can potentially be reached from the Internet. I would say it isn't inherently less secure than running IPv4 behind a NAT - you'll still have a router/firewall in front of your network.

One benefit of being able to route traffic from the Internet to any device, is the freedom to build IoT devices that don't depend on a centralized cloud service to work, where it wasn't necessarily the cheapest contractor who got to decide on security measures for the solution, and where devices may keep working even after some company somewhere decides they aren't making them large enough margins anymore.

So essentially, iPv6 was invented as a proactive measure. ipv4 supply will eventually run out due to the high demand which is when you will see it being adopted widely.

ZDNet - US Department of Defense third attempt to implement IPv6 isn't going well https://www.zdnet.com/article/dods-third-attempt-to-implement-ipv6-isnt-going-well/

First two attempts failed citing security concerns. This time, the DOD is woefully behind on its own implementation plan.
