> Everything on my network is going to go through my firewall anyway. I don't want anything on my network to be globally routable. Globally routable ≠ globally connectible. Your (stateful) firewall will still by default block any incoming connection attempts if they are not replies to an initial outgoing connection. It's just that it will no longer be necessary to go through the rigamarole of STUN, TURN, ICE, etc, th…

> Globally routable ≠ globally connectible Tell us with the next 0 day, because that big problem exist, and unfortunately happens every days. IPv6 == All your devices are globally ROUTABLE and CONNECTIBLE from Internet, your home network is part of internet. It is an additional rule in the router's firewall what temporarily avoids it.

I don't even necessarily disagree with you, but your examples don't seem accurate.

Regarding firewalls bring prone to accepting by default, either way the packet has to go through the CPU to be routed. I don't believe there's any inherent bias in the design. You could argue that routers that use a single switch and vlan isolate the wan port are inherently biased, though.

Regarding local hostname resolution, there are several options that don't require your ISP. There's mDNS, DHCPv6 and DNS on your router, ULA prefixes, or you can continue using IPv4 for local traffic.

Yeah I have zero motivation to deal with IPv6. I also have all my IPv4 addresses memorized, and IPv6 addresses are too long to remember with all the hex-double-colon nonsense. If they could have turned 1.2.3.4 into 1.2.3.4.5.6 I'd probably use it, but instead they opted for some scary stuff that looks like d0ff::eefa::0010::faff:::://::92::0 which I'd rather not look at. Product management fail. Anyhow, IPv4 still wo…

You're thinking small.. In an organisation of any significant size, remembering legacy IP is much worse than v6. Chances are you will have lots of disparate legacy blocks, some starting 1.x, some starting 80.x etc. Then you have all the RFC1918 space, and the possibility of overlapping address space in different areas of the business. Then you have to keep track of translations, so an internal address 10.1.1.1 could…

Yeah I get it. At an organization your size, you want IPv6.

I was illustrating why there is zero incentive for 99.99% of people to not care, which is the reason why it isn't getting adopted.

If moving my home network to IPv6 came along with some incentives -- e.g. significant tax breaks, free symmetric gigabit for a year for IPv6 traffic, discounts on rent, tax-free early IRA distributions to buy networking equipment, free electric car charging for 5 years, I'd move to IPv6 in a heartbeat.

Yep I’m in your camp. I have zero problems using IPv4 (and NAT when necessary), unless and until that stops working I’m staying with it.

Newspapers still work.. Why are you here at all instead of writing a letter to the editor of your local newspaper with good old pen and paper? New technology has benefits, if you don't know what they are then you need to learn about them properly. Sticking with old technology because you fear the new is not a good plan.

Because electronic is more convenient.

IPv6, however, is not more convenient than IPv4, so the analogy breaks.

No, it should usually look like v4, except in cases where you're using more address space and need to add more dots. NAT is here to stay, and a LAN doesn't need 128 bits of address space.

Like fd::1? Valid ipv6 that is shorter than an ipv4 address

fd::1 is a reserved address. Did you mean fd00::1?

fd::1 == 00fd::1. The :: expands to fill the available bits with 0

My experience with IPv6. I have option to enable full dual stack with my ISP.

If we’re talking anecdotally, I am running dual stack IPv6 and have had zero issues with Minecraft or any other game on my network on Xbox, Switch, iOS and PC.

Same, my Xbox series x is noticeably faster with matchmaking games. Lobby time and searching for new games dropped from 3 minutes on average to about 45 seconds.

Maybe the addresses wouldn't look so scary if you formatted them correctly.

For example: d0ff:eefa:10::faff:92:0 (though there are currently no addresses in use that start with d.)

Vanity IPv4 addresses like 8.8.8.8 exist because most addresses have been allocated, so companies with money can go hunting for nice ones. There aren't many IPv6 addresses like 2600:: because internet registries don't allocate them on purpose, and I'm not sure if anyone's cared enough to bribe them.

The address can be longer, sure, but it's really near identical to dotted decimal beyond the lengths. I wouldn't mind a simpler DNS server IP though seeing as it's one of the few locations you need to treat as an address regularly.

Do you think we should write addresses like 0000:0000:0000:0000:0000:0000:0000:0001, or what else would you propose?
