It's certainly 2 better than IPv4.

Still a meme, gonna take a couple of years to get widespread use.
Greater than ipv4, of course.

it's a fucking travesty we still haven't abandoned Legacy IP and switched over to IP

just my 2cents

Supposedly it's because people are afraid it'd be easier to identify you when it comes to piracy. There are arguments that say that's not the case, but I dunno.

annoying to memorize addresses
I don't use that shit on my LAN

lol you can use literally whatever on your LAN

my isp just assigned ipv6
now all my devices have unique public ip addresses

what do

It'll be easier to switch ip addresses (because availability) and you're less likely to get handed down an ip used by a pedo. Also easier to bypass ip bans.

I swear I've been hearing this shit for 20 years now.

Baka. Tell your isp that unless they'll give you your IPv4 back, you are changing the isp

But why user? Isn't Internet Protocol Version 6 the future?

but i'm stuck with them for the next couple of years

also, they're the only ones here that offer fiber

It'll also be easier to pursue you for whatever bullshit laws some fucks came up with. Not that it's impossible with IPv4, but at least the law enforcement had to put some effort into it so no one really went after some dude who just downloaded a tv show.
In that sense, IPv4 is like captcha from law. They won't do you anything unless you did something really bad.

VPNs exist for a reason.

VPNs are shit

You can always try. Threats don't cost you anything and you always have a non-zero probability of a success.

Dual-stack is in full effect goyim

who said the future would be good?

>and you're less likely to get handed down an ip used by a pedo
...and that's the reason why no one takes IPv4 addresses seriously making it a bit safer to use

Why are all your devices public facing, I'm guessing you did it intentionally? How does that work for security?

I'm used to the IPv4 NAT scenario where you have one public facing device (e.g. a modem or firewall) and the internal network has internal addresses. I know IPv6 has link-local (prefix FE80) addresses for internal network, which are not public.

Apparently IPv6 lets every device have its own public IP address so there's no need for NAT

That could be a problem I guess, I'm not sure how it works out.

elaborate

If everyone watches porn, no one can call you out for watching porn.

it's affords you more privacy, you could change IP per request instead of every hour or after rebooting your modem.

there are already ipv6 firewalls, let me green text it for you
>ipv4
>you have a single endpoint at the modem/router
>all requests are NAT'd using a table in the router
>firewall rules are applied based on the port and address

>ipv6
>you have a block endpoint at the modem/router
>firewall rules are applied based on the port and address

that's it, 99.9% of the time your machine's firewall is not handling internet traffic directly, the modem/router combo still has a drop all rule by default for all internet originated traffic, the difference is you are applying rules to a global address space rather than a internal one.

its shit

With IPv4 law enforcement has to go through isp to identify you, so they don't bother if you are just downloading some pirated animu, but with IPv6 they could go directly to you. That won't probably make them pursue every kid downloading pirated vidya out there, but it will definitely make things easier for them.

What do you think is easier to remember: A bunch of numbers or a bunch of numbers and letters?
10.1.1.1 or 0:0:0:0:0:ffff:a01:101?

>Being this stupid...

Rolled it out a few years ago (Comcast) at home, and a little over a year ago at my company.

There are big advantages in that you don't have to resort to a VPN or the excruciating L4 translations. Dealing with SIP (a protocol that doesn't handle NAT well) is also far more straightforward.

Biggest issue to date has been carriers that are "Tier 1" for IPv4, but nowhere near this for IPv6 - as in they have a single upstream peer and zero diversity.

Microsoft (O365), Google (Youtube), Facebook all rolled out IPv6 years ago, so that is the bulk of the traffic at my office that matters - but if there's a carrier issue, it affects everything.

>what is IPv6 address shortening

So I was looking at my router's IPv6 firewall setup. This is just the same as you'd configure a NAT right?
Another thing, where it says "English" I'm assuming they meant "Remote IP".
>pic related
It's an Asus AC68U if anyone has one and can confirm.

that's not how it works. Open a new tab and search around. You have between 5 minutes and a month to understand how it works and realize how fucking dumb is what you posted. Go ahead, we are timing you shithead.

Trying to encourage colleagues to to start migrating to IPv6 is s fucking nightmare
>it's too hard
>it doesn't make sense
>can't memorize it
Anyone who can't adopt the future of IP is a bad technologist.

it isnt supported enough to matter yet.

try switching over on IPv6 day and see how few things you can get to.

It's entirely plausible, simply by using NAT64 or NAT46 depending on where you need to get traffic to, and what side supports what protocol.

Running dual-stack is completely trivial, and BIND/Tayga make a DNS64/NAT64 implementation almost as trivial.

If you use a smart phone, you've been using IPv6 all day, every day for quite a few years now.

there's no place like ::1

How many times per week are we gonna have this thread?

My opinion on IPv6 is that it's difficult to deploy due to its increased complexity and very different design from IPv4, but once people understand how to use it, it will be for the better.

I mean, IPv4 clearly has no future, so the question is whether you want to push IPv6 or something else (e.g. IPv4-with-more-bits), and I'd say the chances of doing the latter at this stage are virtually impossible.

>what do
Turn on privacy extensions so your devices get random IPv6 addresses instead

this

many ISPs, phone carriers etc. are IPv6-only these days for regular customers, using a combination of ISP-level address pooling or NAT64 gateways

Also, “switching over” to IPv6 makes no sense, because IPv6 is separate from IPv4. Just turn on IPv6 support and be done with it, it's designed to operate in a dual-stack mode during the transition period.

Networking noob here

Could you guys point me to a good, easy-to-understand tutorial or book that showcases what ipv6 has over ipv4?

I don't have enough experience yet to fully understand the offical RFC's.

I don't know of any specific resource that you want, but I found this series very fascinating while trying to learn IPv6 and its upsides and downsides:

See also the follow-ups, it's a 10-part series. Hope you learn something.

Thanks guys, I'll take a look
