The ghostly amount of v6 space is so exciting to see. One day we’ll need to physically route a whole block to another planet — there’s no point using BGP when the ping from Earth to Mercury is 230,000ms at best.

I love IPv6 and it’s so exciting to see it used widely at last. My mobile device is v6 although it’s still dual stack. Home networks are doomed to by v4 forever so your 1990s eToaster can display Yahoo! News! but I wonder how many ISPs are doing 4to6 or CGNAT nowadays? That’s what my cell provider does.

I only know a little bit about BGP. Why does Tesla announce 6x /48s instead of having a /32 of their own and handling their routing internally? https://bgp.he.net/AS394161#_prefixes6

Serious question: why would I want to purchase this as a poster? Asking as a nerd, but maybe not a very specific data oriented nerd.

I agree, it would be much cooler to 3D print it, using the image as a heightmap. Maybe even make 4 separate pieces to increase scale. Preferably in a FOSS 3D printer using home-made plastic, with the models uploaded from a PDP-11 only using the shell.

I agree, but I think it would almost as cool to reproduce the 3D model in Minecraft, hire people to keep it up-to-date in real time, and then project that into your room. Or maybe a stadium.

My ISP to this day still doesn't have dual-stack. It makes a 6rd tunnel available to their users as a "beta" (for years). I find it mystifying to be honest. I know for a fact they have a nice modern facility and an expert head sysadmin. They even have a local fiber optic network. It makes no sense to me that they're clinging so tightly to IPv4.

What is the benefit to the ISP in supporting IPv6 to justify the extra cost of the support?

There is quite a block of multicast addresses in IPv4. Is it used for anything in real life?

Signal distribution (specifically audio and video) uses it heavily with a smattering of different protocols building on RTP. Major examples are things like media production facilities running on SMPTE 2110, live and installed sound systems built around Dante/AES67, IPTV systems in hotels, and network media systems within office environments.

Precision Time Protocol (which many if the above are also dependant on) is also based around it and used across a number of domains where tight clock sync is required.

In considering the rollout of IPv6, end users often get marginalized. This is frustrating to me. When we try to highlight ISPs who refuse to deploy IPv6, mobile services get highlighted - as if homes and businesses could just use them instead of wireline. If that doesn't end the discussion then IPv6 acolytes will go on about transit traffic or anything else until IPv4-only users go away and stop ruining their optimis…

> Personally, I'm very positive about IPv6. I find a lot to like in the protocol Please expand on this (besides ‘wow such large numbers’…). I’ll take my answer off the air.

VMs able to assign themselves an address via SLAAC without involving DHCP is lovely

Some devices coming out now from Google, etc. are IPv6-only and do not support 6rd tunnels at all.

Possible further benefit, reaching India and China who certainly aren't issuing IPv4.

Hopefully the day comes when people can get static IPv6 addresses instead of a dynamic one behind an ISP NAT.

Rollout isn’t a problem for anyone it’s when services start to become unaccessible to IPv4 but accessible on IPv6 end users can get marginalized. We’re still many years from that though which greatly amplifies how much an issue it’ll actually still be when that time comes.

Rollout is still pretty slow: https://www.google.com/intl/en/ipv6/statistics.html#tab=ipv6...

But services supporting it is the other side of the problem. Both need to be addressed.
