Assuming that the site has an IPv4 address. One of the reasons for introducing IPv6 is that internet ran out of addresses; there is not one for everyone. In the years to come, we will see an increasing fraction of DNS entries having IPv6 addresses only. At work, we have so many machines that we have consumed the IPv4 addresses allocated to us, so they have IPv6 addresses only.
Another aspect with IPv4 vs. IPv6: The lack of IP addresses have lead a lot of ISPs to allocate IPv4 addresses temporarily, on demand, to their customers. The address you use today, someone else may use tomorrow. If you offer a service, you have to pay extra for a fixed IP address. Lots of companies dynamically translate a fairly small number of external IPv4 addresses to a large set of internal addresses.
With IPv6 there is no technical need for doing such temporary / dynamic allocations; all devices will (/may) have persistent IPv6 addresses. So if you have looked it up in DNS once, you may keep the translation "forever" in your local cache, and will not depend on DNS again for that address.
This is certainly not by definition; even IPv6 addresses may change (or e.g. a given service is taken over by a different device), but there is far less technical need to update or translate the IP address. Our dependence on DNS stability will be significantly reduced, once static IPv6 addresses are commonplace.
That also means that authorities who want to ban certain web sites will have far less use of DNS censorship; if you have obtained the IPv6 of some illegal site once, you don't need DNS any more. On the other hand: If you had one IPv4 address yesterday, another one two days ago, and a third one today, that would to a certain degree mask your use of dubious services. When you get yourself a fixed IP address, it is far easier to identify the traffic going to you from anywhere along the route, without tracing how your IP address changes over time.

Is that right? Cheers!
I'll give it a try, next time a ping returns an ipv6 address.

Because doing things from scratch after you've learned from past mistakes is more sensible than continuing pretty much where you left off.

Who claims that 32 bit is simple? I know it can be, but when I was teaching elementary computer architecture (as a software man, seeing architecture from a software man to software students) trying to explain the IA-32 mess has kept me forever away from attempting to learn IA-64. I had lost the architecture battle: I was fighting for MC68030 based *nix workstations (so it is long ago!), but the department head overruled the decision preferred by the majority of the teaching and technical staff, demanding that we go for Intel. In my lectures, I did sneak in some examples from non-Intel architectures, but couldn't give the students exercizes on anything but IA-32.
If Intel did a thorough cleanup with IA-64, it might be far easier to understand. I don't know. IA-32 gave me so many frustrations that I never wanted to touch another IA-whatever architecture.
The only thing that is impressive about IA-32 is how they can make that mess spin around as fast as it does. You would think that interpreting hodgepodge of instruction and addressing formats, the MMS and everything, would take so many clock cycles than any other achitecture could easily beat it. The fact that IA-32 essentially knocked down all competiton proves one thing: The hardware implementation guys at Intel must be super clever. I wouldn't say the same about those guys drawing up the x86 architecture. But that was long ago, of course.

politics man (read economics).
they make everything anew so that common people won't know how things work anymore. it is not allowed for people to know all, how the car, the computer, the internet, the washing machine... works. you have time to learn only one thing in life and for the rest of things you can only be a consumer.
that thing moves the business, by making new things that brake how old things work.
and those new things are going to be explained by a mass of new technical abbreviations and acronyms that have almost exactly the same meaning as the old ones, but these are brand new.
and the hipsters are going to love this and show off.
at the same time science is moving in the opposite direction. scientists are trying to discover the unified natural law that explains everything.

Dunno why but something got me thinking about the moonies,
used to be all over the news in the 90's or thereabouts,
these days not a peep.
Did their [superior alien beings] spaceship finally come and pick them up?

Nah ... the leader died in 2012, and there was internal fighting about who took over as the son of gawd.
But it was never a "big church" or even a "big cult" even at its height - 30,000 across the US is less than TV evangelists manage after molesting choir boys and pilfering the offerings tray - it was "hyped" by the media is all I suspect.

I think they hyped themselves too, wasn't it them that married 1000 couples in one ceremony - caused a huge shortage in casserole dishes and toasters at the department stores.

A cult can only be reported on as being a cult until it's big enough to sue you. After that point, it's a bone fide religion.
The art therefore is to thrive on the adverse publicity while you can still get it in order to get to the point where you can't.
People think that prophets have it easy ... they don't.

For them, "big enough" is in terms of money, not membership. The number of members is a minor detail as long as the money is there.

They discovered - using probes of different kinds - that there was no intelligent life to be found here on Earth.
They will probably be back once cats take over as the dominant species... At least this one[^] will...

Ouch! Given where those aliens stuck those probes perhaps they're really not that much smarter.

Well, I dunno. I know a lot of people who seem tho have their heads up their collective asse(t)s. So it could be that the aliens thought they were looking in the right place...

I guess VB/Basic should have become the popular scripting language & not python, if it was envisioned correctly.
The makers of VB had an average vision. I think, they focused much on the visual part. That's okay.
May be the VB*S* should have branched out and gone out to do a lot more things than sticking just with Office automation stuff.
The makers & supporters of python had better vision, now the snake rules the planet.
May be I'm wrong, python might have had its unique strength, from the very beginning.

Visual Basic existed before the internet became into view, and python only existed on some freak Linux box.

"Vision" is marketing-bullshit. VB catered to a lots of hobby-devs, and was used to create a LOT of desktop-applications.

It has. .NET connects everything from Office and your Exchange server to your Database and Azure 
Nand32 wrote: The makers & supporters of python had better vision, now the snake rules the planet.
Due to no free version of VB being available and piracy going down. Python was available for free and could be used without having to create a rich GUI. It was not vision, it was luck.

VB is not a scripting language. VBScript is, and the similarity between the two is approximately the same as comparing Java with JavaScript.

VB lived on as VBA which is a scripting language.

VB and VBA is not the same even though they have common roots.
And VB didn't "live on" as VBA.
VB still exists in more or less the same form as for 20 years ago, whereas VBA is more or less dead.
