With the explosive expansion of linked gadgets and most effective such a lot of IP addresses to head round, the cyber web as we understand it will have floor to a halt a couple of years in the past. Thankfully, IPv6 arrived simply in time to rescue the International Extensive Internet.

Earlier than I discuss why IP addresses are so essential for the way forward for your online business (and the cyber web), let’s again up a little bit…

In 1798, English cleric and student Thomas Robert Malthus argued that exponential inhabitants expansion and mathematics meals provide would result in catastrophic effects for the worldwide human inhabitants.

In different phrases, other people would quickly outgrow their meals provide and get started wars.

Not up to 200 years later, we narrowly escaped an international disaster of Malthusian proportions because the International Extensive Internet ran out of IP addresses.

This used to be in part led to via the exponential expansion of gadgets difficult their very own IP cope with and just a restricted provide of addresses being to be had.

Fortunately, this tale has a cheerful finishing, as a number of generation Jedi controlled to intrude simply in time and save us from coming near near doom.

This, then, is the tale of IPv6 and the rescue of our on-line world.

On this publish we quilt:

IPv6 introduction with special effects.

IPv6: What’s it and Why Do You Want it?

An cyber web protocol (IP) is the algorithm governing how packets are transmitted over a community.

IP addressing calls for that each node of an Web Protocol community (e.g. a pc, router, or community printer) be assigned an IP cope with for every community interface.

This IP cope with is then used to find and determine the node in communications with different nodes at the community.

Translated from Aurebesh, this principally implies that each software on the net wishes an IP cope with to speak to every other software.

A No longer So Lengthy Time In the past, In A Galaxy No longer So Some distance, Some distance, Away…

When the cyber web used to be first conceived, no person may just foresee simply what number of gadgets would finally end up having to speak to one another.

Till lately, IPv4 used to be the core protocol used to staff and transmit information over the Web and it nonetheless routes maximum Web site visitors as of late.

IPv4 makes use of a 32-bit cope with area, then again, which limits the selection of distinctive hosts to only beneath 4.3 billion addresses.

Example of an IPv4 address.
An instance of an IPv4 cope with.

The Downside: No Mounted (IP) Cope with

Now, 4.3 billion IP addresses will have seemed like so much when a thousand million nonetheless intended one million thousands and thousands (no longer 1000 million!), however believe this:

Out of the ones 4.3 billion IPv4 addresses, huge blocks had been reserved for special uses and had been unavailable for public allocation.

So, proper off the block, the block of publicly to be had IP addresses used to be already reduced to about 3.7 billion IP addresses.

Traumatic this downside is IPv4 address exhaustion, a situation the place the depletion of to be had IP addresses were expected for the reason that Eighties, when the commercialization of the cyber web started in earnest.

A number of elements have annoyed this depletion, reminiscent of:

  • The inefficient allocation of way more addresses to organizations than in reality required.
  • The global expansion of cyber web connections which might be at all times lively and not switched off (e.g. broadband cyber web get right of entry to).
  • And most importantly, in fact – the expansion of cell gadgets.

Cellphones are like some other software on the net, and in addition require an IP cope with with a view to communicate to different internet-enabled gadgets.

You’ll be able to in an instant see what the issue with IPv4 is while you believe the truth that 4.78 billion people have a mobile phone.

So, already other people have extra cell phones as of late than there are distinctive IPv4 addresses to be had for his or her gadgets.

Take that with a pinch of salt and a grain of Malthus and also you’ve were given a whiskey dangerous recipe for crisis.

Users Worldwide That Own Mobile Phones
Customers international with cell phones. Supply: https://www.bankmycell.com/weblog/how-many-phones-are-in-the-world.

Now, upload the entire ‘good’ gadgets within the IoT (Web of Issues) global that want their very own IP cope with too, and you’ll be able to see now why the International Extensive Internet will have simply been wiped out via IPv4 cope with exhaustion (I’m fatigued simply writing about it).

And to assume that Malthus used to be most effective nervous about people operating out of meals.

Had he lived every other 150 years or so, he can be severely tossing and handing over his sleep as thousands and thousands of long run wannabe social influencers had been selfielessly denied get right of entry to to the ultimate to be had IP addresses.

Then, the entirety modified…

The Resolution: IPv6

The predicted scarcity of IPv4 addresses ended in the advent and adoption of a number of new applied sciences, together with network address translation (NAT), Classless Inter-Domain Routing (CIDR), and IPv6.

Notice: For those who’re questioning “whatever happened to IPv5?” (and IP variations 0 to three…).

Even supposing IPv5 used to be evolved as a way of streaming video and voice information, and serving as a basis for the improvement of applied sciences reminiscent of voice-over-IP (VoIP).

It by no means become an respectable protocol as it used the similar 32-bit addressing as IPv4 – this means that it might have suffered with the similar 32-bit boundaries.

Successfully, IPv5 ran out of steam as IPv4 become exhausted.

So far as the opposite IP variations pass, according to Wikipedia, IP variations 0 to three had been experimental variations (in step with Wookieepedia, then again, the IPv1 is an Imperial patrol vessel designed to be very rapid and maneuverable, nice for preventing pirates, however it lacked a hyperdrive).

However I’ve digressed, so let’s get again on direction…

The IPv6 protocol makes use of a 128-bit cope with and has 8 segments separated via colons of 4 hexadecimal digits that may be any hexadecimal worth between 0 and FFFF.

Even supposing you assume the above sentence appears like Astromech Binary, you’ll be able to inform simply by having a look at an IPv6 cope with that it’s a lot larger and extra tough than IPv4…

IPv4 vs IPv6 … BeeYoop BeeDeepBoom Weeop!

How a lot larger is IPv6 than IPv4 you ask?

In case you had been to distribute $4.3 billion to every man, woman, and child in Canada, they’d get lower than $120 every. That’s pish-posh dosh. So…4.3 billion? Pffft.

IPv6, then again, with its 128-bit cope with area lets in for, stay up for it…(stupidly large quantity alert:)  340 undecillion distinctive IP addresses. We’re speaking about 340 trillion trillion trillion IP addresses.

“In case you had a task that paid you 390 trillion greenbacks in step with hour (US) you would need to paintings 24 hours in step with day, 7 days every week, 12 months in step with yr for just a bit lower than 100 quadrillion years to earn 340 undecillion greenbacks.”

If the theory of incomes that a lot cash makes you uncomfortable, let me put this into point of view:

Consider residing in a Celebrity Wars universe stuffed with a gazillion inhabitable planets the place octillion beings can all message every different’s gadgets (“drink and sit back? I do know this jazz bar in Tatooine”).

Droop for a second the truth that you’ll be able to land on any Celebrity Wars planet, step from your craft with no helmet, and simply breathe usually.

Consider the entire squillions of droids, clones, and good gadgets that will have to exist all the way through the Galactic Empire. How are all of them speaking with every different?

Just a make a selection selected few can transmit packets of data throughout huge reaches of area the use of “The Pressure.” The whole lot else will have to be the use of any other type of transmission protocol.

Heck, we’ve already ran out of IPv4 addresses right here on Earth even ahead of the release of Apple Watch.  And we haven’t even attempted to colonize Mars but.

With IPv6 offering trillions and trillions and trillions of IP addresses to all corners of the Galactic Empire, then again, neatly… that’s an entire different tale.

IPv4 vs IPv6 – Demanding situations

Even supposing IPv4 and IPv6 coexist at the Web (not like stormtroopers and the Riot Alliance), they don’t seem to be interoperable (it’s no longer a made-up phrase – it manner they’re incompatible).

IPv4 and IPv6 can not be in contact with every different however they may be able to coexist at the similar community. That is referred to as Twin Stack.

iPv6 cartoon illustration
It’s Twin Stack…no longer Duel Stack!

The non-interoperability (every other non-made-up phrase to imply incompatible) between IPv4 and IPv6 creates demanding situations when the use of sure packages and protocols.

For instance, IPv6 isn’t well suited with FTP and calls for certain extensions and workarounds for information to switch effectively.

The Advantages Of The use of IPv6

Earlier than we take a look at learn how to arrange your web hosting to benefit from IPv6, let’s take a temporary take a look at one of the advantages of the use of IPv6, and the principle variations between IPv4 and IPv6 addresses.

The principle good thing about the use of IPv6 as now we have simply noticed is having a considerably better pool of IP addresses to be had.

340 billion billion billion billion IP addresses is not anything to sneeze at (there aren’t even sufficient human or Tauntaun noses in the entire universes to do this).

Every other good thing about IPv6 vs IPv4 in step with Lee Howard, is faster speed (no longer somewhat the sunshine pace of the Millennium Falcon, even though.)

Right here’s a few amusing information about IPv6:

  • IPv4 addresses are separated via sessions whilst IPv6 addresses are separated via colons.
  • IPv6 addresses will also be compressed to get rid of main zeros.

Listed below are some examples of legitimate IPv6 (Standard) addresses:

2001 : db8: 3333 : 4444 : 5555 : 6666 : 7777 : 8888

2001 : db8 : 3333 : 4444 : CCCC : DDDD : EEEE : FFFF

: : (implies all 8 segments are 0)

2001: db8: : (signifies that the ultimate six segments are 0)

: : 1234 : 5678 (signifies that the primary six segments are 0)

2001 : db8: : 1234 : 5678 (signifies that the center 4 segments are 0)

2001:0db8:0001:0000:0000:0ab9:C0A8:0102 (This will also be compressed to get rid of main zeros, as follows: 2001:db8:1::ab9:C0A8:102 )
