At ungleich we are already +seeing many things changing and for that reason we start this series +of blog articles about how IPv6 changes the world. + +## The Base Claims + +When starting a series of blog entries about how IPv6 changes the +world, there are some assumptions and general understandings. In this +article we will try to illustrate what we think is already given. + +## Claim 1: Everyone can have IPv6 connectivity + +We know that not every ISP provides IPv6 connectivity yet, but that +is really not a show stopper for IPv6 connectivity. We have even +written an [blog article about how to get +IPv6](https://ungleich.ch/en-us/cms/blog/2019/02/05/how-to-get-ipv6/) +and our conclusion is: **everyone can have IPv6 connectivity**. + +If you are missing options there, give us a shout, we are glad to +add them. Point being, we are very confident saying there is nobody +who cannot have IPv6 connectivity anymore. We even offer +[free IPv6 connectivity to hacker spaces](https://ungleich.ch/u/blog/free-ipv6-vpn-for-hackerspaces/). + +If you very much disagree with us, we are open to be challenged by you. + +## Claim 2: Everyone can host content IPv6 reachable + +If you are in the content or publishing business, you can easily have +your content reachable by IPv6. All bigger +[CDNs](https://en.wikipedia.org/wiki/Content_delivery_network) support +IPv6 and even if you happen to host on an IPv4 only web hoster, +there is +[via-ipv6.com](https://ungleich.ch/u/blog/enabling-ipv4-only-sites-for-ipv6-only-networks/), +a proxy service enabling all your IPv4 content by IPv6. + +And we don't +say you should be using that service, you can also easily build it +yourself: you can use any IPv6 only VM and you can setup a proxy for +yourself. + +## Claim 3: The world is now really moving towards IPv6 + +We know, there was this very, very unfortunate miscommunication many +years ago that we already ran out of IPv4 addresses. That was +only IANA running out of blocks to assign to the RIRs, however the +RIRs +([RIPE](https://www.ripe.net/), +[APNIC](https://www.apnic.net/), +[AFRINIC](https://www.afrinic.net/), +[lacnic](https://www.lacnic.net/) and +[ARIN](https://www.arin.net/)) did have plenty of IPv4 addresses +left. This situation changed since 2011 and now +ARIN is really out of IPv4, RIPE +is likely to run out of IPv4 in 2019. LACNIC and +AFRINIC are soon (probably 2020) to follow. APNIC on the other hand is already having a **per resource +fee**, which let it run out of IPv4 slower. + +But, and there is the big but: APNIC slowing down the IPv4 run out has +a cost. And the cost is for companies who are relying on IPv4 +addresses. So if you are in the APNIC region, you already pay around +1800 AUD for a /22 IPv4 network yearly. + +The situation is somewhat similar in the regions that are running out +of IPv4, only that you need to buy or lease your IPv4 space there from +some market. The price for an IPv4 address is around $25 at the +moment, so if you were to buy a /22 IPv4 network, you would have to +spend more than $25'000. And this is not feasible for most SMB. + +Even if you don't acquire IP addresses directly from a RIR and +run your service on a +[cloud like GCP, you begin to pay more for IPv4 +addresses now](https://news.ycombinator.com/item?id=20742965). + +So what is the alternative? It clearly is IPv6. Not because +there are many IP addresses in IPv6, but because +**IPv6 is affordable**. + +So in short, why the world now really moves to IPv6: + +* IPv4 now becomes a real cost factor +* It is not easy to acquire additional IPv4 space anymore +* IPv6 is economically more feasible +* We take the way of the least resistance, which is now IPv6 + +## Claim 4: IPv6 will re-enable end users + +Due to the long ongoing IPv4 shortage, we are very much used to +[NAT](https://en.wikipedia.org/wiki/Network_address_translation). Some +people even believe that private IPv4 addresses are more secure, +which, generally speaking, is a bogus claim. You still need a +firewall, as you do with IPv6. + +The bigger problem with private IPv4 addresses is that users have been +taught that they cannot reach each other directly. And this eventually +led to the rise of cloud services, because people were unable to reach +each other or to exchange data directly. + +The Internet was built with the idea that everyone can reach everyone +else directly. NAT was only introduced due to the shortage of IPv4 +addresses. + +With the advent of IPv6, there are many "new old" ways of how we can +work together. + +## The changes of IPv6 to the world + +In the next articles we will describe some real, practical changes of +what we use and how we can work differently with IPv6. If you already +have suggestions, we are happy to read them on **ipv6 at ungleich.ch** +or on the [IPv6 Chat](https://IPv6.chat). + +Meanwhile, if you are +interested in giving IPv6 only VPS a try, there is a 50% discount only +until [Black IPv6 +Friday](https://swiss-crowdfunder.com/campaigns/black-ipv6-friday?locale=en). diff --git a/content/u/blog/what-open-source-and-ipv6-have-in-common/contents.lr b/content/u/blog/what-open-source-and-ipv6-have-in-common/contents.lr index ea52c12..042b4bb 100644 --- a/content/u/blog/what-open-source-and-ipv6-have-in-common/contents.lr +++ b/content/u/blog/what-open-source-and-ipv6-have-in-common/contents.lr @@ -1,4 +1,4 @@ -title: What Open Source and IPv6 have in common +title: What was Open Source has now become IPv6 --- pub_date: 2019-11-15 --- @@ -11,28 +11,8 @@ _hidden: yes _discoverable: no --- abstract: -... +The Open Source did not vanish, it just changed --- body: - -## Summary and Outlook - -Centralisation is a danger to everyone.
