Differences between IPv4 and IPv6 – Linksys Official Support
The Internet Protocol version 4 (IPv4) is a protocol for use on packet-switched Link Layer networks (e. g. Ethernet). IPv4 provides an addressing capability of approximately 4. 3 billion addresses.
The Internet Protocol version 6 (IPv6) is more advanced and has better features compared to IPv4. It has the capability to provide an infinite number of addresses. It is replacing IPv4 to accommodate the growing number of networks worldwide and help solve the IP address exhaustion problem.
One of the differences between IPv4 and IPv6 is the appearance of the IP addresses. IPv4 uses four 1 byte decimal numbers, separated by a dot (i. e. 192. 168. 1. 1), while IPv6 uses hexadecimal numbers that are separated by colons (i. fe80::d4a8:6435:d2d8:d9f3b11).

Advantages of IPv6 over IPv4:
IPv6 simplified the router’s task compared to IPv4. IPv6 is more compatible to mobile networks than IPv4. IPv6 allows for bigger payloads than what is allowed in IPv4. IPv6 is used by less than 1% of the networks, while IPv4 is still in use by the remaining 99%.

Everything You Need to Know About IPv4 vs. IPv6
The “IP” in IPv4 and IPv6 stands for Internet Protocol, which is a set of rules that determine how devices transmit data packets across the Internet. Internet Protocol also assigns a unique address to each device on the web. These addresses ensure data packets are routed to the correct device.
What is IPv4?
IPv4 or Internet Protocol Version 4 is the most common protocol for transmitting data packets on the web. IPv4 provides both the identification (IP addresses) for each device on the Internet and the rules that govern how data packets are transmitted between those devices.
With IPv4, a typical IP address has 32 bits and is in dotted-decimal form, like this:
192. 0. 2. 235
Because there are only 232 unique hosts in this decimal format, there are only about 4. 3 billion IPv4 addresses.
What is IPv6?
There’s been a massive increase in devices connected to the Internet in the last decade—with a rise from 5 Internet devices per household to 50 Internet devices per household from 2015 to 2020. This prompted the Internet Engineering Tracking Taskforce (IETF) to create a new Internet protocol, IPv6. It was released in December 1998.
IPv6 addresses are written in hexadecimal format, like this:
The Pros of IPv4 vs. IPv6
Despite IPv6 being the newer, updated IP, there are still many advantages of IPv4.
Existing infrastructure – Most websites use IPv4, even those that also support IPv6. This makes version four a more seamless experience. That is, until most of the Internet switches to version six.
Simplicity – IPv4’s 32-bit dotted decimal is much smaller and simpler than IPv6’s hexadecimal numbers. This simplicity is easier for humans to read.
Support – Because most traffic is still using IPv4, Network operators find IPv4 familiar. They may wait until more traffic is IPv6 before they make any decisions about their own infrastructure—especially if they have enough IPv4 addresses for the near future.
The Cons of IPv4 vs. IPv6
Running short on IPv4 addresses isn’t the only con of version four.
Exhaustion of IPv4 – As we’ve covered, the world is short on IPv4 addresses. This means there’s a cost to buy IPv4 addresses, where IPv6 addresses can be had (in unimaginable quantities) for the cost of registration with a regional registry (RIR). You also pay registry costs with IPv4.
IPv6 Speed – Web and cloud services provider, Akamai, measured the speed of IPv6 vs. IPv4. They found, “Sites load 5% faster in median and 15% faster for the 95% percentile on IPv6 compared to IPv4. ”
Network Address Translation (NAT) for IPv4 – NAT allows a group of devices (usually 10-20) that share a single public IP with IPv4. This requires complex configurations like forwarding and firewall alterations. Because IPv6 has so many addresses, IPv6 devices don’t require additional configuration.
Understanding the IPv4 market
The pros of IPv4, combined with the lack of addresses, created a new marketplace. Today, companies that need IPv4 addresses can buy them through IPv4 Brokers, or a company looking to move to IPv6 can sell IPv4 addresses.
When a company needs more IP addresses, they have three options:
Buy IPv4 addresses – That’s what is here for. Companies can also sell their IPv4 addresses if they’re beginning to deploy IPv6.
Use NAT – As mentioned above, NAT allows one address to be shared among many devices. However, NAT still requires one IPv4 address (usually one per 10-20 people). This has some drawbacks, namely speed issues as packets have to transition paths.
Deploy IPv6 – A business can deploy IPv6, but this may be of limited usefulness until most traffic is also on IPv6. So, even if a business deploys IPv6, it still needs more IPv4 addresses or NAT.
There’s much debate around which is better—IPv4 or IPv6. But really, it’s about your specific needs. If you’d like more information on the differences between IPv4 vs. IPv6, or if you’re looking for help with either, please reach out to us today.
Xbox One will be ‘best experienced’ with IPv6: How do you get IPv6 at …
According to Microsoft, if you want to enjoy the best possible Xbox One gaming experience, you should use IPv6. The Xbox One natively supports IPv6, but finding an ISP that will give you an IPv6 connection to the internet is difficult. By using IPv6 on your Xbox One, you should have less latency when playing multiplayer games, any data that you do transmit over the internet should be safer and more private, and in general any connections made by the Xbox One — either to remote servers, or peer-to-peer — should be faster and more responsive. IPv6 is the successor to IPv4, the address scheme used by every device to connect to the internet (or local network). When you refer to an IP address (192. 168. 0. 101), you are talking about an IPv4 address. The problem with IPv4, though, by virtue of being a 32-bit number, is that it only allows for a total of 4. 3 billion addresses — and there are a lot more than 4. 3 billion internet-connected devices on Earth. We’ve managed to extend the life of IPv4 through NAT (Network Address Translation), which allows multiple devices to sit behind one public IPv4 address, but it’s ultimately just a stop-gap measure. At the time of publishing, both the European (RIPE) and Asia/Pacific (APNIC) regional internet registries (RIRs) have exhausted their supply of IPv4 addresses. Elsewhere, in the Americas and Africa, there’s a few million addresses remaining that should be exhausted in the next few years. [Image credit: ARIN]IPv6, by moving to 128-bit addressing, allows for a grand total of 340 undecillion addresses — that’s 340 followed by 26 zeroes, or more addresses than we’ll probably ever need, even if we manage to populate most of the Milky Way. This means that NAT — which generally slows things down and causes various firewall-, P2P- and connectivity-related issues — can be removed from the equation, instantly (and quite dramatically) improving your internet experience. IPv6 also introduces IPsec, a companion technology that was created for IPv6, backported to IPv4, but which really comes into its own when connected end-to-end via IPv6. Basically, IPsec (IP security) authenticates and encrypts each packet, increasing the privacy and security of your data. IPsec can be implemented in peer-to-peer communications, too (say, between multiple Xbox Ones). For more information on IPv6, check out our full IPv6 the rapid growth of smartphones and other internet-connected devices, ISPs and consumers are finally starting to feel the squeeze from IPv4 address exhaustion — and thus, some 15 years after it was standardized, ISPs are actually starting to switch over to IPv6. With IPv6 routes opening up across the internet, web companies such as Google, Facebook, and Yahoo are turning on IPv6 as well. Still, though, the growth of IPv6 is slow: In October 2012, 1% of Google’s traffic was IPv6; by September 2013, that had risen to to use IPv6 on your Xbox OneIf you want to get the best gaming experience on the Xbox One, you’ll need to find an ISP with a complete IPv6 setup in your area — which is sadly still quite difficult. In the US, most of the major ISPs (AT&T, Verizon, Comcast, Time Warner Cable) are rolling out IPv6, but it’s a slow process, and there isn’t much you can do to speed it up; you’re either on their IPv6 network, or not. Canada, too, is dragging its heels. Outside the US and Canada, there are more options. In the UK, Andrews & Arnold have provided to-the-home IPv6 connections for 11 years. In the Netherlands, hit up XS4All; in Germany, M-net; in France, Free; in Australia, general, especially if you’re in the US, your best bet is probably to check the list of World IPv6 Day participants, which includes links to the relevant IPv6 roll-out/status pages for major ISPs around the world. In some cases, you might be able to poke your ISP to send you a new IPv6-enabled router, if you’re in an area where the ISP’s backbone has been updated to support nally, we should probably discuss the PS4 compatibility with IPv6. While Microsoft has clearly stated that the Xbox One will support IPv6, and the IPv4-IPv6 bridging technology Teredo [PDF], Sony has remained oddly quiet about the PS4’s IPv6 capabilities. I would be very, very surprised if the PS4 does not support IPv6 — but while Microsoft is fully on board the IPv6 train, it’s possible that IPv6 will be more of an afterthought on the PS4, and thus isn’t being advertised. Even so, though, assuming the PS4 hardware and operating system support for IPv6, you should at least see a reduction in latency by moving to IPv6 on your read: Can the Xbox One take over the living room?
