IPv6 est le futur de l'IPv4 qui va bientôt saturer son espace d'adressage. Nous allons voir les différences entre les deux protocoles. IPv6 est mieux dans de nombreux aspects, mais il n'est pas compatible avec l'IPv4 qui peut être considéré comme son inconvénient.

IPv4 est vieux et n'a pas été créé avec beaucoup de sécurité. Il suppose que les applications de destinations ont leurs propres mesures de sécurités. Pourtant, il est encore présent en 2017. Mais l'IPv6 est conçu pour rendre le transfert des paquets plus sécurisé. Les choses, comme la vérification de l'intégrité des paquets et le cryptage des données, ont été soudées à l L’IPv4 utilise un espace d’adressage 32 bits équivalant à 4 octets. Cela signifie que le nombre total d’adresses IP sur Internet peut aller jusqu’à 2 ^ 32. C’est à dire environ 4,3 milliards d’adresses. Il est écrite en décimal sous la forme de quatre chiffres séparés par des points. Chaque nombre peut être compris entre 0 et 255. Par exemple, 16.150.10.250 pourrait être IPv4 vs IPv6 - Final Note Whether you run a personal or business network system, it's important to remember that sooner or later, the majority of web companies will make the switch to IPv6 . When that happens, upgrading will be essential if you want to maintain compatibility with … IPv4 vs IPv6: What’s the Difference? Details Last Updated: 13 July 2020 . What is IP? An Internet Protocol address is also known as IP address. It is a numerical label which assigned to each device connected to a computer network which uses the IP for communication. IP address act as an identifier for a specific machine on a particular network. The IP address is also called IP number and

IPv4 IPv6; Size of IP address : IPv4 is a 32-Bit IP Address. IPv6 is 128 Bit IP Address. Addressing method : IPv4 is a numeric address, and its binary bits are separated by a dot (.) IPv6 is an alphanumeric address whose binary bits are separated by a colon (:). It also contains hexadecimal. Number of header fields : 12 : 8 : Length of header Worse still, IPv6 isn't backward compatible so, if you want to run an IPv6 friendly website, you'll also need to maintain an IPv4 version too. Because IPv6 is so uncommon, internet companies are unlikely to start rolling out updates that take advantage of it anytime soon, as only a minority of users will notice the difference. 03/02/2011 · IPv4's successor is IPv6, a system that will not only offer far more numerical addresses, but will simplify address assignments and additional network security features. The transition from IPv4

18/12/2019 · IPv4 has been significantly updated over the years, so the difference between IPv4 and IPv6 security is not extraordinary. The same IPSec in IPv6 is now available for IPv4; it’s up to network providers and end users alike to embrace and use it — so a properly configured IPv4 network can be as secure as an IPv6 network.

The enhancements have been designed so that existing IPv4 applications are completely unaffected by IPv6 and API changes. Applications that want to support concurrent IPv4 and IPv6 traffic, or IPv6-only traffic, are easily accommodated using IPv4-mapped IPv6 addresses of the form ::ffff:a.b.c.d, where a.b.c.d is the IPv4 address of the client. 18/12/2019 · IPv4 has been significantly updated over the years, so the difference between IPv4 and IPv6 security is not extraordinary.
