An IPv6 packet sent to a Unicast address is delivered to the interface identified by that address.IPv6 addresses are denoted by eight groups of hexadecimal quartets separated by colons in between them. Following is an example of a valid IPv6 address: 2001:cdba:0000:0000:0000:0000:3257:9652
The IPv6 address space is so huge (2 128) that everyone should be able to get a public IP address for every device they will ever own. So theoretically it shouldn't be necessary to have private IPv6 addresses like the 192.168.x.x and 10.x.x.x addresses in IPv4. In IP networking, a private network is a network that uses private IP address space. Both the IPv4 and the IPv6 specifications define private IP address ranges. These addresses are commonly used for local area networks in residential, office, and enterprise environments. Private network addresses are not allocated to any specific organization. Anyone may use these addresses without approval from regional or local Internet registries. Private IP address spaces were originally defined to assist in The IPv6 address space is so huge (2 128) that everyone should be able to get a public IP address for every device they will ever own. So theoretically it shouldn't be necessary to have private IPv6 addresses like the 192.168.x.x and 10.x.x.x addresses in IPv4. Taking up a small part of the massive IPv6 address space, the private IPv6 is for special requirements and private use in IPv6 networks. These private IPv6 addresses are only local to a specific link or site, therefore they are never routed outside a particular network. If you want private IPv6 addresses then you should use Unique Local Addresses (ULA). ULA addresses are not routed on the internet and their advantage is that everybody can generate their own /48 block of which 40 bits are randomly generated so that your private addresses are very unlikely to overlap with somebody else's private addresses. IPv6 adoption is ongoing; according to Google's statistics, between 17.5% and 21.4% of their web traffic is served over IPv6, though IPv6 usage varies significantly among different countries. The principle driver for this new Internet Protocol version is its predecessor's shortage of addresses. Label to identify a network interface of a computer or other network node. Decomposition of an IPv6 address into its binary form. An Internet Protocol Version 6 address ( IPv6 address) is a numerical label that is used to identify a network interface of a computer or a network node participating in an IPv6 computer network and for locating it in the network.

I’m going to be using Unique Local Addresses (ie: private IPv6 addressing), thus my prefix starts with fd; I’m going to use a randomly selected GlobalID (a8:06c3:ce53) and SubnetID (a890) so
The global unicast IPv6 addresses are similar to IPv4 public addresses. These addresses can be used on the Internet. The big difference with IPv4 however, is that IPv6 has so much address space that we can use global unicast addresses on any device in the network. Unique Local. Unique local addresses work like the IPv4 private addresses.
Yes, of course, and they are a looooot more than total IPv4 space. IPv6 allocation is a lot more complex than IPv4, it made for machines and network logic, but IPv4 was made for “compatibility” for human eye. Jul 03, 2017 · Each device on your network has a private IP address only seen by other devices on the local network. But your ISP assigns you a public IP address that other devices on the Internet can see. Here’s how that works and how you can find those IP addresses. Private IPv4 addresses and internal DNS hostnames. A private IPv4 address is an IP address that's not reachable over the Internet. You can use private IPv4 addresses for communication between instances in the same VPC. An IPv6 packet sent to a Unicast address is delivered to the interface identified by that address.IPv6 addresses are denoted by eight groups of hexadecimal quartets separated by colons in between them.
