Does IPv6 have private addresses?
No.
All IPv6 addresses are public
Addresses, even the temporary ones used by ICMP messages, because their. Only purpose is to enable the use of IPv6 routing. They are not for private communications between hosts. In fact, a host generates two different types of private addresses every time it sends an IPv6 packet. One of which is never seen outside the host, and another type that can. Be seen only inside the host. The two types of private addresses are used to ensure both host-to-host isolation and host-to-router isolation. Host-to-host isolation is important for applications such as secure shell. And encrypted communication applications. The second kind of private addresses are the link-local addresses for the purpose of communicating. Within a Layer-2 VLAN. The link-local address is the last of two or more (depending on the implementation) private addresses assigned from the. First 32 bits of an IPv6 address, and the other one that could be reused. By a connected neighbor to exchange configuration information for that. Peer interface or to announce the connected state of that interface to. The network as a router. How will IPv6 traffic pass from my IPv6 enabled server behind the router. Into the network? The link between your IPv6 server and the Internet is carried over your. Normal link, such as the LAN, WAN or dial-up modem connection. It is unlikely you'll notice any difference between how IPv6 and IPv4 data. Traffic looks and behaves since all IPv6 implementations are now at the. IP layer as in IPv4. All IPv6 packets pass transparently from one host on a LAN or WAN to another. If a router has one or more peer interfaces on a LAN or WAN link, a. Multicast based mechanism is used to announce routing information for. That local link and the multicast traffic is carried along with IPv4 or. IPv6 IPv4 packets. For all other interfaces to that router, the router generates the necessary forwarding information and the link-local IPv6. Data packets are forwarded using the same mechanisms as the packets. Traveling to and from the link-local IPv4 subnet. Your IPv6 server at the Edge router has one or more peers.

If you do not have your own IPv6 address and need to communicate with other computers, it is very important that you use a link-local IPv6 address. A link-local address is a valid address for all IPv6 hosts on a given interface. A host can tell whether it is using link-local addresses or not by checking the value of the ::1 IPv6 address in /etc/hosts.
An IPv6-only network is not usable if any host has an IPv6 address but not a link-local IPv6 address. In this case, a connection to a host using an IPv6 address will fail unless the link-local IPv6 address of that host is configured as well.
I do not have my own IPv6 address. Is there some kind of test I can do to find out what IPv6 address I have? Run ifconfig or ipconfig and look for an IPv6 address which looks like ::1. It may be preceded by a zero (for example ::0::1), so you should look for IPv6 addresses that look like ::1.
Check the value of the ::1 IPv6 address in /etc/hosts. This should be ::1 if you have a link-local address. It should be 127.1 if you have a loopback IPv6 address.
Do not worry about the configuration of the address in /etc/hosts. In most cases, only computers on a local network need to use link-local addresses and they will not have a copy of /etc/hosts.
You can use a tool such as ipv6info to see the IPv6 addresses you have. Do I need to configure anything on my router to use my IPv6 address? Usually, IPv6 does not need to be configured on the router that supports IPv6. However, some routers do not support the link-local IPv6 address. For example, many Linux distributions do not yet include support for the link-local IPv6 address in the kernel. To get a link-local IPv6 address on a computer running Linux, you need to set up a link-local address on the computer and also configure the router to forward the packets to the appropriate IPv6 address.
