If your IPv6 does not start with “fe80”, then you can enter the following command to connect to an IPv6 address. ssh
IPv4/IPv6 subnet calculator and hierarchical IPv6 addressing plan builder This is the online version of GestióIPv3's embedded subnet calculator. GestióIP is a free, web-based IP address management software. To calculate an IP address select the IP version, introduce an IP address, choose a bitmask/prefix length and click "calculate". Jun 12, 2018 · Therefore, when an IPv6-enabled system is connected to a network, it will configure itself with a Layer 2 address in the fe80::10 address range based on its MAC address and will listen to the fe80::/10 Example: fe80::200:5aee:feaa:20a2 Prefix Designation and Explanation IPv4 Equivalent Unspecified This address may only be used as a source address by an initialising host before it has learned its own address. Loopback This address is used when a host talks to itself over IPv6. This often happens when one program sends data to another. そのため、通常、IPv6ホストは、IPv6対応の各ネットワークインターフェイスに複数のIPv6アドレスが割り当てられる。リンクローカルアドレスは、近隣探索プロトコル(NDP)のIPv6サブレイヤ操作や、その他のIPv6ベースのプロトコル（DHCPv6など）に必要となる。
Any IPv6 adapter should always have two IP addresses if you're using it for internet traffic - your link-local address and your global address. Your global address is world-routable, so anyone anywhere in the world can see that IP address (although of course, there should be a firewall between you and them to stop them from actually accessing you).
Jul 26, 2019 · I think this is because the IPv6 fe80::1%xx is in the DNS Server address list on client computers. When I disable IPv6, that address goes away from DNS Server address list and then the name servername.domain.local is resolved properly over IPv4 and everything works perfectly. IPv6 is making room. Everything that connects to the Internet has to have its own unique Internet Protocol (IP) address. Think of an IP address as a phone number that websites and devices use to communicate with each other.
Example: fe80::85d:e82c:9446:7994/120 will have an associated net/subnetmask containing 120 contiguous bits. Returns. true: If the long representation of the first IPv6/IPv4 string argument is equal to the second IPv6/IPv4 string argument. false: Otherwise. null: If conversion for one of the two IPv6/IPv4 strings wasn't successful.
Gain insight from IPv6 expert Jeff Harrington, who also gave us an overview of IPv6 in this free webinar. Most organizations haven't made the transition from IPv4 to IPv6: According to our annual survey, only 10 percent of IT professionals reported having transitioned to IPv6, with 34 percent unsure of when they'll transition. IPv6 Link Local addresses are identified among IPv6 addresses by reserving the left most 64 bits as 1111111010000000 0000000000000000 0000000000000000 0000000000000000 (translates to FE80 in hexadecimals). IPv6 Link Local addresses are used by devices for communicating with other nodes on the same link. Auto-Address Configuration is done automaticaly with the help of Link Local Prefix (FE80::/10) and Interface Identifier in EUI-64 Format. This is the widely used method to configure a IPv6 Link Local Address. The second way is Manual Configuration. In this configuration way, we use a manual router command to configure IPv6 Link Local Address.

Think of an IP address as a phone number that websites and devices use to communicate with each other. Apr 28, 2011 · IPv6 link-local addresses are a special scope of address which can be used only within the context of a single layer two domain. Packets sourced from or destined to a link-local address are not forwarded out of the layer two domain by routers.
