how to convert mac address to ip6 address

They should not be used as source or destination addresses.Ī 6to4 gateway adds its IPv4 address to this 2002::/16, creating a unique /48 prefix. It is possible to reverse the process and identify the IPv4 address of the relay server, which can then be looked up in the relevant Whois Database. The address is formed using the Teredo prefix, the server’s unique IPv4 address, flags describing the type of NAT, the obscured client port, and the client IPv4 address, which is usually a private address. This is a mapped address allowing IPv6 tunnelling through IPv4 NATs. Routers must not forward IPv6 packets if the source or destination contains a link-local address. May appear as the source or destination of an IPv6 packet. They do not need to be unique outside of that link. Used on a single link or a non-routed common access network, such as an Ethernet LAN. Reserved for local use in home and enterprise environments (not public address space). However, you can search for the mapped IPv4 address in the relevant Whois Database. One use for this is in a dual-stack transition scenario where IPv4 addresses can be mapped into an IPv6 address. Used to embed IPv4 addresses in an IPv6 address. This often happens when one program sends data to another. This address is used when a host talks to itself over IPv6. This address may only be used as a source address by an initializing host before it has learned its own addresses.
