The reason it's a bad idea, is that all your devices are visible to the entire You may be able to ask the ISPįor a static IPv6 address, but that is a bad idea. You can force your computer to use a static IPv6Īddress, but only if it agrees with the ISP. This means that the router does not control the IPv6 prefix which the ISPĬan change whenever it likes. Locally by the router or by each computer and is usually a random value based The first (the prefix) is assigned by the ISP. IPv6 is quite unlike IPv4 in the sense that the long IPv6 address is made up of The section about specifying the IP addresses that the router assigns by MACĪddress does not say whether they are IPv4 or IPv6, but I think it is highly If I'm setting the IP address manually on each device, is there any further configuration that needs to be done (apart from avoiding duplicates), or will the router just accept that device A is going to use its own configured address?Īs you can see above, that's how IPv6 address configuration works anyway.Īnd contains for IPv6 only an option for entering a static IPv6 addressįor the router itself (as received from the ISP). So if you have a DHCPv6-capable client on a DHCPv6-capable network, chances are it'll have both a nice DHCPv6-assigned address and a longer SLAAC-autoconfigured address.

Android does not), so having SLAAC alongside is almost unavoidable. But not all clients support DHCPv6 at all (e.g. That means you can create DHCPv6 address pools, you can configure static address leases in DHCPv6, and so on. That said, DHCP does exist in the IPv6 world and handles address leases in much the same way as IPv4 DHCP does. (Depending on each device's OS, the suffix might be a MAC address in traditional RFC4862 SLAAC it might be a static hash value in RFC7217 it might be completely random in RFC4941 'Privacy Extensions' and it might even be a user-provided value if the OS allows that.)įor example, the router advertises 2001:db8:123:456::/64 as the LAN address prefix client A combines it with its own MAC address and begins using 2001:db8:123:456:6af2:68fe:ff7c:e25c. The router cannot limit hosts to just a specific sub-range in fact the router does not receive any feedback about hosts' chosen address at all. In IPv6 primary address auto-configuration mechanism (SLAAC) is completely stateless: the router does not issue individual addresses it only periodically advertises the subnet address prefix and each host just combines it with its own chosen suffix. Overall, the process in IPv6 is usually completely different. The usual terms are 'static DHCP lease' or 'DHCP reservation'. This usually isn't called 'manual configuration' to avoid confusion (from the LAN hosts' point of view, it is still automatic configuration). No configuration is done outside of the router Here are IPv6 Ranges you can browse all ranges of each IPv6 network addreses from start to end IP.To clarify with how I manually set network IP addresses, my router has a page where I can set an address of my choosing to a MAC address. Two colon characters (::) can also be strung together to shorten notation and eliminate groups of zeroes.

Although IPv6 addresses are 4 times as long as IPv4 addresses, IPv4 addresses can still be written in IPv6 notation.

IPv6 IP addresses are 128-bits in length. This tool is provided by the help of IP Find. Here are IPv4 Ranges you can browse all ranges of each IPv4 network addreses from start to end IP. Each address is 32 bits in length and the 32-bit address is broken up into four 8-bit octets. This is the most common notation for IPv4 addresses. Following we defined only format of IPV6, IPV4 and integer IPv4 address format IP addresses can be represented in several different ways, including IPv4, IPv6, integer etc.
