( source ) i totally agree. (and this is probably why i’ve never heard or used it before.) but since i’m not a quitter i went on and tamed it. so, in this article i’m going to shed some light on this mysterious design pattern. read more → sebastian krysmanski • articles , code project , software development • c# , design patterns , method dispatching , oop , visitor pattern ipv6 address primer january 1, 2018 • one comment almost all developers know that ipv6 solves the problem that we’re running out of (ipv4) ip addresses – by having “longer” ip addresses. but that’s only a part of what ipv6 addresses really mean. so, in this article i’m going to shed some light onto these other parts. table of contents [ hide ] 1 notation 1.1 uniform notation for humans 2 special addresses 3 subnet prefixes and interface ids 4 scopes 5 automatic address configuration 6 slaac 6.1 privacy extensions 7 percent notation for link-local addresses 8 unicast, anycast, multicast 9 well-known address prefixes notation ∞ ipv6 addresses consist of 128 bits (whereas ipv4 addresses are only 32 bits long). these 128 bits are written in hexadecimal notation as 8 blocks with 16 bits each. blocks are separated by : . 2001:0db8:0000:0000:0000:0000:0000:0001 this is the full notation of an ipv6 address. however, to make the addresses (potentially) easier to read or write for humans, rfc 4291 allows for some abbreviations. first, one can omit all leading zeros. 2001:db8:0:0:0:0:0:1 furthermore, consecutive blocks of zeros can be abbreviated at most once with :: . 2001:db8::1 note that :: can be the start of an address. for example, the address for localhost is ::1 . uniform notation for humans ∞ unfortunately, the rules for writing ipv6 addresses as defined in rfc 4291 (see above) are not ideal for human consumption – as none of the two rules are required. fortunately, there is also rfc 5952 which contains rules to make the textual representation of ipv6 addresses consistent and “easier” for humans to read and write. the rules are as follows: leading zeros must be omitted. 2001:0db8::001 2001:db8::1 the :: must always shorten as much as possible . 2001:db8:0:0:0:0:0:1 → 2001:db8::0:1 2001:db8:0:0:0:0:0:1 → 2001:db8::1 the :: must not be used to shorten just one zero block . 2001:db8:0:1:1:1:1:1 → 2001:db8::1:1:1:1:1 2001:db8:0:1:1:1:1:1 → 2001:db8:0:1:1:1:1:1 if there are multiple abbreviations possible with :: (all with the same length), then the left-most one must be used. 2001:db8:0:0:1:0:0:1 → 2001:db8:0:0:1::1 2001:db8:0:0:1:0:0:1 → 2001:db8::1:0:0:1 all letters must be lower-case . 2001:db8::1 2001:db8::1 if a port number is attached to the address, the address must be enclosed in angular brackets. 2001:db8::1:80 [2001:db8::1]:80 special addresses ∞ there are two special addresses in ipv6: ::1 is the loopback address (equivalent to 127.0.0.1 in ipv4). however, unlike in ipv4, there’s only one loopback address (whereas in ipv4 you have many – i.e. 127.0.0.1 to 127.255.255.254 ). :: is the unspecified address (i.e. all blocks are zero). this address must only be used under certain circumstance – mainly before a network adapter has gotten an ipv6 address. subnet prefixes and interface ids ∞ a subnet prefix (or just prefix ) defines the size of a subnet in ipv6 (like in ipv4). its length in bits is appended to an address with a / . 2001:0db8:0000:0000:0000:0000:0000:0001/48 in this example, the prefix length is 48 bits (the first 3 blocks). this means that the subnet “size” is 80 bits ( 128 - 48 ). as for the terminology, rfc 4291 calls the two parts of an ipv6 address subnet prefix and interface id . for the address from the previous example, this means: | subnet prefix | interface id | +-------------------------------+------------------------------+ | 48 bits | 80 bits | +-------------------------------+------------------------------+ | 2001:0db8:0000 | 0000:0000:0000:0000:0001 | +-------------------------------+------------------------------+ the interface id uniquely identifies a network adapter (nic) within its subnet. ipv6 requires that a subnet is at least 64 bits big (or that a prefix is at most 64 bits long). exceptions can be made but then some ipv6 features (like slaac ) may no longer work properly. the prefix length for globally routable addresses (see next section) is controlled/specified by the isp. unfortunately, it’s not uncommon that an isp gives just a 64 bits prefix – meaning that you can have just one subnet . an exception to this minimum network size rule is the loopback address. the prefix of the loopback address is 128, meaning the “subnet” consists only of one address. ::1/128 scopes ∞ each ipv6 address has a scope. the scope says where the address is valid. the most important scopes are: scope prefix length description host 128 only valid on the host; used by ::1 link-local 64 only valid on the link (i.e. up to the next router) global 64 ( source ) valid globally one important note on the global scope: in ipv4 you usually had one public ipv4 address (provided by your isp) and the ip addresses of each device on a local network were “hidden” behind a nat. to make a device reachable from the internet, you had to create a port forwarding. with ipv6, if a device has an address with scope global , this device is reachable from the internet under this address (unless the router has a firewall to prevent this – which it should have). automatic address configuration ∞ with ipv4 you need a dhcp server to automatically assign ip addresses to devices (unless they have been configured with static ip addresses, of course). with ipv6 this is no longer necessary (although it’s still possible). as described before, an ipv6 address consists of a subnet prefix and an interface id . so you need to know both to construct an ipv6 address. for link-local addresses, the subnet prefix is always the same: fe80::/64 (some documents say fe80::/10 but the prefix length is effectively 64 bits ). so, an ipv6 device only needs to generate its interface id . the interface id is usually based on the network adapter’s mac address and is usually formed by a process called “modified eui-64” (see rfc 2464 for more details). for global addresses, slaac is used (see below). to make sure that the generated ip address is really unique (both for global and for link-local addresses), an ipv6 device will “ask” the network whether this address is already taken (via dad – duplicate address detection) before actually using it. slaac ∞ to automatically generate an ipv6 address, a device needs to know the subnet prefix of the subnet for which it wants to generate the ip address. while the prefix for link-local addresses is fixed, it is not fixed for global addresses. to figure out the subnet prefix for a global address, an ipv6 device uses slaac ( s tate l ess a ddress a uto c onfiguration). simply put, through slaac an ipv6 device can automatically determine the router of a link and ask the router for the global subnet prefix. the interface id can then be generated the same way as for link-local addresses. nowadays, however, the privacy extensions will be used instead. privacy extensions ∞ as mentioned above,
