The interface identifier created via the EUI-64 process serves as the device-unique portion of the address. This address can then be used by a device to access both local networks and the global Internet.The network prefix and interface identifier are concatenated to make the final (global unicast) IPv6 address.EUI-64 is used to map the MAC address into a 64-bit EUI-64 interface identifier.The MAC address comes from the hardware device.

The leftmost 64 bits of the address come from the network prefix, which defines the network portion of the address.Now that we have seen how EUI-64 mapping works, let’s pause for a bit of a recap and see how the various pieces fit together in IPv6: More importantly, it raises concerns about privacy since it becomes possible to link a hardware device to its online activity. Linking hardware and IPv6 addresses means that changes to one address must force a change to the other.

What are the drawbacks and privacy concerns related to EUI-64?

The large 128-bit address space in IPv6 enabled the mapping of smaller 48-bit hardware addresses into 64-bit identifiers, an option that was not possible with 32-bit IPv4 addresses.ĮUI-64 was created to allow for the easier configuration and administration of IPv6 addresses, allowing computers to get online without the need for manual address assignment or other interventions.ĮUI-64 works by splitting a 48-bit hardware address into two 24-bit parts, inserting a special 16-bit code between them, and changing one bit, resulting in a 64-bit interface identifier.ĮUI-64 enables seamless IPv6 address autoconfiguration, makes it easy to determine a hardware address from an IPv6 address and vice versa, and assists administrators with troubleshooting. However, if this is an issue, we may auto-convert user input.EUI-64 is a special mapping technique that converts common network hardware addresses into interface identifiers that can be used to create IPv6 addresses. We only accept the `AA:BB:CC:DD:EE:FF` variant (not `AA-BB-CC-DD-EE-FF` and other variants existing as well).

**How does this PR accomplish the above?:**Īdd validation for MAC addresses. **What does this PR aim to accomplish?:**Īdd ability to add MAC addresses to define clients immediately connected you the Pi-hole more easily I have squashed any insignificant commits. I give this submission freely and claim no ownership. I am willing to help maintain this change if there are issues with it later. I have tested my proposed changes, and have included unit tests where possible. I have commented my proposed changes within the code. I have made only one major change in my proposed changes. I have r … ead and understood the (), as well as this entire template. **By submitting this pull request, I confirm the following:** In this example, we have the following 'clients' (in the sense of IP addresses): Let me give an example of what I have in mind: They would be (in some way) ordinary clients, so appear everywhere on the dashboard just like the other clients, but they don't really exist. Now, looking at how we can get to what was asked by I had the idea of a new concept: super-clients You can now use a MAC address to apply the per-client filtering to entire devices (as in: network adapters). It brought us very far in improving how Pi-hole recognizes clients. We added a lot of improvements to how clients can be recognized in this thread and I appreciate all the testing, comments and suggestions. It would require a fundamental rewrite of a lot of code for yet low gain in the end.

If we'd record clients in the sense of hardware with one MAC address, maybe even two (WiFi, Ethernet) or more, we'd also have to store the addresses plus which address of the client a request came from. Also because it is an IP address which is expecting the reply to the question. For the DNS server, IP addresses are the only thing it see. Yes, this is a nice summary of why it is not there.Įach client sending requests to Pi-hole gets a distinct record in the memory. It may not look like one, but I find this a very challenging issue because FTL precomputes all the statistics for the individual clients so this seems to complicate things tremendously when you allow them to appear grouped.
