Packets sent to an IPv6 unicast address are delivered to the interface identified by that address.Ī global unicast address cannot be the same as its network prefix because an IPv6 address which is the same as its network prefix is a subnet-router anycast address reserved for a device. Since each interface belongs to a node, the IPv6 unicast address of any interface can identify the relevant node. Instead, a multicast address can be used as a broadcast address.Īn IPv6 unicast address identifies an interface. Unlike IPv4, there is no broadcast IPv6 address. IPv6 addresses can be classified as unicast, multicast, or a new class called anycast. Taking the insertion of a hexadecimal number FFFE (1111 1111 1111 1110) into the middle of a MAC address as an example, see Figure 7-1 for the detailed conversion procedure. For Eth-Trunk interfaces and its sub-interfaces and VLANIF interfaces, the EUI-64 address is generated based on the MAC address of an interface, with FFFE added in the middle.For loopback interfaces, VBDIF interfaces, and tunnel interfaces, the EUI-64 address is generated based on the MAC address of an interface, with the last two bytes following the interface index added in the middle.To address stacking conflicts, the EUI-64 address of a Layer 3 physical interface or a Layer 3 sub-interface is generated based on the MAC address of the physical interface, with the last two bytes following the interface index added in the middle. Different Layer 3 physical interfaces may have the same MAC address.If the interface has not been configured with a MAC address, the EUI-64 address is generated based on the following rules: If the interface has been configured with a MAC address, the EUI-64 address is generated based on the MAC address of the interface, with FFFE added in the middle. The 64-bit IPv6 interface ID is translated from a 48-bit MAC address by inserting a hexadecimal number into the MAC address, and then setting the U/L bit (the leftmost seventh bit) to 1. This address is derived from the link-layer address (such as a MAC address) of the interface. The 64-bit interface ID in an IPv6 address identifies a unique interface on a link. Generating an interface ID in EUI-64 format is the most common practice. You can manually configure the interface ID, generate it through system software, or generate it in IEEE 64-bit Extended Unique Identifier (EUI-64) format. Interface identifier (interface ID): Corresponds to the host ID of an IPv4 address. They are very friendly and quite helpful.Network prefix: Corresponds to the network ID of an IPv4 address. Lastly, if none of these solutions work for you, I recommend contacting customer support. I’ve found that setting up a DNS filter under LAN settings can eliminate leaks and help avoid proxy errors. If your IP address shows in a DNS leak test, you won’t be able to unblock geo-restricted sites.
If you’re getting a proxy error or slow speeds, switching to a different server can help fix the problem.Īs I mentioned earlier, you should first check to make sure your Surfshark-protected connection doesn’t have leaks. And the VPN does so flawlessly, with zero proxy errors.īut in the unlikely event you encounter an issue with Surfshark, be it proxy errors or slow speeds, there a few quick solutions you can try: The VPN hides your real IP address and switches it with a US IP, making it appear as if you’re in the US.Īs a result, you’re able to circumvent Roku’s geo-restrictions and access US channels.

If you’re in a country, say where HBO Max is restricted, you will both be unable to download or access it. The media streamer does so by detecting your IP address to see where you’re streaming from. While that’s frustrating for users, Roku is left with no other option than to block some channels in certain countries. That’s because these streaming platforms and content distributors have licensing agreements that Roku is legally required to comply with. Most of the popular channels like HBO Max, Hulu, and CW are geo-restricted outside the US.
