What is one similarity between global and unique local IPv6 addresses?

Both global unicast and unique local IPv6 addresses use the same subnetting methodology, which involves dividing the 64-bit interface identifier portion of the address. The prefix length (e.g., /64) determines the network portion, and the remaining bits are for host identification. This method is consistent across various IPv6 address types. Incorrect options: Both are multicast address types: This is incorrect. Both global unicast and unique local addresses are unicast addresses, meaning they identify a single interface. Multicast addresses are a distinct type used for one-to-many communication. Both are globally routable: This is incorrect. Global unicast addresses are globally routable, but unique local addresses are not. Unique local addresses are intended for private networks and are not routed on the public internet. Both are assigned by the same organization: This is incorrect. Global unicast addresses are typically assigned by Regional Internet Registries (RIRs) or Internet Service Providers (ISPs). Unique local addresses are self-assigned by network administrators and follow a specific format that includes a randomly generated 40-bit global ID.
