NAT IPv6
IPv6, with its 128-bit addresses offering 340 undecillion possibilities, was designed to eliminate the need for IPv4 NAT by avoiding public-to-private address translation. It includes unique local addresses (ULAs) for site-local communication, not for expanding address space or enhancing security.
-
These hosts can share an IPv4 address from the pool because PAT is enabled with the keyword overload.
