  • A They are used to access the Internet from the internal network without conversion.
  • B They are used in place of public addresses for Increased security.
  • C They are used with NAT to preserve public IPv4 addresses.
  • D They are used by Internet Service Providers to route over the Internet.
Explanation

RFC 1918 address space consists of private IPv4 ranges intended for internal networks and not for direct routing on the public Internet. In practice, these private addresses are commonly combined with NAT so internal devices can share one or a small number of public IPv4 addresses, which helps conserve public IPv4 address space.
