单词 private IP address
释义

private IP address

An Internet Protocol (IP) address set aside for use within a LAN, intranet, or other

private network and not for use in a public network such as the Internet. Also known as Network 10

addresses, in reference to the first field in the first address range, private IP addresses fall into the following ranges:

• 10.0.0.0 to 10.255.255.255

• 172.16.0.0 to 172.31.255.255

• 192.168.0.0 to 192.168.255.255

Routers are not supposed to forward any packets to the public Internet from IP addresses in those private ranges. When a LAN-attached computer requires access to the public Internet, it is necessary that the private IP address be translated into a public IP address.The process takes place in a router that interfaces to both domains and runs the Network Address Translation (NAT) protocol, as defined in RFC 3022. See also Internet, IP, IP address, LAN, NAT, network, packet, protocol, and router.
