Internet is a public lan

All IPv4 IP addresses can be divided into two major groups: global, or public, or external - this group can also be called 'WAN addresses' — those that are used in the internet, and private, or local, or internal addresses — those that are used in the local network (LAN).

互联网是一个全球性的公共网络，连接了世界各地的计算机和网络，让人们能够共享信息和资源。这个说法是正确的。
