公用IPv4地址的总数是多少? [英] What is the total amount of public IPv4 addresses?

问题描述

是的，我需要知道公共IPv4空间中可能的IP总数.

Yes, I am needing to know what the total number possible IPs in the public IPv4 space.

我不确定在哪里可以得到所有IP地址范围的完整列表，因此有人可以将我指向一个资源来自己计算还是为我计算IP总数?

I'm not sure where to even get a neat list of all the IP address ranges, so could someone point me to a resource to calculate this myself or calculate the total number of IPs for me?

此外，通过公共IP，我的意思是不计算保留的或私有范围的IP地址..仅那些可以通过Internet访问的IP地址.

Also, by Public IPs I mean not counting reserved or private-range IP addresses.. Only the ones that can be access through the internet.

推荐答案

根据保留的IP地址有588,514,304个保留地址，并且由于总共有4,294,967,296(2 ^ 32)个IPv4地址，因此有 3,706,452,992 个公共地址.

According to Reserved IP addresses there are 588,514,304 reserved addresses and since there are 4,294,967,296 (2^32) IPv4 addressess in total, there are 3,706,452,992 public addresses.
