主机名与IP-地址 [英] Hostname vs. IP - address

问题描述

我目前正在将openssl实现到我的应用程序中.当我必须设置BIO的主机名，IP-地址和端口时，出现了我的问题.我一直都知道ip和主机名是同一回事.有人可以解释一下两者之间的区别.

I am currently implementing openssl into my application. My problem arose when I had to set the hostname, IP - address, and port of the BIO. I have always known ip and hostname to be the same thing. Could someone please explain the difference.

推荐答案

主机名是计算机名称和域名(例如machinename.domain.com)的组合.主机名的目的是可读性-它比IP地址更容易记住.所有主机名都解析为IP地址，因此在许多情况下，它们像可互换一样被谈论.

A host name is a combination of the name of your machine and a domain name (e.g. machinename.domain.com). The purpose of a host name is readability - it's much easier to remember than an IP address. All hostnames resolve to IP addresses, so in many instances they are talked about like they are interchangeable.
