域名和ip的区别包括：
- 概念上的区别；
- 作用的区别；
- 标识方式的区别；
- 映射关系的区别。概念上的区别可简单概括为一句话，即“域名是一个计算机或者一个计算机组的名称，而ip是每一台计算机的身份证号”。
1.概念上的区别
域名英文名称为“Domain Name”，又称网域，是由一串用点分隔的名字组成的Internet上某一台计算机或计算机组的名称。而ip是“Internet Protocol”的缩写，指互联网协议地址，是用来唯一标识互联网上计算机的逻辑地址。
2.作用的区别
域名用于在数据传输时标识计算机的电子方位，有时也指地理位置，即指代有行政自主权的一个地方区域。目前域名已经成为互联网的品牌、网上商标保护必备的产品之一。
而ip是IP协议提供的一种统一的地址格式，它为互联网上的每一个网络和每一台主机分配一个逻辑地址，以此来屏蔽物理地址的差异。
3.标识方式的区别
域名用字符化形式来对计算机网络中的主机进行网络标识，例如上网时常用的“www.baidu.com”，就属于域名的概念，域名采用层次化的管理方式。
ip地址用数字化形式来对计算机网络中的主机进行网络标识，如常用见的10.254.1.1、172.16.1.10、192.168.1.254等都属于ip地址的概念。目前有两个版本的IP地址，一个是IPv4版本，一个是IPv6版本。
4.映射关系的区别
一个域名对应一个ip地址或好多个ip地址，比如百度的ip（119.75.218.70）（119.75.217.109）；而因特网上的ip地址是唯一的，一个ip地址对应一个计算机。但一台计算机上面可以有好多个服务，也就是一个ip地址对应了好多个域名。
