The difference between domain name and ip includes:
- conceptual difference;
- difference in effect;
- The difference in the way of identification;
- The difference in the mapping relationship. The conceptual difference can be simply summed up in one sentence, that is, "the domain name is the name of a computer or a computer group, and ip is the ID number of each computer".
1. Conceptual difference
The English name of a domain name is "Domain Name", also known as a network domain, which is the name of a certain computer or computer group on the Internet composed of a string of names separated by dots. And ip is the abbreviation of "Internet Protocol", which refers to the Internet protocol address, which is the logical address used to uniquely identify the computer on the Internet.
2. The difference in function
A domain name is used to identify the electronic location of a computer during data transmission, and sometimes also refers to a geographical location, that is, a local area with administrative autonomy. At present, domain names have become one of the necessary products for the protection of Internet brands and online trademarks.
IP is a unified address format provided by the IP protocol. It assigns a logical address to each network and each host on the Internet to shield the difference in physical addresses.
3. Differences in identification methods
The domain name is used to identify the host in the computer network in a characterized form. For example, "www.baidu.com", which is commonly used when surfing the Internet, belongs to the concept of domain name, and the domain name adopts a hierarchical management method.
The ip address uses digital form to identify the host in the computer network, such as the common 10.254.1.1, 172.16.1.10, 192.168.1.254, etc., all belong to the concept of ip address. There are currently two versions of IP addresses, one is the IPv4 version and the other is the IPv6 version.
4. The difference between the mapping relationship
A domain name corresponds to an ip address or several ip addresses, such as Baidu's ip (119.75.218.70) (119.75.217.109); and the ip address on the Internet is unique, and an ip address corresponds to a computer. But there can be many services on one computer, that is, one IP address corresponds to many domain names .
