What is the relationship between domain names and IP addresses on the internet

The relationship between domain names and IP addresses on the Internet is that one IP address corresponds to multiple domain names, and the domain name is the name of a certain computer or computer group on the Internet consisting of a string of names separated by dots. An electronic location used to identify a computer during data transfer.

What is the relationship between domain names and IP addresses on the Internet?

In the Internet, the relationship between the domain name of the host and the IP address of the host is that one IP address corresponds to multiple domain names.

A domain name is the name of a computer or computer group on the Internet consisting of a string of names separated by dots. It is used to identify the electronic location (sometimes also the geographical location) of the computer during data transmission.

DNS is a core service of the Internet. As a distributed database that can map domain names and IP addresses to each other, it allows people to access the Internet more conveniently without having to remember that they can be directly accessed by machines. Read the IP address string.

Extended information

When data is transmitted in the IP Internet, it will be encapsulated into messages or packets. The uniqueness of the IP protocol is that in a message-switched network, before a host transmits data, it does not need to pre-establish a specific self-"path" with a destination host that has not communicated with it before.

The Internet Protocol provides an "unreliable" packet delivery mechanism (also known as "best effort"); that is, it does not guarantee that data will be delivered accurately.

Data packets may arrive damaged, out of order (compared to other packets transmitted together), redundant, or lost altogether. If the application needs to ensure reliability, other methods are generally needed, such as using upper-layer protocol control of IP.
