Correct IP address format, such as [192.168.0.1], Class D address is used for multicast, the first byte of Class D IP address starts with "1110", which is a specially reserved address. Class E IP addresses, starting with "1111", are reserved for future use.
Correct IP address format: 192.168.0.1;
1. IP addresses are used to give computers on the Internet a number. What we see every day is that every connected PC needs an IP address in order to communicate normally. We can compare "personal computer" to "a telephone", then the "IP address" is equivalent to the "telephone number", and the router in the Internet is equivalent to the "program-controlled switch" of the telecommunications bureau.
2. The Internet Committee has defined 5 IP address types to suit networks of different capacities, namely Class A ~ Class E. IP addresses are usually expressed in the form of (a.b.c.d) using "dotted decimal", where a, b, c, and d are all decimal integers between 0 and 255. It's actually 32-bit binary (01100100.00000100.00000101.00000110).
3. Class D addresses are used for multicast. The first byte of the Class D IP address starts with "1110", which is a specially reserved address. It does not point to a specific network. Currently, this type of address is used in multicast. Multicast addresses are used to address a group of computers at a time, with the address range 224.0.0.1-239.255.255.254.
4. Class E IP addresses, starting with "1111", are reserved for future use. Class E addresses are reserved for experimentation and development only.
