What is my IP?

IP is the Abbreviation of Internet Protocol (Internet Protocol), which is the network layer protocol in the TCP / IP system. The purpose of the IP design is to improve the scalability of the network: one is to solve the problem of the Internet and perform the interconnection and intercommunication of large-scale heterogeneous networks; The other is to divide the coupling ratio between the upper level network application and lower-level network technology to facilitate the two independent development. According to the principle of end-to-end design, IP only provides a data packet transmission service without connection, not reliable and with the best effort for host.

The IP address (Internet Protocol Address) refers to the Internet Protocol address, which is also translated as an Internet Protocol address. IP address is a unified address format provided by the IP protocol. Assigns a logical address to each network and each host on the Internet to protect the differences in the physical addresses.

No operation is allowed. When you can connect to the Internet, you just need to open this website and you can know your IP address and your Internet Service Provider (ISP) .

Configure computers, such as maintenance of the network. When configuring servers (such as FTP and HTTP servers), you need to know the IP address.

The public IP is the only one in the world, through which you can directly access the Internet (you can directly access the Internet). The public IP address is a number that allows two computers to recognize each other. When connecting to the Internet, an ISP (Internet service provider) usually assign an address to the user's computer. Private IPs are generally used for the IP used in our company or home to build a LAN. If a computer in a company or in a home you want to access the Internet, you must use "NAT Technology" at the boundaries of the company to convert the IP of the private network into the IP of the public network to be able to access the Internet normally.

Version 4 of the Internet Protocol is the fourth version in the development of the Internet Protocol, and also the first version of the protocol widely implemented and used. The top version is IPv6, and all IPv6 implementation phases lasted until 2011, when IA's IPv4 addresses were completely exhausted. Usually, your public IP address is an IPv4 address. IPv4 consists of decimal numbers separated by points, such as: 8.8.8.8

The Internet Protocol Version 6 (Internet Protocol version 6, abbreviated: IPv6) is the latest version of the Internet Protocol. It replaces IPv4 mainly to solve the exhaustion problem of the IPv4 address, and also has many improvements to IPv4 in other aspects. IPv6 consists of hexadecimal numbers separated by two points, such as: 2020:db8:0:1234:0:567:8:2. IPv6 Adoption Statistics: https://www.google.com/intl/es/ipv6/statistics.html

Dynamic IP refers to the IP address allocation method when necessary. The dynamic call means that each time it is connected, the ISP will randomly assign an IP address and safety is also relatively high. Generally, the IP address will change after your router restarts. A static IP is a fixed IP. If your ISP gives you a fixed IP, it will also indicate the corresponding mask and gateway. Then you can configure this IP in the local connection to connect to the Internet directly without obtaining an IP address.

The IP address is a unified address format provided by the IP protocol. Assign a logical address to each network and each host on the Internet to protect the differences in the physical addresses. The MAC address is also called a physical direction and hardware direction, and is used to define the location of the network computers. The physical address of the network card is usually recorded on the network card by the network card manufacturer and is unique worldwide.
