⚠️ Risk Warning:
Please select this method cautiously as it's easier to cheat and more difficult to be detected (e.g., attendance group members may cheat through virtual IP software).
I. Overview
Additional notes:
- 1.What is a public network IP?
Also known as WAN IP, it refers to the non-reserved address on the Internet which is connected with the public network (WAN and LAN are 2 types of Internet access. Computers on WAN and other computers on the Internet can freely access to each other).
- ◦IP address:
- ▪It refers to Internet Protocol addresses. The IP address is a unified address format provided by the IP, which assigns a logical address to every network and host on the Internet to avoid differences in physical addresses.
- ◦Public network IP field range:
- ▪Class A: 1.0.0.0 to 127.255.255.255. Mainly allocated to large networks with many hosts but a small number of LAN networks.
- ▪Class B: 128.0.0.0 to 191.255.255.255. Generally used in large international companies and government agencies.
- ▪Class C: 192.0.0.0 to 223.255.255.255. Generally used in small companies, campus networks and research institutions.
- ▪Class D: 224.0.0.0 to 239.255.255.255. Used for a special purpose. It's also called a broadcast address.
- ▪Class E: 240.0.0.0 to 255.255.255.255. Temporary unallocated.
- 2.Under what circumstances can public network IP attendance be configured?
When the office network has a unified exit IP, the attendance groups of this office area can be configured with public network IP attendance.
- ◦Advantages: Compared with Wi-Fi MAC addresses, the public IP address is relatively stable and without frequent change.
- ◦Disadvantages: Attendance group members can counterfeit the IP address through virtual IP software. It's easier to cheat and more difficult to be detected.
