1. IntroductionIP is the most central protocol in the family of TCP/IP protocols. All TCP, UDP, ICMP, and IGMP data are transmitted in an IP datagram format. IP provides unreliable, non-connected datagram delivery services.(1) unreliableIt does not guarantee that IP datagrams will successfully reach their destination.
The pure version of IP data files can be used to optimize the query method, improve the format conversion efficiency, reduce the number of file reads, and quickly query IP addresses online. Greatly reduce the number of file reads, which should be beneficial to protecting the server's hard disk. Add a database browser to view the qq ip data files of the pure versi
