The problem of obtaining the number of users with different IP addresses is to obtain the number of all different ip addresses in a table. The table name onlineip field name cannot obtain different ip addresses after the

I used to set multiple ip addresses of different network segments on the local machine, and then switch the route so that different network segments can go out through different gateways, you can access multiple networks at the same time. However, I often find that some problems may occur, so I decided to use the most

number of valid external IP addresses. If all the dynamically allocated external IP addresses in the NAT pool are occupied, subsequent NAT translation requests will fail. Address overloading can be used to identify different connections by port numbers.For example, DCR-2501/DCR-1700/DCR-3600 router configuration:

encourages IT vendors to make efforts to better manage IP addresses. VoIP converts a phone number into an IP device, potentially doubling the number of IP addresses. The focus of Network Security began to shift from unknown devices to network access and potential virus infections, which also forced companies to better manage network access. IT provides end users

The architecture automatically resolves the DNS servers of different IP addresses, such as Linux Enterprise applications and Linux server applications, based on the users of China Telecom and China Netcom. The following is a detailed description. This document is based on FreeBSD and BIND platforms. Win users should be avoided. If there is no FreeBSD basic, do not. Linux or other Unix users can serve as ref
