(UNIX and linuxracktables call themselves a "management framework for rack space, IP addresses, servers, switches, routers, etc.". It has a web interface that performs reporting and configuration, and manages name services. Racktables is based on PHP5, Apache and mysql. It can realize accurate network connection management, and has a unified search function and a multi-user access module. However, the documentation is poor, so it takes some time to figure out how it works.)
