Advanced TCP/IP Data Logger inputs TCP/IP, UDP, or HTTP data directly into a file, Excel, MS Access, or any Windows application. This guide is updated periodically with information available at the time of publication. For hosts and ports specific to enterprise networks, learn about using Apple products on enterprise networks. This is a quick-reference guide showing common examples, not a comprehensive list of ports.
