I am wondering if it is possible to find out where some of our addresses are being used. Every time we use an IP address that is xxx.xxx.xxx.1 or xxx.xxx.xxx.2 of our C-class public subnet data transmisttion is not possible. Other addresses in the C-Class subnet work fine. Pinging the address when our IP address is taken off line, results in no response. Is there anywhere I can go to get this looked into?
