I have power distribution unit with an ethernet interface, that allegedly has been configured to have an IP address of 188.8.131.52 (the network it was on was not on the public internet). That old network is no more, but I have a switch and a laptop running windows 7. I am trying to reach the configuration page of this PDU so that I can change some settings (like its IP address). So far I have been vexed in my attempts to do so, and I blame my rusty skills with IP networking.
For starters, I disconnected my laptop from the internet, and plug my PDU and laptop into my switch. I hardcoded the laptop's IP to 184.108.40.206, with a subnet mask of 255.255.255.0. No joy, I can't ping 220.127.116.11.
So I think the problem is either that the PDU is actually set to a different IP address, or I simply fail to understand how to do IPv4 networking. If it's the former, how do I figure out what the PDU thinks its IP address is? If it's the latter, what am I missing?
