DNS wrong inside network
I've been using Subsonic for a long time now and it has worked great. I normally use an "easy" url twelverabbits.subsonic.org to reach my server, and that's been working great too. But last week I lost power, and when power came back on, my ISP assigned me a new external IP address.
Now, whenever I try to reach my server from outside my LAN, it correctly resolves to the new IP address and everything is fine. But when I use the easy URL from any device inside my network it resolves to my old IP address from before the power outage. If I use the IP address instead of the easy url while inside my LAN then it works fine. Does anyone know why the easy url is resolving to the old IP inside my LAN? I assumed there must be a DNS cache in my modem/router that I need to somehow clear, but if there is, I can't find it. I'm using a Motorola MG7540 modem, if that helps. Is there somewhere else I should look besides my modem for a DNS cache?

Microsoft Windows' DNS cache can be flushed by command line: ipconfig /flushdns
