So my IPS could not simply assign me a new IP Adddress. I suppose they weren't smart enough! But… in Network Preferences I selected Built-in Ethernet and Manually using DHCP Server. Where my IP Address was grabbed from the server I entered the same 8 numbers and off the top of my head entered the last 3. Ta-da… works great. Haven't had a hit in two hours. So long LimeWire.
