Some of you are making this harder than it needs to be.....
If you move, you must notify the ISP of your new address within 60 days (whether you move to another Indiana address or to Egypt.) If that new address is outside of Indiana, your LTCH is no longer valid. If you subsequently move back into Indiana, and notify the ISP yet again of your new address, the LTCH address will be changed to your current address and it once again is active. You cannot use your Indiana LTCH in another state if it is not currently valid in Indiana.
