This read-only object shows the IP address the peer terminal has assigned to its Slip-Out interface, the counterpart output side of its serial-over-IP passthrough. Reading it lets a manager verify the far-end Slip-Out addressing is consistent with what the local Slip-In destination expects. As an example, if wvSlipOutDestIPAddress on the local unit doesn't match what wvPeerSlipOutIPAddress reports, that mismatch would explain why serial data forwarded through the Slip path isn't arriving.
