Great! It likely did have that IP sometime during its lifetime. I’ve had it reset to an old IP also that I used to use. I’ll usually change the jumpers to DHCP, get it back to something known, then reconfigure static. Last time it happened though I ended up giving it a fixed IP through the router’s MAC address table and left it on DHCP. That was a couple of years ago and I’ve never had it happen again. 🙂
