Strange IP in my router ? What is it ?

[orion23]

So this is listed as an available ip for a dhcp reservation:

Unknown
108.121.83.xx

It traces back to sprint pcs ?

Very strange. It wouldn't even make sense to have a DHCP reservation in the router for a public IP address. The router only controls DHCP for the LAN (local area network) behind it.

I would do a firmware upgrade, then factory-reset, then configure again from scratch as if it was brand-new out of the box.

I would do a factory reset, *then* a firmware upgrade, then another factory reset, then reconfigure. If it's malware (I doubt it, probably some wonky bug or something left over from the manufacturers internal testing), upgrading firmware on a malware infected router could flat out brick it. Better safe than sorry.

What is the make and model of router? The Linksys E1200 suffers from The Moon worm and Netgear routers need a firmware update. http://www.bbc.com/news/technology-34491583

I almost fell out of my chair when I read that. Do you have any smart appliances or phones accessing it? Take an inventory of the devices attached vs what you have and go from there.
