IMO it's much easier to disable one rogue than to disable IPv6 on the
whole network. That is if you can find it, but with some proper
tcpdumping and/or CLI commands (depending on the switches that you have)
it should be relatively easy.

Even better, the IPv6 gateway you got assigned is based on the MAC address. That means you can also find what brand of device is advertising.

You can most likely find which IPv4 address the MAC corresponds too as well. Was that so hard?

Not to mention that, as pointed by others, this provides a wonderful
opportunity to look into this new (*grin*) protocol.

Indeed!
