Potentially Rogue Device

Hi Everyone,

Yesterday at my company, we had an issue where people were not able to connect to the internet. Upon further investigation, it was revealed that we ran out of out of DHCP leases and that a TV with Chromecast was taking up several IP addresses. It was also imitating the names of other devices that were previously connected to the network.

- Has anyone seen anything like this before?

- What are some of the possible scenarios that could explain this?

- What can be done to prevent such a situation in future?
