In general, I want that when a new poppy address appears or a substitution (interception) occurs, the admin's scoreboard lights up with the inscription "Akhtung!!! They are trying to hack us!!!" And now any fool can come with a pocket router (from a matchbox) and capture the organization's network (or just disrupt work) - by substituting IP addresses.

Answer 6

The right question is 90% of the answer.
1. MAC addresses in current pieces of iron are easily changed.
2. In such a situation, a switch that can authorize a port connection through Radius saves. In this case, even encryption can be enabled. Even for WiFi, such authorization is the best solution.
3. Intel security (formerly McAfee) has Rogue System Detection.
