What happens? Hacked.Yes, but if the DHCP database has a mistake it's pretty much the same situation since it could be numbered with a public address.
Um. No. You'd have to make multiple mistakes cross-contaminating your public and private ethernet segments yet somehow without completely breaking your network rendering it inoperable.
