   bankofamerica.com.lan
It can't be used in the wild, compared to bankofamerica.com.security.itdept.xyz in the email, but it opens a way for a directed attacks to be way easier. Especially considering the awful security record of most 'SOHO' routers out there.

Sure, you can respond with evil bit set to zero for IoT devices...




Just to be clear I mean if the browser bar says accounts.google.com, you get the internet "level" validation. Regardless if the IP resolved by malicious dns is 10.0.1.1

This would be an extension of the recent HSTS preload list trend of associating a particular TLD (e.g. .dev) with a particular mechanism, and would not affect other tlds than (say) .lan or ip ranges
