I had a similar discussion with another vendor recently while testing their
mesh wireless systems. This vendor’s units are actually re-writing dhcp
requests that clients make to point DNS to the primary mesh unit. This even
happened when the mesh platform was in pure bridge mode (as opposed to router
mode). The vendor said this was to make sure their app worked reliably. I’d say
this sort of behaviour has quietly become common in the one app to rule it all
world.

Subject: {Disarmed} Re: Asus wifi AP re-writing DNS packets
Hello
An update on this issue:
Going through (long) Asus support channel, they first agreed that this was
intentional to make router.asus.com <http://router.asus.com> work but did take
my request to make that optional. They have issued me a test firmware which so
far seems to be working perfectly with no-rewriting rules. Hoping that it
doesn't bring any side effects and they eventually put it in their public
release after testing.
