In my settings, windows PC points to company DNS server, and company DNS 
server forwards AD query to AD DC.
When I move PC around(to different vlans with different IP address), the 
A record in AD DC gets updated within half a hour or so.
When I join a PC to my domain, the A record gets added in AD DC immediately.
I don't know how windows PC update the A record in DC: does it go 
through company DNS or go to AD DC directly? (I am using Samba 4.8.12)
