I understand what and how to set "Connection-specific DNS suffix", and I mostly understand the purpose. My question is just about why only certain network connection/adapter has it by default (even when UI shows it empty). For example, for my case the wired/LAN connection has it like (
Ethernet adapter MAIN: Connection-specific DNS Suffix . : abc.corp.com Description . . . . . . . . . . . : Intel(R) Ethernet Connection
The UI (Advanced TCP/IP -> DNS Tab) shows it empty. If I set it to something,
IPCONFIG will show that, but if I keep it empty, 'abc.corp.com' will be shown by command.
When I connect to wireless, the "Connection-specific DNS suffix" remain empty by the output of
IPCONFIG. (Actually, it doesn't matter if connected to wired/wireless).
So, the question is just:
- Why wired connection (or any) has it by default. Is DHCP or DC sending it? Is it part of some TCP/IP protocol? Or is it coming via some group-policy (failed to find)?
/RELEASE the IPCONFIG, but it doesn't effect.
