We have four domain controllers their IPs are completely different than this one.

When I ping domain.com I am getting reply with 10.10.10.10 not my domain controllers IP

tracert 10.10.10.10

Leave it alone.  It's there to tell clients where the domain is at IP-level.
The domain isn't at that ip

while tracert this IP it says unreachable, but if i remove this from DNS or core switch it disconnect the internet. yes only one NIC per domain.
