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

Also check the event logs.

run ipconfig /registerdns on all Domain Controllers
dcdiag /fix on one domain controller
right click the forward lookup zone and properties... click name servers tab.  make sure only the 4 domain controllers are there.

what is the DNS for the actual domain controllers on the NICs? only one nic per Domain Controller correct?

Delete the 10.10.10.10 same as parent folder record.. that should not be there.

each domain controllers own NIC should point to another DC and 127.0.0.1

Leave it alone.  It's there to tell clients where the domain is at IP-level.
