I've been pretty happy with unbound for a similar setup.
It can be configured to disable caching so it can do what you are looking for:
You can configure *.go.com as a forward zone.
I would start here: https://calomel.org/unbound_dns.html
forward zone configuration:
name: <domain name>
Name of the forward zone.
forward-host: <domain name>
Name of server to forward to. Is itself resolved before it is
forward-addr: <IP address>
IP address of server to forward to. Can be IP 4 or IP 6. To use
a nondefault port for DNS communication append '@' with the port
forward-first: <yes or no>
If enabled, a query is attempted without the forward clause if
it fails. The data could not be retrieved and would have caused
SERVFAIL because the servers are unreachable, instead it is
tried without this clause. The default is no.
