How do DC’s share information with each other?

When DC’s enroll into an existing domain, they’re able to find each other and share information. You can also have multiple forests (groups of domains) linked together. You can do this by attaching them to the same “site” (using a directory manager like IDM) or by establishing trusts between the separately configured domains.

Is there a way to share a DNS address between two domains?

There will be no trust established between them unless you manually establish one. The DHCP issue is a valid point, and your potential fix is correct – You can hand out the DNS address of one domain via DHCP, and use a forwarder to resolve the other domain’s namespace.
