The DNS name is returned in various RPC replies.  As well
as in the CLDAP Netlogon reply:

$ net ads lookup

Client Site Name :              Default-First-Site-Name

You can also infer this information from the defaultNamingContext
attribute in the rootDSE of a domain controller:

$ ldapsearch -x -H ldap://central.plainjoe.org/ -b "" -s base\
  -LLL "(objectc;ass=*)" defaultNamingContext

defaultNamingContext: DC=central,DC=plainjoe,DC=org

Hope this helps.

cheers, jerry
