Figure 6.28 Query for an Internal Name in the Domain Reskit.com

The query proceeds as follows:
  1. The computer submits a query to its local DNS server, server.first.reskit.com.

  2. If the local server is not authoritative for host.second.reskit.com, the local DNS server queries a root server.

  3. The root server returns a reference to the authoritative server, server.second.reskit.com.

  4. The local server, server first.reskit.com, queries server.second.reskit.com.

  5. Server.second.reskit.com resolves the query and returns the response to the local server.

  6. Server.first.reskit.com passes the response to the client.

  2. If the local server is not authoritative for host.second.acquired01-int.com, the local DNS server forwards the query to the DNS server that is authoritative for the acquired01-int.com zone.
  3. The DNS server that is authoritative for the acquired01-int.com zone finds a delegation to the server server.second.acquired01-int.com and queries that server.
  4. Server.second.acquired01-int.com resolves the query and returns the name to the DNS server authoritative for the acquired01-int.com zone.
