Configuring a DNS Server for 9564488983.tmobile.local

This page demonstrates the basic steps to configure an internal DNS server for the intranet domain 9564488983.tmobile.local. The example assumes a Windows Server–based DNS role, but the concepts apply to other DNS platforms as well.

1. Prepare the DNS Server

1. Install DNS Role: On the designated server, add the DNS Server role using Server Manager or PowerShell.
2. Assign Static IP: Configure a static IP address on the server (e.g. 10.0.0.10) and set its own IP as the primary DNS.
3. Verify Hostname: Ensure the server hostname is appropriate for the environment (e.g. dns01.9564488983.tmobile.local).

2. Create the Forward Lookup Zone

1. Open DNS Manager: Launch dnsmgmt.msc on the DNS server.
2. Add New Zone: Right-click Forward Lookup Zones → New Zone….
3. Zone Type: Select Primary zone and store it in Active Directory if available.
4. Zone Name: Enter 9564488983.tmobile.local as the zone name.
5. Dynamic Updates: Choose the appropriate dynamic update setting (e.g. secure only in a domain environment).

3. Add Host (A) Records

1. Open the Zone: Expand Forward Lookup Zones and select 9564488983.tmobile.local.
2. Create A Records: Right-click in the zone → New Host (A or AAAA)….
3. Example Records:
   • dns01 → 10.0.0.10 (DNS server)
   • web01 → 10.0.0.20 (internal web server)
   • app01 → 10.0.0.30 (application server)
4. Create an NS Record: Ensure the zone has a Name Server (NS) record pointing to dns01.9564488983.tmobile.local.

4. Configure Reverse Lookup Zone (Optional but Recommended)

1. New Zone: Under Reverse Lookup Zones, create a new primary zone.
2. Network ID: Enter the network ID (e.g. 10.0.0).
3. PTR Records: Allow automatic creation of PTR records when you add A records, or create them manually.

5. Point Clients to the DNS Server

1. Client DNS Settings: On intranet clients, set the DNS server to 10.0.0.10 (or your DNS IP).
2. Test Name Resolution: Use ping web01.9564488983.tmobile.local or nslookup to verify resolution.
3. Document Configuration: Record IPs, hostnames, and zone settings for future audits and training.

Note: In a real military college environment, all changes should follow established change-control procedures and be documented in accordance with institutional and security policies.
