Before you configure TCP/IP, complete the tasks that are listed in the following table.
| Task | Description | For Instructions | 
|---|---|---|
| 1. Design the network topology. | Determine the physical layout of the network. | Network Topology Overview and IPv4 Autonomous System Topology | 
| 2. Obtain a network number from your ISP or Regional Internet Registry (RIR). | Get a registered network number, which enables systems at your site to communicate externally. | |
| 3. Plan the IPv4 addressing scheme for the network. If applicable, include subnet addressing. | Use the network number as the basis for your addressing plan. | |
| 4. Assemble the network hardware depending on the network topology. Assure that the hardware is functioning properly. | Set up the systems, network media, routers, switches, hubs and bridges that you outlined in the network topology design. | The hardware manuals and Network Topology Overview. | 
| 5. Assign IPv4 addresses and host names to all systems in the network. | Assign the IPv4 addresses during Solaris OS installation or post installation, in the appropriate files. | Designing Your IPv4 Addressing Scheme and How to Change the IPv4 Address and Other Network Configuration Parameters | 
| 6. Run configuration software that is required by network interfaces and routers, if applicable. | Configure routers and multihomed hosts. | Planning for Routers on Your Network and Configuring an IPv4 Router for information on routers. | 
| 7. Determine which name service or directory service your network uses: NIS, LDAP, DNS, or local files. | Configure your selected name service and/or directory service. | System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP). | 
| 8. Select domain names for your network, if applicable. | Choose a domain name for your network and register it with the InterNIC. | System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP) |
