Using TCP/IP
Now that we’ve covered the protocol stack, let’s concentrate on how TCP/IP works with WS03 and how IP addressing works with your IIS sites.
| Tip | If you’re looking for some IP addresses to use for your own internal network, you can use three blocks that are not in use on the Internet: |
| Note | 192.168.0.0 – 192.168.255.255 172.16.0.0 – 172.31.255.255 10.0.0.0 – 10.255.255.255 |
IPv4 is installed by default in WS03, so all you need to do is configure the connection. By default, WS03 uses DHCP to configure network connections. DHCP is an automatic method of configuring IP addresses, and all the settings are made on the DHCP server, rather than at each individual machine. In this book, we’ll use manually configured IP addresses.
Choosing an IP Address
When choosing an IP address, you need to be aware that you cannot use two addresses in each subnet: The first IP address in a subnet is reserved for the network ID. The last IP address in each subnet is reserved for the broadcast address, which machines use when they want to talk to every machine. Both of these addresses are reserved and unusable. Here is an example of the network ID and broadcast address for two subnets:
| Subnet | Network ID | Broadcast Address |
|---|---|---|
| 192.168.0.0 /24 | 192.168.0.0 | 192.168.0.255 |
| 10.0.0.0 /8 | 10.0.0.0 | 10.255.255.255 |
