Configuring TCP/IP networking

закрыть рекламу


A network connection is created automatically if a computer has a network adapter and is connected to a network. If a computer has multiple network adapters and is connected to a network, one network connection is created for each adapter. If no network connection is available, you should connect the computer to the network or create a different type of connection.

Computers use IP addresses to communicate over TCP/IP. Windows Server 2012 R2 provides the following ways to configure IP addresses:

? Manually IP addresses that are assigned manually are called static IP addresses. Static IP addresses are fixed and don’t change unless you change them. You usually assign static IP addresses to Windows servers, and when you do this, you need to configure additional information to help the server navigate the network.

? Dynamically A DHCP server (if one is installed on the network) assigns dynamic IP addresses at startup, and the addresses might change over time. Dynamic IP addressing is the default configuration.

? Alternate addresses (IPv4 only) When a computer is configured to use DHCPv4 and no DHCPv4 server is available, Windows Server 2012 R2 assigns an alternate private IP address automatically. By default, the alternate IPv4 address is in the range 169.254.0.1 to 169.254.255.254 with a subnet mask of 255.255.0.0. You can also specify a user-configured alternate IPv4 address, which is particularly useful for laptop users.
