It follows a server-client architecture where the client requests a DHCP Server to get an IP Address. Using the 12-bit netmask encompasses this entire available private address range, so in order to be more conservative about the address space that the company actually needs, they decide to increase the number of bits in the netmask they will use. Two network cards. ICMP is used by such network applications as the ping utility, which can determine the availability of a network host or device. 0/12 private address range.

This article focusses on how to configure networking from command line interface.
For optimal performance, set the private network adapter MTU to 1450 when configuring the NIC at the OS level. Unicast means that the data packets are sent to a single target host. UDP is commonly used in such applications as audio and video streaming, where it is considerably faster than TCP due to the lack of error correction and flow control, and where the loss of a few packets is not generally catastrophic. I have to provide the value in the Subnet section in following format:. mtu size MTU size The dhcp Method This method may be used to obtain an address via DHCP with any of the tools: dhclient, pump, udhcpc, dhcpcd. For every additional bit set to 1 in the mask, another bit becomes available in the subnet number to index additional subnets. If you&39;re configuring it manually then something like this will set the default gateway (network, broadcast and gateway are optional): auto eth0 iface eth0 inet static address 192.
