Subnet
One of the most complicated tasks performed by TCP / IP is to determine whether the specified IP address is on the same subnet. Tasks are complex like TCP / IP using IP address and subnet mask.
The IP address should look like 192.168.10.52. The IP address is always stored with numbers from 0 to 255 separated by periods. Part of the IP address is called the network ID and serves as a unique identifier for a specific subnet.
Other IP addresses make the host ID and the specific computer or network device and subnet unique. How do I have to have an IP address part of what I have to do? Use the subnet mask. The subnet mask is very similar to the IP address, but there is a group of 255.255.255.0. Just understand like a binary machine of this computer. Since it means a subnet mask for IP address
Binary.
Switching the calculator on Windows to scientific view, you can convert the numbers from decimal to binary.
Tips
Convert all groups of numbers (octets) to binary code. For example, if the ip address is 192.168.10.41 and the subnet mask is 255.255.255.0, in binary it looks like this:
Address or mask 1st octet 2nd octet 3rd octet 4th octet
192.168.10.41 11000000 10101000 0000101010 00101001
255.255.255.0 11111111 11111111 11111111 00000000
The place where "1" is displayed in the subnet mask corresponds to the IP address part which is the network ID. You see "0" in the subnet mask Everyplace
In the part of the IP address which is the host ID. Here, the network ID is 192.168.10, and the host ID is 41. TCP / IP processes everything with an IP address beginning with 192.168.10 as though it is on the same subnet. IP addresses starting with something other than 192.168.10 will be treated as if they reside on a different subnet.
Basic TCP / IP service
Multiple protocols TCP / IP suite and core protocols, these are usually TCP / IP using any network currently. You can create a network that does not provide basic services to core protocols. Tsutsu
_ Data transmission. User Datagram Protocol (UDP) and Transport Control Protocol (TCP). If you are not paying attention to small packet data required for computer-based UDP, actually receive the data on the remote computer. In the case of TCP using a computer When you reply to a remote computer that can TCP by sending load data, we will accept a request for confirmation at a given window.
_ Name resolution. In Domain DNS, you can use easy-to-remember names like the following: www.microsoft.com Computers can convert these names to numerical IP addresses.
_ Windows Internet Name System (WINS). In previous versions of Windows also use Win IP address to translate computer name. WINDOWS Server 2003 is compatible with WINS.
