IP Addressing
Strong> p>
akhir2 nich an organization that studies a lot about networking, because networking is the need in the world of work. Moreover, in mengkomonikasikan data to ensure the delivery of packet data and arrive at destination in need of a lawyer alamatan computer or IP address. Ip address extremely important role in the network because the IP address of a data gateway to our computers can share resources with other computers or the Internet. Brikut will describe about the IP address and IP address in network settings p>
Introduction IP address strong> p>
IP strong> or frequently called Internet Protocol is dengna an identity for each computer in the network, or network. This is an ip address on a computer that is very unique, this is caused by any existing computer in the network must have a different IP address, so that later in the data transmission will not occur span> IP conflig, strong> p>
line-height: following is an example of IP addresses p>

IP address in writing in the format of 32 bits or 4 bytes but in order to make easier to read then in use in separating the IP address octet form. Actually ip in writing using binary numbers but this is very difficult for network administrators to determine the IP addresses of each kompuer, so the ip address in the conversion to decimal is easy to specify, p>

11 million. 10.101 million. 00,000,011. 00000001 p>
line-height: fourth value has a maximum value of 255 and has a minimum value 0 ip address so if contains the digits 1 will all be numbered as the following 255 255 255 255 and if the contents of the numbers 0 all this will be as follows in 0.0.0.0 so vane many hosts of a network that can work as much as 4,294,967,296 address after the cut with the number of ip addresses to broadcast and multicast. p>
subnetting strong> span> p>
subnetting is a division of the host so that the network does not occur in a host of waste, for example, it is only necessary if the network host as many as eight fruit then we are very wasteful if you use a class C then the computer that is available in the network 255 units. This can lead to extravagance in the network p>
Example: will the use of a class C network address of 192.168.0.1 (the address can specify the ip address 254). The division is done by using a network subnetwork mask, each bit in the network mask in use for the network bits set to 1, and for the host bits set to 0 so that the network mask in use for a class C 255.255.255.0 as bits will be made in be as follows p>
span> 111111111.1111111111.11111111.0 strong> span> p>
subnetwork created by borrowing one or more host bits to be used to divide the network bitsehingga all network addresses into two subnetworks, one host bits borrowed to be used as network bits, so the network will be as follows masknya p>
111111111.1111111111.11111111.10000000 p>
255. 255. 255. 128 p>
from the example above can be in the know that a network address can only be in for a second rank span> n. Strong> size of the smallest subnetwork consists of four IP addresses, consist of two four IP addresses, consisting of two IP addresses that can be used for host addresses, a network address and a boardcast address. Span> p>
To find out more on the desired hosts can also use the format of the slash (/), such as network address with netmask 192.168.100.0 255.255.255.0 can be written into 192.168.100.0/24, numbers / 24 obtained from the number of network bits in the netmask, consider the following example: p>
255. 255. 255. 0 p>
11111111.11111111.11111111.00000000 p>
number of network bits in the example above is 24 because it looks using a / 24. p>

subnet technique is a way that is used to allocate IP addresses on a network (LAN or WAN). Subnet technique becomes important if we have a limited allocation of IP such as IP there are only 200 will be distributed to multiple LANs. P>

To give an illustration, suppose that we have the allocation of IP addresses from 192.168.1.0 s / d to 254 host 192.168.1.255, then the parameters used for allocation are: p>
