IP is the acronym of Internet Protocol or, in our language, Internet protocol . It's about a standard which is used for sending and receiving information through a net It brings together switched packets.
The IP does not have the possibility of confirm If a data packet reached its destination. This may allow the package to arrive in duplicate, with damage, in an erroneous order or that simply does not reach its destination.
In case the packets to be transmitted exceed the maximum allowed in the network fragment, the information is subdivided in smaller packages and reunited at the right time.
The IP addresses they refer to the origin and arrival team in a communication through the protocol of Internet . The packet switches (known as switches ) and routers (routers ) use the IP addresses to determine which network section they will use to forward the data.
The IP address is composed of a number that allows to identify hierarchically and logically the interface of a computer or another machine that is connected to a network and that uses the Internet protocol. Internet users, for example, use an IP address that usually changes at the time of each connection. This mode of assignment is known as dynamic IP address .
Reducing what is the number of IPs that have been assigned and are inactive or reducing the operating costs of those responsible for exercising Internet service providers are basically the two advantages that come with the use of the aforementioned dynamic IPs, which They are the ones currently offered by the vast majority of operators.
In addition to all of the above, we have to make it clear that the aforementioned IPs can be assigned by the server in three clearly defined ways, the first one being the one known by the name of the manual. This means that whoever creates it is responsible for managing the network and does it manually.
Secondly, the second form of assignment is the automatic call, which is carried out in this way that gives it a name and taking as a fundamental basis a range that has already been preset by said administrator.
In the third and last place we have to state that there is the dynamic way. This type of assignment has a clear difference with respect to the two previous ones and it is the only one that allows to carry out what it is to reuse IP addresses, that is, to proceed with its reuse. A range of IP addresses established by the administrator and the TCP / IP communication software that each computer has, and that is put into operation when the corresponding network interface card is connected, are the essential elements for this form of assignment to occur .
Internet sites that, for obvious reasons, must be permanently connected, use a static or fixed IP address . This means that the address does not change with the passing of the hours or days.
