What is the translation of the network address?
Metal address translation (NAT) is a dynamic method of consolidation used systems to minimize Internet connection needs. Specifically, the translation of the network address describes the rewriting of the address of the Internet protocol (IP) of data packets so that more transmissions require only one IP address. The rewriting takes place when data goes through a network or network firewall. This is done on a private network. In addition to Firewall, the company also uses routers or even computers to perform network address translation functions. Static NAT translates one unregistered IP address to another, registered. Dynamic NAT translates one unregistered IP address to the other selected from the group of registered addresses. Overload is a form of dynamic NAT, which translates a number of unregistered addresses into one registered. Overlapping translates multiple addresses from one net to another. Each method is used according to the specific needs of the company.
One of the main reasons for using a network address translation is to maintain IP addresses. Many experts in the field believe that an explosion of IP addresses will lead to a global deficiency created by eliminating all available permutations in the 32 -bit IPv4 standard, which dominates today on the Internet. One of the methods of solving this problem was to create IPv6, which includes 128 bits and extremely more options for IP addresses. However, creating IPv6 is not really solving a lack of deficiency. The translation of the network address is not created by new IP addresses unless they are needed.
One disadvantage of the translation of the network address is that it does not allow the actual connection from rug to completion. In other words, if the connection comes from the outside of the network, then the network translation protocols cannot ensure that the data will remain intact all the time. The fact that the original IP was not connected to the net that started is a mitigating factor.
On the other hand, this mitigating factor can beKé advantage. If the translation of the network address does not allow data transfer from the wire from the source outside the network, then it naturally serves as a barrier of data streams with a great intention. This kind of functionality can naturally serve as a security service that maintains viruses, worms and other danger.
