Many people make the mistake of confusing the IP address with the MAC address, when these two are very different. The MAC address is a unique identifier assigned by the manufacturer to a 48 bit piece represented by hexadecimal digits to identify the network card and other devices, where it does not depend on the connection protocol using the network. For users it is easier to remember a domain name than the numbers of the IP address, then the DNS domain servers, “translate” the domain name into an IP address.
This address can be static or dynamic. The first one helps us to establish permanent connection so that they can be located in the network, that is, a web page needs a fixed static address so that all its visitors can locate it easily without having to abandon it simply.
because find it If the IP of a website changed at every moment it would be almost impossible to locate it and to do it would take a long time to do so. While the dynamic direction unlike the first the identification changes periodically, thus making the tracking of it a bit more difficult, usually this type of IP is used by users since it can change when restarting the Reuter.
There are two types of IP addresses, which are Public IPs and Private IPs, where each of them has a totally different purpose.
Public IP: is that address that is generated automatically and is visible from the Internet, it never changes, thus achieving that your device or computer is always identified.
Private IP: this type of address is assigned manually and belongs to a private network. One of its many functions is to identify a machine with this type of address, although it can be repeated in other private systems.
