Why Do IP Addresses Change?
IP addresses are the numbers assigned to a particular device in a computer network. You can think of it as your house address where you send your mail so that it will not get lost. The IP addresses assigned to your computer make it easier for data to be sent to you without getting lost in the big world of computer networks.
Some IP addresses change each time you use the device to connect to the network. This is mainly because you have a DCHP network configured in your computer. DHCP is referred to Dynamic Host Configuration Protocol wherein a central server is assigned to give out IP addresses to each device that connects to the network. IP addresses in a DCHP network are dynamic IP addresses meaning you get a new one every time you log in and log off the network.
Home DSL connections usually get a dynamic IP address. Getting a static IP address or the one that does not change will cost you because you will have to pay for its use. IP addresses are often reused by DSL companies to accommodate the number of subscribers that they have. Dynamic addressing is also done to free them of the administrative burden of assigning IP addresses each time a device logs into the network. It helps in sharing the available resources by sharing it with the maximum number of subscribers.
IP addresses change to help in preventing hackers and other people from entering and gaining access to your computer. It makes hacking and remotely accessing your computer harder because you do not have one IP address all the time. Since IP addresses change, people who have evil intentions will have a hard time accessing the files in your computer. Changing IP addresses are there to help us make our network experience an easy one. It also keeps our data safe from hackers.
