However, this dynamism can sometimes make the connection more unstable. This type of dynamic IPs contributes to our privacy since they make it more difficult for websites to track us as they change. They are usually deleted after each session is closed or change automatically at indefinite intervals (when a device disconnects from the network, the IP is released and another interface receives it). Choosing one or the other will depend on our connection and network accessibility needs.ĭynamic IP addresses are mostly assigned by Internet operators to their customers and are used to browse the Internet regularly. Which one is better for me, a dynamic or static IP address?Īn IP address can be dynamic or static depending on who assigns it and for what purpose. Depending on whether it is an IP address for large networks, medium-sized networks, or for home use, the first group of octets, the first two or the first three, respectively, are used to identify the network, while the remaining groups, three, two or one, depending on the case, correspond to the device identifier. The IPv4 address is divided into four groups of numbers or octets of 8 bits each, with digits between 0 and 255. The three leftmost fields of the address contain the site prefix, the next is the subnet ID and the four rightmost fields identify the interface ID. The addresses of this version are composed of 128 bits, which multiplies almost to infinity the number of addresses that can be generated, about 340 sextillions, compared to the 43 billion of IPv4, currently almost exhausted due to the exponential multiplication of devices connected thanks to the Internet of Things (IoT).Īn IPv6 network is identified through a hexadecimal combination of 8 groups of 16 bits each. IPv6 is the newest protocol and responds to the needs of an increasingly connected society with billions of devices requesting access to the Internet. The two current versions of IP protocols are IPv4 and IPv6, which diverge from each other in the number of IP addresses they support and their identification format. What is the difference between an IPv4 and an IPv6 protocol?
