What is the difference between a public IP address and a local IP address? ?
A local IP address is used to identify a device within a private network, such as a home or business, and is not accessible from the Internet. In contrast, a public IP address is assigned to a device so it can communicate on the Internet, serving as a globally unique identifier to access online services and resources. Routers and firewalls play a crucial role by allowing local devices to access the Internet using a single public IP address for the entire local network. This public IP address is the one our technical support needs.
What is an IP address? ?
An IP address, or Internet Protocol address, is a numerical identifier assigned to every device connected to a computer network, whether it is a computer, smartphone, server, or any other device. This address allows each element within the network to be located and uniquely identified, by assigning it a series of numbers separated by dots (IPv4) or groups of alphanumeric characters (IPv6). IP addresses are essential for routing data on the Internet, allowing information to travel from one point to another in the digital world.
What is the difference between IPv4 and IPv6? ?
The main difference between IPv4 (Internet Protocol version 4) and IPv6 (Internet Protocol version 6) lies in how they represent IP addresses and their capacity to provide unique addresses. IPv4 uses dotted decimal notation, such as "203.0.113.25", with 32 bits, limiting the number of available addresses to approximately 4.3 billion. This limitation poses a major challenge with the growth of the Internet. In comparison, IPv6 uses hexadecimal notation separated by colons, such as "2001:0db8:85a3:0000:0000:8a2e:0370:7334", with 128 bits, offering an astronomical number of IP addresses, estimated at around 340 undecillion (a 3 followed by 38 zeros), which more than meets the needs of Internet expansion. In summary, IPv6 was designed to address the IPv4 address shortage by providing a virtually inexhaustible supply, in addition to introducing other improvements in security and efficiency.
