1.2. IPv4 vs. IPv6: Key Differences
IPv4 (Internet Protocol version 4) and IPv6 (Internet Protocol version 6) are two versions of the Internet Protocol. IPv4 uses 32-bit addresses, allowing for approximately 4.3 billion unique addresses. IPv6, on the other hand, uses 128-bit addresses, providing a vastly larger address space of about 340 undecillion addresses. This expansion was necessary to accommodate the growing number of internet-connected devices.
| Feature | IPv4 | IPv6 |
|---|---|---|
| Address Length | 32-bit | 128-bit |
| Address Space | Approximately 4.3 billion addresses | Approximately 340 undecillion addresses |
| Notation | Dotted decimal (e.g., 192.168.1.1) | Hexadecimal, colon-separated (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334) |
| Checksum | Includes a checksum field | No checksum field; relies on link layer for error detection |
| Security | Security not built-in; relies on IPSec | Built-in security features such as IPSec |
1.3. Static vs. Dynamic IP Addresses
IP addresses can be either static or dynamic. A static IP address remains constant, while a dynamic IP address changes periodically. Static IP addresses are typically used for servers or devices that require consistent accessibility. Dynamic IP addresses are commonly assigned by ISPs to residential customers, offering flexibility and efficient use of IP address space.
1.4. Public vs. Private IP Addresses
Public IP addresses are used for communication over the internet and are unique globally. Private IP addresses are used within a private network, such as a home or office network, and are not routable on the internet. Network Address Translation (NAT) is used to translate private IP addresses to a single public IP address, allowing multiple devices on a private network to share a single internet connection.
