What are IPv4 and IPv6?
IPv4 and IPv6 are two versions of the Internet Protocol used to assign unique addresses to devices on the internet. IPv4 uses a 32-bit format (e.g., 192.168.1.1), while IPv6 uses a 128-bit format (e.g., 2001:0db8::1).
IPv4 has been the standard for years, but IPv6 was introduced to address the shortage of available IP addresses.

Here are the main differences between IPv4 and IPv6:
- Address Space: IPv4 supports about 4.3 billion addresses, while IPv6 supports 340 trillion trillion addresses.
- Format: IPv4 uses a dotted-decimal format (e.g., 192.168.1.1), while IPv6 uses a colon-separated hexadecimal format (e.g., 2001:0db8::1).
- Configuration: IPv6 supports automatic configuration, simplifying network setup compared to IPv4.
Why Transition to IPv6?
IPv6 offers enhanced security, better performance, and support for the growing number of connected devices. Transitioning to IPv6 ensures your network is future-ready.
