IPv6 gives us a much bigger address space using 128 bits, which means no more running out of IP addresses. We need it because the number of connected devices keeps growing, and IPv4 simply can’t keep up

IPv4 has lasted this long because of smart workarounds like NAT, CIDR, and private addressing, which helped stretch its limited 32-bit space and allowed networks to keep functioning efficiently. However, it’s not sustainable as its address pool is exhausted, NAT breaks end-to-end connectivity and scaling it further adds complexity. IPv6 solves… Read more
