    IPv4 has lasted this long due to <strong data-start=”1909″ data-end=”1969″>innovations like NAT, CIDR, VLSM, and private addressing, which stretched its limited capacity.

    However, it is <strong data-start=”2027″ data-end=”2046″>not sustainable because the <strong data-start=”2059″ data-end=”2089″>address space is exhausted, the number of connected devices keeps growing, and the workarounds introduce complexity and limitations.
