200-301 · Question #799

Which RFC was created to alleviate the depletion of IPv4 public addresses?

The correct answer is D. RFC 1918. RFC 1918 defines the private IPv4 address ranges, which are non-routable on the public internet and allow organizations to reuse address space internally, thus conserving public IPv4 addresses.

Why each option

RFC 1918 defines the private IPv4 address ranges, which are non-routable on the public internet and allow organizations to reuse address space internally, thus conserving public IPv4 addresses.

ARFC 4193

RFC 4193 defines Unique Local IPv6 Unicast Addresses (ULA), which are private IPv6 addresses and not related to IPv4 depletion.

BRFC 1519

RFC 1519 defines Classless Inter-Domain Routing (CIDR) architecture, which helps with efficient allocation of IP addresses but does not define private address ranges.

CRFC 1518

RFC 1518 discusses an architecture for IP address allocation, but not specifically private address ranges for alleviation of depletion like RFC 1918.

DRFC 1918Correct

RFC 1918 defines the private address spaces (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) that can be used within private networks, significantly reducing the demand for public IPv4 addresses by enabling Network Address Translation (NAT).
